(11/05/2014) In 1904, Carl Anton Larsen, a Norwegian Antarctic explorer, arrived at Grytviken on the British island of South Georgia with three ships and 60 men, to establish its first commercial whaling station. The number of whaling stations soon increased, and by 1965 these had caught and processed an estimated 175,250 whales.
Russia and China blamed for blocking Antarctic marine reserve
(11/03/2014) Another year, another failed attempt to protect a significant chunk of the Ross Sea, which sits off the coast of Antarctica. According to observers, efforts to create the world's biggest marine protected area to date were shot down by Russia and China during a meeting in Hobart, Tasmania of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR).
Saving the survivor: China scrambles to keep the finless porpoise from extinction
(10/22/2014) On the morning of July 14, 2002 Qi Qi ate breakfast as he always did. As the world’s only captive baiji – or Yangtze river dolphin – Qi Qi was something of a celebrity in China and his caretakers kept a close eye on his health. That care may explain why, after being injured by fishermen, he lived an impressive 22 years in the Freshwater Dolphin Research Center in Wuhan, China.
Saving Peru's sea turtles and marine birds: conservationists and fishermen partner to tackle bycatch
(10/07/2014) Marine conservationists often view fisheries as an enemy of sorts, vacuuming up fish with little thought to the long-term consequences and using equipment that also ends up killing other species, i.e. bycatch like sea turtles and marine birds. However, Joanna Alfaro Shigueto, the President of the Peruvian NGOProDelphinus and winner of a 2012 Whitley Award, has chosen a different tact.
Norway slaughters over 700 whales this season
(09/08/2014) As of late August, Norway has killed 729 northern minke whales (Balaenoptera acutorostrata) during its annual whaling season, the highest number taken since 1993.
California blue whales recover to historical levels
(09/05/2014) The population of blue whales in the Eastern Pacific has recovered to 97 percent of historic levels decades after Earth's largest animal was nearly driven to extinction in some places due to the whaling industry, reports a new study published in the journal, Marine Mammal Science.
Coastal wildlife paradise declared biosphere reserve in Argentina (PHOTOS)
(07/15/2014) Conservationists are celebrating the announcement that UNESCO has dubbed Argentina's Península Valdés a biosphere reserve under the Man and Biosphere Program (MBA). A hatchet-shaped peninsula that juts out into the Southern Atlantic Ocean, the world's newest biosphere reserve is home to a hugely-diverse collection of both terrestrial and marine wildlife.
Scientists uncover new marine mammal genus, represented by single endangered species
(05/14/2014) This is the story of three seals: the Caribbean, the Hawaiian, and the Mediterranean monk seals. Once numbering in the hundreds of thousands, the Caribbean monk seal was a hugely abundant marine mammal found across the Caribbean, and even recorded by Christopher Columbus during his second voyage, whose men killed several for food.
Collateral damage: new findings shed light on the full impact of commercial fishing
(04/09/2014) Aside from reducing the populations of the species sought for capture, commercial fisheries are also killing thousands of nontarget creatures such as sharks, albatross, and sea turtles, collectively referred to as “bycatch.” However, the full extent of the problem is only beginning to be grasped.
Scientists spy on whales from space
(03/11/2014) Although whales are the biggest animals on the planet, scientists have found in difficult to count them. But a new study in PLOS ONE may change this: researchers tested the idea of counting whales using high resolution satellite imagery. Employing a single image from the WorldView2 satellite, scientists went about counting a pod of southern right whales in the Golfo Nuevo off the coast of Argentina.
Scientists discover new whale species
(02/14/2014) Beaked whales are incredibly elusive and rare, little-known to scientists and the public alike—although some species are three times the size of an elephant. Extreme divers, beaked whales have been recorded plunging as deep as 1,800 meters (5,900 feet) for over an hour. Few of the over 20 species are well-known by researchers, but now scientists have discovered a new beaked whale to add to the already large, and cryptic, group: the pointed beaked whale (Mesoplodon hotaula).
Incredible encounter: whales devour European eels in the darkness of the ocean depths
(02/11/2014) The Critically Endangered European eel makes one of the most astounding migrations in the wild kingdom. After spending most of its life in Europe's freshwater rivers, the eel embarks on an undersea odyssey, traveling 6,000 kilometers (3,720 miles) to the Sargasso Sea where it will spawn and die. The long-journeying eels larva than make their way back to Europe over nearly a year. Yet by tracking adult European eels (Anguilla anguilla) with electronic data loggers, scientists have discovered that some eels never make it to their spawning ground, but instead are swallowed-up in the depths by leviathans.
Photos: Japanese fishermen slaughter 41 dolphins, capture 52 in 'The Cove'
(01/21/2014) The annual dolphin hunt in Taiji, Japan ended on Monday with dozens being slaughtered for meat and captured for sale to amusement parks, reports Sea Shepherd, an ocean activist group that campaigns against the practice and just released photos documenting the weekend's harvest.
Over 75 percent of large predators declining
(01/09/2014) The world's top carnivores are in big trouble: this is the take-away message from a new review paper published today in Science. Looking at 31 large-bodied carnivore species (i.e those over 15 kilograms or 33 pounds), the researchers found that 77 percent are in decline and more than half have seen their historical ranges decline by over 50 percent. In fact, the major study comes just days after new research found that the genetically-unique West African lion is down to just 250 breeding adults.
Japanese whale hunt stopped, for now
(01/06/2014) Anti-whaling group Sea Shepherd said its fleet of ships has successfully disrupted the annual Japanese whale hunt in the waters off Antarctica.
Activists urge Southwest to drop SeaWorld over whale concerns
(01/06/2014) More than 27,000 people have signed a petition calling on Southwest Airlines Co. (LUV) to drop its partnership with SeaWorld Entertainment, Inc. (NYSE:SEAS), over the theme park's treatment of its marine mammals, reports Change.org, the site that is hosting the petition.
Global warming could upset Antarctic food chain
(01/02/2014) Resting near the bottom of the foodchain, Antarctic krill (Euphausia superba) underpin much of the Southern Ocean's ecosystem. But in a rapidly warming world, these hugely-abundant crustaceans could see their habitat shrink considerably. In a recent paper in PLOS ONE, scientists predict that Antarctic krill could lose 20 percent of their growth habitat, or 1.2 million square kilometers.
Sonar directly impacts whale behavior, according to military study
(12/13/2013) Noises from pile-driving, explosives, ship motors and other industrial activities have all been linked to adverse effects on marine wildlife. A new study, funded by the US Navy and published in Proceedings of the Royal Society B, suggests that military sonar may be directly impacting whale behavior. The idea that sonar might affect the behavior of whales is not new. A number of reports in the past have linked the use of military sonar to mass stranding events of beaked whales and baleen whale species.
Where have all the dugongs gone?
(12/03/2013) Legend has it that lonely sailors mistook them for beautiful, mythical mermaids. But as it turns out, the muse behind these beguiling sea nymphs was instead the dugong – a rather ungainly, gentle and mini-bus sized marine mammal, cousin to the manatees and part of the sea cow family. However, while they may have once fuelled stories for fairytales and Disney movies, their far-from-glamorous life is currently under serious threat in many parts of the world.
DNA tests reveal new dolphin species (photos)
(10/30/2013) With the help of DNA tests, scientists have declared a new dolphin species that dwells off the coast of northern Australia. The discovery was made after a team of researchers looked at the world's humpback dolphins (in the genus Sousa), which sport telltale humps just behind their dorsal fins. While long-known to science, the new, as-yet-unnamed species was previously lumped with other humpback dolphins in the Indo-Pacific region.
Fishermen illegally killing dolphins for shark-bait in Peru (video)
(10/23/2013) Peruvian fishermen slaughtered dolphins to use as bait for shark fishing, an undercover investigation has revealed. Footage showed infant and adult dolphins being harpooned then stabbed and clubbed before, in some cases, being cut open and butchered while still alive. The slaughtered dolphins were cut up and used as bait. Dolphins are also killed for human consumption in Peru even though it is illegal.
African manatee hanging on in Cameroon
(09/30/2013) In the Lower Basin of the Sanaga River in Cameroon, near Lake Ossa and the Douala-Edea National Parks, manatees swim and float about like round, potato-shaped mermaids. This region is home to the West African manatee (Trichechus senegalensis), an aquatic mammal facing a decline in population. Classed as Vulnerable by the IUCN Red List, the West African manatee is threatened by excessive kills, habitat loss, and habitat degradation. Given this, and the dearth of information about manatees, a group of Cameroon scientists have taken an ethnobiological approach (i.e. the interaction between people and wildlife) by employing skilled, knowledgable locals to collect data on the manatees.
Sonar used by oil company caused mass whale stranding in Madagascar
(09/25/2013) An oil company's use of a high-frequency mapping sonar system was responsible for a mass whale stranding in northwest Madagascar in 2008, finds a new report.
Climate change killing harp seal pups
(08/20/2013) As sea ice levels continue to decline in the northern hemisphere, scientists are observing an unsettling trend in harp seal young mortalities regardless of juvenile fitness. While a recent study found that in harp seal breeding regions ice cover decreased by up to 6% a decade from 1979 on, a follow-up study in PLoS ONE compared the rate of harp seal strandings to total ice cover from 1992 to 2010.
Climate change scattering marine species
(08/08/2013) Rising ocean temperatures are rearranging the biological make-up of our oceans, pushing species towards the poles by 7kms every year, as they chase the climates they can survive in, according to new research. The study, conducted by a working group of scientists from 17 different institutions, gathered data from seven different countries and found the warming oceans are causing marine species to alter their breeding, feeding and migration patterns.
Galapagos sea lions threatened by human exposure
(07/19/2013) A recent study conducted by the Zoological Society of London (ZSL) on endangered Galapagos sea lions (Zalophus wollebaeki) has revealed that the animals are more susceptible to starvation as a result of their exposure to humans. Over a span of more than 18 months, conservationists tagged and monitored the behavior and physiology of two groups of 60 Galapagos sea lions, one in San Cristobal, which is inhabited by humans, and one in Santa Fe, where there are no humans, dogs, cats, mice, or rats.
Yangtze finless porpoise drops to Critically Endangered
(07/07/2013) The newest update to the IUCN Red List has downgraded the status of the Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) from Endangered to Critically Endangered, reflecting the deteriorating state of arguably the world's most degraded river system. The downgrade follows a survey last year that counted only 1,000 animals, a 50 percent decline from 2006.
Australia aims to end Japan's whaling
(06/27/2013) Australia is hoping to put a permanent end to Japan's annual slaughter of hundreds of whales in the Southern Ocean, in a landmark legal challenge that begins this week. Australia, a vocal opponent of Japan's annual "scientific" hunts in the Antarctic, says it is confident that the international court of justice (ICJ) in The Hague will outlaw the hunts at the end of a highly anticipated case that is due to start on Wednesday.
Whales teach each other new feeding behavior
(05/29/2013) Humpback whales (Megaptera novaeangliae), popularly known for their majestic and alluring underwater mating songs and acrobatic breaches, have shown that they can adapt to changing prey variability by passing on new hunting techniques to each other. According to new findings in the journal Science, a team of researchers have revealed the cultural spread of new hunting techniques through a population of humpback whales over the span of 27 years.
Are seagulls killing whales in Patagonia?
(05/08/2013) It sounds ludicrous, but it could just be true: scientists say seagulls may be responsible for hundreds of southern right whale moralities off the Argentine coastline. Since 2003, scientists have documented the deaths of 605 southern right whales (Eubalaena australis) near Península Valdés which the whales use as a nursery. Notably, 88 percent of these were newborn calves. The death rate is so high that researchers now fear for the whales' long-term survival.
Munching on marine plastic kills sperm whale
(05/07/2013) What do children's toys, balloons, mattresses and plastic bags have in common? They can, along with more non-biodegradable pollutants, be found in the belly of a sperm whale, the topic of a new study in the Marine Pollution Bulletin. The same whale that swallowed Jonah from the Bible, Geppetto from Collodi's Pinocchio, and the crew of the Pequod from Melville's Moby-Dick is now swallowing trash from the Spanish-Mediterranean coast, and in the Strait of Gibraltar.
Japan killed record low number of whales
(04/05/2013) Japan blamed environmental activists for a "record low" take during this year's whaling season in the Southern Ocean, reports Kyodo News.
Photo: Pod of 100,000 dolphins spotted off California coast
(02/21/2013) A 'super mega-pod' of some 100,000 dolphins was spotted off the coast of San Diego last week, according to a report from NBC San Diego.
From the brink of extinction: elephant seals stage remarkable comeback
(01/23/2013) In the 19th century the Northern Pacific Elephant was thought to be extinct until a small population was discovered on an island of Baja California in 1892. Since then, the species has staged a remarkable comeback which was greatly accelerated by protective measures adopted by the U.S. and Mexican governments. The recovery is especially evident on the beaches of California's Año Nuevo State Park. Until the 1950s so individuals were observed in the park. In the 1960s pups started to be born on Año Nuevo's sandy shores. By the 1990s thousands of pups where born each year, capping the elephant seal's turnaround. 'Beachmaster', a new film by Christopher Gervais and Stan Minasian, tells the conservation success story of their recovery.
Save Lolita: new film urges release of captive killer whale
(01/22/2013) Through his new 90-second PSA, Save Lolita, filmmaker Daniel Azarian wanted to connect people to the plight of Lolita on a deeply human level; the only problem: Lolita is an orca, also known as a killer whale. But the stark, moving PSA succeeds, given the sociability of an individual—human or orca—who was stolen from her family and held in captivity for the past 42 years at Miami's Seaquarium.
Reduction in snow threatens Arctic seals
(11/28/2012) Arctic snowfall accumulation plays a critical role in ringed seal breeding, but may be at risk due to climate change, according to a new study in Geophysical Research Letters. Sea ice, which is disappearing at an alarming rate, provides a crucial platform for the deep snow seals need to reproduce. Ringed seals (Phoca hispida) require snow depths of at least 20 centimeters (8 inches): deep enough to form drifts that seals use as birth chambers.
Photos: Mozambique creates Africa's biggest marine protected area
(11/13/2012) Last week, the East African nation of Mozambique announced it was protecting 10,411 square kilometers (4,020 square miles) of coastal marine waters, making the new Marine Protected Area (MPA) the biggest on the continent. The protected area, dubbed the Primeiras and Segundas Archipelago ("First" and "Second" islands), includes ten islands as well as mangrove forests, rich coral reefs, and seagrass ecosystems.
Whale only known from bones washes up on beach in New Zealand
(11/05/2012) In 2010, a whale mother and male calf were found dead on Opape Beach in New Zealand. Although clearly in the beaked whale family—the most mysterious marine mammal family—scientists thought the pair were relatively well-known Gray's beaked whales (Mesoplodon grayi). That is until DNA findings told a shocking story: the mother and calf were actually spade-toothed beaked whales (Mesoplodon traversii), a species no one had ever seen before as anything more than a pile of bones.
By imitating human voices, beluga whale may have been attempting to communicate
(10/23/2012) Five years after the death of a captive beluga whale named NOC, researchers have discovered that the marine mammal may have been trying to communicate with people by mimicking humans voices at the National Marine Mammal Foundation in San Diego. Analyzing tapes of human-like speech from the young male beluga whale, scientists writing in Current Biology note that while there have been reports of beluga whales making human like sounds before, this is the first time evidence has been captured on tape and analyzed.
Photos: emperor penguins take first place in renowned wildlife photo contest
(10/18/2012) Photographer, Paul Nicklen, says he'll never forget the moment when a slew of emperor penguins burst by him in the frigid Ross Sea; he'd waited in the cold water, using a snorkel, to capture this image. Now, Nicklen has won the much-coveted Veolia Environnement Wildlife Photographer of the Year Competition for the antic, bubbling photograph. Owned by the Natural History Museum and BBC Worldwide, this is the 48th year of the Veolia Environnement Wildlife Photographer of the Year, which hands out awards to 100 notable wildlife and environment photos.
Cute animal picture of the day: baby walruses on the mend
(10/11/2012) Two walrus male calves were discovered over the summer near Barrow, Alaska, dehydrated and ill, after their separate mothers perished. The calves have been receiving care at the Alaska SeaLife Center, but one will soon be moved to the Wildlife Conservation Society's (WCS) New York Aquarium and the other to the Indianapolis Zoo.
Maui's dolphins still in danger of extinction despite New Zealand's protective measures
(08/07/2012) The New Zealand government's recent efforts to protect the world’s smallest dolphin have come under scrutiny from various conservation organizations at the 64th meeting of the International Whaling Commission (IWC). There are only 55 Maui dolphins (Cephalorhynchus hectori maui) now found on the west coast of New Zealand’s North Island, less than half the 2005 population with numbers continuing to decline. Less than 20 of the remaining Maui’s are breeding females and their slow reproductive rates make it difficult to increase their numbers when faced with an even bigger danger: fishing nets.
Humpback whales delaying migration due to Antarctic changes
(07/30/2012) Humpback whales in the Antarctic are delaying their migration to feed on krill that are staying later due to reduced extent of sea ice, a possible consequence of climate change, reports a study published in the journal Endangered Species Research.
Deepwater Horizon oil spill may have played role in dolphin deaths
(07/22/2012) In the first four months of 2011, 186 bottlenose dolphins (Tursiops truncatus) were found dead in the Gulf of Mexico, nearly half of them dolphin calves many of whom were perinatal, or near birth. Researchers now believe a number of factors may have killed the animals. Writing in the open-access journal PLoS ONE, scientists theorize that the dolphins died a sudden influx of freshwater from snowmelt after being stressed and weakened by an abnormally cold winter and the impacts of the BP oil spill.
Cute animal picture of the day: stranded sea lion finds new home
(07/11/2012) A young female California sea lion (Zalophus californianus) , who had stranded herself three times, has found a new home at the Bronx Zoo. After her most recent escapade of showing up at a beachside bar in California, experts decided she was too habituated to humans to re-release back into the ocean for a third time. She was transferred to the Wildlife Conservation Society's Bronx Zoo.
Just how far can a polar bear swim?
(05/03/2012) Polar bears (Ursus maritimus) are capable of swimming incredible distances, according to a new study published in Zoology, which recorded polar bears regularly swimming over 30 miles (48 kilometers) and, in one case, as far as 220 miles (354 kilometers). The researchers believe the ability of polar bears to tackle such long-distance swims may help them survive as seasonal sea ice vanishes due to climate change.
Over 30 Yangtze porpoises found dead in China as population nears extinction
(05/01/2012) Six years after the Yangtze river dolphin (Lipotes vexillifer), or baiji, was declared "functionally extinct" by scientists, another marine mammal appears on the edge of extinction in China's hugely degraded Yangtze River. In less than two months, 32 Yangtze finless porpoises (Neophocaena asiaeorientalis asiaeorientalis), a subspecies of the finless porpoise, have been dead found in Dongting and Poyang Lakes in the Yangtze, reports the World Wide Fund for Nature (WWF).
Video: All white killer whale spotted in Russia
(04/27/2012) Scientists in Russia have captured the first-known video footage of an all-white killer whale.
BP Deepwater Horizon deformities: eyeless shrimp, clawless crabs
(04/24/2012) Two years after the BP-leased Deepwater Horizon drilling rig exploded in the Gulf of Mexico, killing eleven and causing an oil spill that lasted three months, scientists say the impacts on the Gulf ecosystem are only beginning to come to light and the discoveries aren't pretty.
World's smallest dolphin: only 55 left, but continue to drown in nets
(03/22/2012) The world's smallest dolphin is also the closest to extinction. New Zealand government figures show that Maui's dolphin (Cephalorhynchus hectori maui) are down to just 55 mature individuals, falling from 111 in 2005. The small cetaceans, measuring up to 1.7 meters (5.5 feet), are imperiled due to drowning in gillnets with the most recent death by a fisherman's net occurring in January.
Featured video: scientists capture first footage of Shepherd's beaked whale
(02/27/2012) Scientists have captured what is believed to be the world's first footage of the cryptic Shepherd's beaked whale (Tasmacetus shepherdi), one of a number of beaked whale species about which scientists know almost nothing.
Amazon.com stops selling whale meat
(02/22/2012) Amazon Japan, a subsidiary of Amazon.com, pulled all whale meat products (and possibly dolphin meat) from its site after a new report by the Environmental Investigation Agency (EIA) and the Humane Society International highlighted the issue. Last December the organizations recorded 147 whale products on sale at Amazon Japan despite an international whaling moratorium since 1986. Japan, along with Iceland and Norway, continues to industrially hunt whales. Japan says their whale hunt is for scientific purposes only, but environmentalists dispute this.
New sanctuaries declared for Asia's freshwater dolphins
(02/15/2012) Bangladesh has declared three new sanctuaries to help protect the south Asian river dolphin (Platanista gangetica) in the Sundarbans, the world's largest mangrove forest. Split into two subspecies, the Ganges River dolphin (Platanista gangetica gangetica) and the Irrawaddy River dolphin (Platanista gangetica minor), the new sanctuaries will benefit both. Listed as Endangered by the IUCN Red List, the south Asian freshwater dolphin has disappeared from much of its habitat. Already Asia has its other freshwater dolphin species: the baiji (Lipotes vexillifer) was declared functionally extinct into 2006 after a survey of the Yangtze River failed to find a single individual.
87 marine mammals still eaten by people
(01/24/2012) Threats to marine mammals usually include climate change, drowning as by-catch, pollution, depletion of prey, but what about eating marine mammals? A new study in Biological Conservation finds that a surprising 87 marine mammals—including polar bears, small whales, and dolphins—have been eaten as food since 1990 in at least 114 countries.
Photos: program devoted to world's strangest, most neglected animals celebrates five years
(01/16/2012) What do Attenborough's echidna, the bumblebee bat, and the purple frog have in common? They have all received conservation attention from a unique program by the Zoological Society of London (ZSL) called EDGE. Five years old this week, the program focuses on the world's most unique and imperiled animal species or, as they put it, the most Evolutionarily Distinct and Globally Endangered (EDGE) species. In the past five years the program has achieved notable successes from confirming the existence of long unseen species (Attenborough's echidna) to taking the first photos and video of a number of targeted animals (the purple frog).
Featured video: tuna industry bycatch includes sea turtles, dolphins, whales
(01/16/2012) A Greenpeace video, using footage from a whistleblower, shows disturbing images of the tuna industry operating in the unregulated waters of the Pacific Ocean. Using fish aggregation devices (FADs) and purse seine nets, the industry is not only able to catch entire schools of tuna, including juvenile, but also whatever else is in the area of the net.
How much is the life of a whale worth?
(01/16/2012) How do you end a decades-long conflict between culture and conservation? How do you stop a conflict where both sides are dug in? A new paper in Nature proposes a way to end the long and bitter battle over whaling: environmentalists could pay whalers not to whale.
Cute animal picture of the day: pygmy killer whale saved after stranding
(01/12/2012) On Tuesday a female pygmy killer whale (Feresa attenuata) was found stranded on Tanjung Aru beach, in the Malaysian state of Sabah on the island of Borneo. After being moved to a swimming enclosure at a local resort for recuperation, the whale was released back into the wild with aid from the Sabah Wildlife Department, marine biologist Lindsay Porter, the local NGO LEAP, and WWF Malaysia.
Seals, birds, and alpine plants suffer under climate change
(01/11/2012) The number of species identified by scientists as vulnerable to climate change continues to rise along with the Earth's temperature. Recent studies have found that a warmer world is leading to premature deaths of harp seal pups (Pagophilus groenlandicus) in the Arctic, a decline of some duck species in Canada, shrinking alpine meadows in Europe, and indirect pressure on mountain songbirds and plants in the U.S. Scientists have long known that climate change will upend ecosystems worldwide, creating climate winners and losers, and likely leading to waves of extinction. While the impacts of climate change on polar bears and coral reefs have been well-documented, every year scientists add new species to the list of those already threatened by anthropogenic climate change.
Critically Endangered Hawaiian monk seals bludgeoned to death
(01/08/2012) To date three Hawaiian monk seals (Monachus schauinslandi), and possibly a fourth mortality under investigation, have been found bludgeoned to death by an as yet undiscovered assailant, reports the Associated Press. Authorities believe the seals may have been killed by local fishermen who fear new regulations meant to save the species from extinction. The seal is currently down to 1,100 individuals.
Small marine fish need protection too
(10/25/2011) It has long been known that overfishing has decimated some populations of tuna, shark, cod, as well as other big predatory fish; however two recent studies have pointed out that overfishing is also threatening small fish such as anchovies, sardines, mackerel, herring, menhaden, and krill. Although tiny, these species are vital to marine ecosystems since many species higher up on the food chain—from seabirds to marine mammals to big fish—wholly depend on them for survival.

Photos: satellite tracking of the unicorn of the sea
(10/19/2011) A new program aims to track one of the ocean's most enigmatic creatures: the narwhal (Monodon monoceros). Tagging nine narwhales in August, researchers plan to track the species in order to gain new insights about how the little-known toothed whale will withstand a rapidly melting Arctic due to climate change. "[This] is a chance to better understand these animals while their world changes around them. We know narwhals are often associated with sea ice, and we know the sea ice is shrinking. WWF is trying to understand how narwhals, as well as all other ice associated animals in the arctic can adapt to a changing environment," says Peter Ewins with WWF-Canada.
Photos: New Zealand oil disaster kills over 1200 birds to date
(10/16/2011) According to the New Zealand government an oil spill from a grounded container ship in the Bay of Plenty has killed 1,250 seabirds with hundreds of others in rescue centers. However, conservationists say the avian death-toll is far higher with most contaminated birds simply vanishing in the sea. "The number of birds being found washed up on the beaches will be a very small proportion of the birds being affected," explained Karen Baird, Seabird Conservation Advocate with NGO Forest & Bird.
Deepwater spill 'meets the Titanic': groups sue to stop Arctic drilling
(09/29/2011) Following the Obama administration's approval of Royal Dutch Shell to drill in the Arctic's Beaufort Sea, a wide-swathe of environmental have filed a lawsuit to stop the drilling, which could begin as early as next summer. Those filing the lawsuit today blasted Shell for what they perceived as a pathetic oil spill response plan, and the Obama administration for acquiescing to the big oil company.

Sowing the seeds to save the Patagonian Sea
(09/07/2011) With wild waters and shores, the Patagonia Sea is home to a great menagerie of marine animals: from penguins to elephants seals, albatrosses to squid, and sea lions to southern right whales. The sea lies at crossroads between more northern latitudes and the cold bitter water of the Southern Ocean, which surround Antarctica. However the region is also a heavy fishing ground, putting pressure on a number of species and imperiling the very ecosystem that supplies the industry. Conservation efforts, spearheaded by marine conservationist Claudio Campagna and colleagues with the Wildlife Conservation Society (WCS), are in the early stages. Campagna, who often writes about the importance of language in the fight for preservation, has pushed to rename the area to focus on its stunning wildlife.
Mass walrus haul-outs, polar bear cub mortality linked to climate change
(09/01/2011) Recent, unprecedented walrus haul-outs and increased instances of long-distance swims by polar bears show the direct impacts on wildlife of dwindling Arctic sea ice from climate change. These threatened species also face the prospect of offshore drilling in the Arctic after the Obama Administration recently approved a number of plans to move forward on oil exploration. At least 8,000 walruses hauled out on an Alaskan beach along the Chukchi Sea on August 17. Only a day before, the U.S. Geological Survey announced it would begin tagging walruses near Point Lay, Alaska to study how a lack of sea ice is affecting the species.
Decline in top predators and megafauna 'humankind’s most pervasive influence on nature'
(07/14/2011) Worldwide wolf populations have dropped around 99 percent from historic populations. Lion populations have fallen from 450,000 to 20,000 in 50 years. Three subspecies of tiger went extinct in the 20th Century. Overfishing and finning has cut some shark populations down by 90 percent in just a few decades. Though humpback whales have rebounded since whaling was banned, they are still far from historic numbers. While some humans have mourned such statistics as an aesthetic loss, scientists now say these declines have a far greater impact on humans than just the vanishing of iconic animals. The almost wholesale destruction of top predators—such as sharks, wolves, and big cats—has drastically altered the world's ecosystems, according to a new review study in Science. Although researchers have long known that the decline of animals at the top of food chain, including big herbivores and omnivores, affects ecosystems through what is known as 'trophic cascade', studies over the past few decades are only beginning to reveal the extent to which these animals maintain healthy environments, preserve biodiversity, and improve nature's productivity.
Animal picture of the day: humpback whale breaching
(07/12/2011) The humpback whale (Megaptera novaeangliae) is a conservation success story. Decimated by centuries of whaling, most populations have risen since a moratorium was placed on commercial whaling in the 1966. Today, over 60,000 humpback whales migrate through the world's oceans, though this is still considerably less than the historic population.
The truth about polar bears and climate change
(06/21/2011) Although scientists say innumerable species are threatened by climate change, polar bears have been the global symbol of the movement to rein-in greenhouse gas emissions. This is perhaps not surprising, since polar bears are well known to the public—even though they inhabit a region largely absent of humans—and they make a big impression. Their glaringly white coat contrasts with their deadly skills: as the world's biggest terrestrial predators, they are capable of killing a seal with single blow. When young they are ridiculously adorable, but when adults they are stunning behemoths. But that's not all. Unlike many other species, the perils of climate change are also easy to visualize in connection with polar bears: their habitat is literally melting away.
Russia and Norway carve up wildlife-rich Arctic sea for fossil fuels
(06/09/2011) As climate change melts the Arctic sea ice, nations are rushing to carve up once-inaccessible areas for oil and gas exploitation, industrial fishing, and shipping routes. Now, BBC reports that Russia and Norway have essentially agreed to split the Arctic's Barents Sea in half —one of the region's richest in biodiversity and ecological productivity—for industrial exploitation.
Expedition granted?: hoping to save nearly-extinct seals through National Geographic contest
(03/24/2011) Dashiell Masland, known as 'Dash', has always been in love with the sea and its inhabitants. Now, she is hoping to take that passion to the Hawaiian Islands to save one of the world's most threatened marine mammals: the Hawaiian monk seals (Monachus schauinslandi). Extinction is a real possibility: already, the related Carribbean monk seal vanished forever around 1950. Decimated by sealers, whalers, and even soldiers in World War II, the Hawaiian monk seals are struggling to make a come back with only 1,100 individuals surviving and the population decreasing by 4% a year. Today many face starvation due to a lack of prey. This is where Masland, who is currently competing in National Geographic's Expedition Granted, hopes to help.
India plans to aid dwindling Ganges River dolphin
(03/08/2011) The Indian government has announced that it plans to develop a program to raise the population of its native Ganges river dolphin (Platanista gangetica gagnetica), a subspecies of the South Asian river dolphin. During a question and answer session Jairam Ramesh, India's Environment and Forests Minister, said that the dolphin's current population was estimated at 2,000 to 3,000 individuals in the Ganges. However, other estimates have placed it lower.
Dead baby dolphins washing ashore in Gulf of Mexico
(02/28/2011) Every year a few baby dolphins in the Gulf don't make it and are found on the shores of the Gulf, but this year something is different. To date, 24 baby dolphins have been found dead in Alabama and Georgia, some are stillborn, others aborted fetuses. Researchers, who say death-toll is ten times the average, are currently studying the dead porpoises for clues to cause. These could include colder-than-average waters, algal blooms, disease, or the incident in the back of everyone's mind: the BP oil spill last year.
India pledges to protect cat-crazy rainforest
(02/14/2011) The Jeypore-Dehing lowland rainforest in Assam, India is home to a record seven wild cat species, more than any other ecosystem on Earth. While it took wildlife biologist Kashmira Kakati two years of camera-trapping to document the seven felines, the announcement put this forest on the map—and may very well save it. A year after the record was announced, officials are promising to pursue permanent preservation status for the forest, which is threatened by logging, poaching, oil and coal industries, and big hydroelectric projects.
Kite-photography gives new perspective to whale migration
(12/22/2010) A new project sponsored by Nokia uses KAPing - kite aerial photography - to get an innovative look at whale behavior. The project will be taking place in Hawaii and will document the area's annual humpback whale migration.
Photos: wild, weird, and rare mammals storm the conservation world
(11/21/2010) What do the New Zealand greater short-tailed bat, the black-and-white ruffed lemur, and the numbat have in common? They are all new members of the Zoological Society of London's EDGE top 100 most endangered and unique mammals list. Arguably the most innovative conservation program in the world, EDGE decides which species to focus conservation efforts on not based on popularity or fund-raising potential, but on hard data, only working with species that are considered the most endangered and evolutionarily distinct.
Massive shark sanctuary declared in the Coral Triangle
(11/17/2010) A shark sanctuary has been declared around the Raja Ampat islands in Indonesia. Larger than Denmark, the new sanctuary covers 17,760 square miles (46,000 square kilometers) of one of the world's richest marine biodiverse region, the Coral Triangle. Protections not only cover sharks, but dugongs, marine turtles, mobulas, and manta rays as well. In addition, reef bombing and fishing for the aquarium trade are banned.
What do wolves and sharks have in common?
(11/15/2010) Sharks dwell in the ocean, wolves on land; sharks are a type of fish, wolves are a mammal; sharks go back some 400 million years, wolves only some 2 million years. So, these animals should have little in common, right? However, a new study in Frontiers in Ecology and the Environment points to surprising similarities among these disparate animals. As top predators, both wolves and sharks impact their prey and other species in similar ways.
Sustainably certified fishery kills over 250 fur seals in one season
(11/10/2010) The New Zealand Ministry of Fisheries estimates that from 2007-2008, 273 New Zealand fur seals (Arctocephalus forsteri) were killed by offshore trawling hoki fisheries, an increase of over 75 seals since the previous year. New Zealand's hoki fishery has been certified as sustainable by the Marine Stewardship Council since 2001 and re-certified in 2007. Hoki is commonly used for ubiquitous fried fish sandwiches, such as those served at McDonald's.
Japanese making themselves sick with dolphin hunt
(11/01/2010) Japan's dolphin hunt of Dall's porpoise (Phocoenoides dalli) could be making people sick, according to a new study by the Environmental Investigation Agency (EIA) and Campaign Whale. The controversial hunt, which kills some 15,000 dolphins annually, produces cheap meat-for-consumption that on average contains over double Japan's limit on mercury contamination. "We are very concerned that people in Japan are threatening their health and possibly that of their children by unwittingly eating Dall’s porpoise meat that is dangerously contaminated with poisons such as mercury and PCBs," Andy Ottaway, Director of Campaign Whale, said in a press release.
Island nation announces Ukraine-sized sanctuary for whales and dolphins
(10/24/2010) Dolphins, whales, and dugongs will be safe from hunting in the waters surrounding the Pacific nation of Palau. At the Convention on Biological Diversity (CBD) in Nagoya, Japan, Palau's Minister of the Environment, Natural Resources and Tourism, Harry Fritz, announced the establishment of a marine mammal sanctuary covering over 230,000 square miles (60,000 square kilometers) of the nation's waters, an area the size of Mongolia.
Cold snap may have killed millions of fish in Bolivia, poisoning rivers
(08/31/2010) Although the last few months have been some of the warmest worldwide on record, including 17 countries reaching or breaking all-time highs, temperatures have not been above average everywhere. Cold air from Antarctica has brought chilling temperatures to parts of South America, including Bolivia where millions of fish and thousands of caimans, turtles, and river dolphins have perished according to Nature Communications.
Scientists condemn current development plan in Kalimantan
(08/02/2010) Scientists with the Association for Tropical Biology and Conservation (ATBC) have released a resolution opposing the current development plan for a road and bridge crossing Balikpapan Bay in the Indonesian state of Kalimantan. The resolution states that the plan threatens not only the fragile ecosystems within the bay, but of the nearby mangroves as well as the Sungai Wain forest and its watershed, vital for local industry and people. According to ATBC, the plan could be easily remedied by officials picking an alternate route, which is also favored by locals since it would be 80 kilometers shorter.
Who's really accountable for the BP oil spill?
(07/25/2010) Reading articles in the newspapers recently and online, I find the media's focus is on scrutinizing BP's way of paying for the damage done when an estimated 76,934,000 gallons of their oil leaked out into the Gulf of Mexico after the explosion of their Deepwater Horizon rig in April. It is not that they are being criticised for not standing up and taking full responsibility for their recklessness that caused the spill, but instead they are being accused of not paying enough money for its clean-up. Taxpayers are outraged that they may pick-up the tab and are demanding to know why they should be held accountable when the disaster wasn’t their fault. Yet, do we not all have a part to play in this catastrophe?
Oil disaster threatens Gulf of Mexico's deep water titans
(07/19/2010) As I discovered in the course of researching my book, No Rain in the Amazon: How South America’s Climate Change Affects the Entire Planet (Palgrave, 2010), the oil industry has had a poor record when it comes to protecting aquatic sea life. Take for example the manatee, which has been put at risk from the Amazon to the Gulf of Mexico as a result of the oil industry. One of the most outlandish creatures on the planet, the shy and retiring manatee, which gets its name from an American Indian word meaning “Lady of the Water,” was first described as a cross between a seal and hippo. The creature has a wonderfully round body, mostly black skin the texture of vinyl, a bright pink belly, a diamond-shaped tail and a cleft lip.
Conservation photography: on shooting and saving the world's largest temperate rainforest, an interview with Amy Gulick
(07/11/2010) Most of the US's large ecosystems are but shadows of their former selves. The old-growth deciduous forests that once covered nearly all of the east and mid-west continental US are gone, reduced to a few fragmented patches that are still being lost. The tall grassy plains that once stretched further than any eye could see have been almost wholly replaced by agriculture and increasing suburbs. Habitats, from deserts to western forests, are largely carved by roads and under heavy impact from resource exploitation to invasive species. Coastal marine systems, once super abundant, have partially collapsed in many places due to overfishing, as well as pollution and development. Despite this, there are still places in the US where the 'wild' in wilderness remains largely true, and one of those is the Tongass temperate rainforest of Southeast Alaska.
In the midst of marine collapse will we save our last ocean?
(07/05/2010) Imagine an ocean untouched by oil spills: a sea free of pollution, invasive species, dead zones, and over-exploitation; waters where marine animals exist in natural abundance and play ecological roles undimmed by mankind. Such a place may sound impossible in today's largely depleted oceans, but it exists: only discovered in 1841, the Ross Sea spreads over nearly a million kilometers adjacent to the Antarctic continent. Here killer whales, penguins, sea birds, whales, and giant fish all thrive. However, even with its status as the world's 'last ocean', the Ross Sea has not escaped human impact. Over the last 15 years commercial fisheries have begun to catch one of its most important species in the ecosystem to serve them up on the dinner plates of the wealthy.
Whaling talks break down: ban stays in place, yet whaling will continue
(06/23/2010) The International Whaling Commission (IWC), which was supposed to decide a way forward for whales over the next decade has ended without an agreement. Talks broke down, according to participants, because countries opposed to whaling and those that continue hunting and killing whales despite a ban on commercial whaling—i.e. Japan, Norway, and Iceland—have been unable to find enough common ground to pound out an agreement.
To whale or not to whale?: nations, environmental groups do some soul-searching
(06/22/2010) There are two ways forward on whaling according to visions being put forward at the International Whaling Commission this week. One way is to uphold the 24-year-long ban on hunting and killing whales. While this road sends a strong pro-conservation message, it also means that Japan, Norway, and Iceland will continue whaling as they have over the past couple decades, killing an average of 2,000 whales annually. These three countries employ a variety of excuses for their whaling—Iceland and Norway simply state that they do not recognize the whaling ban while Japan claims its whaling is only done for 'scientific purposes'—but it is clear that they will not end whaling and, to date, there is no punishment for their dismissal of the international treaty.
The penguin crisis: over 60 percent of the world's penguins threatened with extinction
(06/10/2010) Everyone loves penguins. With their characteristic black-and-white 'tuxedo' markings, upright waddle, and childlike stature, penguins seem at once exotic and familiar: exotic because they live far from most human habitations, familiar because they appear in innumerable books and movies. From Mr. Popper's Penguins to Happy Feet, and from March of the Penguins to And Tango Makes Three, penguins pop-up everywhere. The flightless birds have even provided the name and symbol to one of the world's most successful publishing houses. Yet despite their popularity amid the human kingdom, few people seem aware that penguins worldwide are facing an extinction crisis.
Will we ever know the full wildlife toll of the BP oil spill?
(06/08/2010) Will we ever know the full wildlife toll of the BP oil spill? The short answer: no. The gruesome photos that are making the media rounds over the last week of oiled birds, fish, and crustaceans are according to experts only a small symbol of the ecological catastrophe that is likely occurring both in shallow and deep waters. Due to the photos, birds, especially the brown pelican, have become the symbol of the spill to date. But while dozens of birds have been brought to rescue stations covered in oil, the vast majority will die out at sea far from human eyes and snapping cameras, according to Sharon Taylor a vet with the US Fish and Wildlife Service.
BP and the Perilous Voyage of Bama the Manatee
(05/23/2010) To the degree that Americans are paying attention to the environmental plight of marine wildlife in the Gulf of Mexico, they may focus most upon dolphins and whales. However, the U.S. public is much less familiar with another marine mammal, the manatee, which could also be placed in jeopardy as a result of the BP oil spill. One of the most outlandish creatures on the planet, the shy and retiring manatee, which gets its name from an American Indian word meaning "Lady of the Water", is one of my favorite animals.
Wildlife death toll from BP oil spill likely includes dolphins
(05/13/2010) The oil spill in the Gulf of Mexico is taking its toll on the region's wildlife: brown pelicans, sea turtles, several species of fish, and now dolphins have been found dead. The National Marine Fisheries Service reported today finding six dead dolphins in Louisiana, Mississippi, and Alabama since May 2nd. Officials are saying the deaths could be related to the oil spill or may be due to natural deaths from calving. They are currently testing tissue samples to determine if oil pollution was a cause of death. Dolphins have been observed swimming in oil-stained waters off of Louisiana.
Killer whales split into three separate species
(04/25/2010) Using genetic evidence scientists have discovered that the world’s killer whales, also known as orcas (Orcinus orca), likely represent at least three separate species.
New report finds millions of marine turtles killed by fisheries, not thousands
(04/06/2010) Humankind's appetite for seafood has had a bigger impact on the world's marine turtles than long thought. A new report by Conservation International (CI) in partnership with Duke University’s Project GloBAL (Global By-catch Assessment of Long-lived Species) finds that in the past eighteen years it is likely millions of marine turtles have been killed as bycatch by the world's fisheries.
Polar bears are newcomers on the world stage
(03/01/2010) One of the most well-known animals, the polar bear, is a newcomer on the world stage, according to research published in the Proceedings of the National Academy of Sciences. By studying the DNA of an ancient polar bear jawbone uncovered in 2004 in Norway scientists have for the first time pinpointed the time when the polar bear split from its closest relative, the brown bear. "Our results confirm that the polar bear is an evolutionarily young species that split off from brown bears some 150,000 years ago and evolved extremely rapidly during the late Pleistocene, perhaps adapting to the opening of new habitats and food sources in response to climate changes just before the last interglacial period."
Galapagos fur seals exploit warmer waters to establish colony off Peru
(02/25/2010) As suggested by their name, the Galapagos fur seals were once endemic to the Galapagos island chain off the coast of Ecuador. But in a warming world species are on the move, and the Galapagos fur seal is no exception. According to a recent story in Reuters the Galapagos fur seals have established what appears to be a permanent colony off the coast of Peru, 900 miles from their home.
Extinct animals are quickly forgotten: the baiji and shifting baselines
(02/23/2010) In 2006 a survey in China to locate the endangered Yangtze River dolphin, known as the baiji, found no evidence of its survival. Despondent, researchers declared that the baiji was likely extinct. Four years later and the large charismatic marine mammal is not only 'likely extinct', but in danger of being forgotten, according to a surprising new study 'Rapidly Shifting Baselines in Yangtze Fishing Communities and Local Memory of Extinct Species' in Conservation Biology. Lead author of the study, Dr. Samuel Turvey, was a member of the original expedition in 2006. He returned to the Yangtze in 2008 to interview locals about their knowledge of the baiji and other vanishing megafauna in the river, including the Chinese paddlefish, one of the world's largest freshwater fish. In these interviews Turvey and his team found clear evidence of 'shifting baselines': where humans lose track of even large changes to their environment, such as the loss of a top predator like the baiji.
