(11/19/2007) Only 150 individual vaquita, the world's smallest cetacean, remain, according to a new study published in conservation Biology. The species has been decimated as accidental bycatch in fishing nets in its Gulf of California habitat. Researchers--who say there may be only a two-year window to save the species from extinction--have launched a last-ditch conservation effort.

Rare Chinese river dolphin sighting in doubt
(09/01/2007) A prominent researcher is skeptical of last week's reported sighting of the baiji, the Chinese river dolphin declared extinct earlier this year, according to the New York Times. The sighting near Tongling city in Anhui Province -- widely reported in Chinese and Western media -- was captured on video.
Saving beautiful - and ugly - species from extinction
(08/30/2007) Allow me to wax poetic about the world's newest wildlife organization, EDGE. I must admit I'm a little in love. This singular organization was founded in January as a part of the London Zoological Society. Its basic tenants remain similar to other endangered species programs: survey populations, set up conservation programs, work with local governments and communities to ensure protection. However, what is unique about EDGE is not their approach to saving species, but rather the species they choose to focus their efforts on. This year they have selected ten mammalian species: the Yangztee River Dolphin, Attenborough's Long-Beaked Echidna, Hispaniolan Solenodon, Bactarian Camel, Pygmy Hippopotamus, Slender Loris, Hirola, Golden-rumped Elephant Shrew, Bumblebee Bat, and the Long-eared Jerboa.

Extinction of the Yangtze river dolphin is confirmed
(08/08/2007) After an extensive six-week search scientists have confirmed the probable extinction of the baiji or Yangtze river dolphin. The freshwater dolphin's extinction had been reported late last year.
U.S. court blocks sonar testing to protect whales
(08/07/2007) A U.S. federal court blocked the Navy from using a type of sonar that environmentalists say pose a threat to whales off the coast of California. The judge noted that the Navy's own analyses concluded that the Southern California exercises "will cause widespread harm to nearly thirty species of marine mammals, including five species of endangered whales, and may cause permanent injury and death" and characterized the Navy's proposed mitigation measures as "woefully inadequate and ineffectual."
How to save the world's oceans from overfishing
(07/08/2007) Global fishing stocks are in trouble. After expanding from 18 millions tons in 1950 to around 94 million tons in 2000, annual world fish catch has leveled off and may even be declining. Scientists estimate that the number of large predatory fish in the oceans has fallen by 90 percent since the 1950s, while about one-quarter of the world's fisheries are overexploited, depleted, or recovering from depletion. Despite these dire trends, the situation is changing. Today some of the world's largest environmental groups are focused on addressing the health of marine life and oceans, while sustainable fisheries management is at the top of the agenda for intergovenmental bodies. At the forefront of these efforts is Mike Sutton, director of the Monterey Bay Aquarium's conservation program: the Center for the Future of the Oceans. The aquarium, which has long been recognized as one of the world's most important marine research facilities, is pioneering new strategies for protecting the planet's oceans. Sutton says the approach has four parts: establishing new marine protected areas, pushing for ocean policy reform, promoting sustainable seafood, and protecting wildlife and marine ecosystems.
Harpoon proves whale is 115-130 years old
(06/12/2007) A 19th-century weapon found in the neck of a 50-ton bowhead whale caught off Alaska shows that cetaceans can live more than 100 years, reports the Associated Press (AP).
South Korea fishermen cheat on whale killing
(05/09/2007) Fishermen in South Korea are killing far more whales than they claim, reports an article in New Scientist Magazine. DNA fingerprinting of whale meat purchased in local markets suggests that South Korea caught 827 minke whales between 1999 and 2003, well above the 458 they reported.
Japan will kill 50 humpbacks
(04/26/2007) Humpback whale populations are rebounding but concerns are rising over Japan's plans to kill 50 humpback whales for "scientific" research, reports a paper published in the latest issue of Science.
The news of extinction: western media's response to the demise of the Baiji
(04/01/2007) The news came and went with an alacrity that I found alarming, almost jolting. I waited for weeks, faithfully; I could not believe that the initial announcement would be followed by nothing but silence on the issue, no rationalizations, no opinions, no discussions, no outpourings of grief. Just silence.
Jumbo squid and sperm whales tagged
(03/08/2007) Scientists have simulatenously tagged sperm whales and jumbo squid off Mexico's Pacific coast, allowing them to be tracked by satellite even as they dive to depths exceeding 3000 feet. Details of the effort are published in in the March 12 edition of the journal Marine Ecology Progress Series (MEPS).
China will continue search for 'extinct' baiji river dolphin

Goodbye to the Baiji
(12/14/2006) After a short illness spurred by pollution, overfishing, boat traffic, and obstructions like dams, the Baiji was declared 'functionally extinct' last night. As a species, the river dolphin found only in China's Yangtze River was 20 million years. The Baiji is survived by other river dolphins, all themselves threatened, in the Ganges, Indus, Amazon, Orinoco, and La Plata rivers. No memorial service will be held.
The Vaquita, the world's smallest cetacean, dives toward extinction

Chinese river dolphin nearly extinct says official
(12/03/2006) Xinhua, China's state news agency, reported that a 26-day search for the Baiji, or the Yangtze dolphin, found no dolphins. The Baiji is highly threatened by pollution, overfishing, and obstructions like dams.
How many whales are enough?
(11/30/2006) Iceland's decision to resume hunting endangered fin whales raises an important question: how many whales are enough to sustain a population? While conservionists will debate over the actual number using varying models and population studies, a new paper published in the journal Bioscience attempts to establish a new system for setting population targets for threatened species.
Whales share human brain cells
(11/27/2006) Whales share brain cells with humans according to a new study published online November 27, 2006 in The Anatomical Record, the official journal of the American Association of Anatomists. The research suggests that "certain cetaceans and hominids may have evolved side by side."
Grey whales missing from traditional feeding grounds
(10/23/2006) Researchers found few grey whales in their traditional feeding grounds in the North Pacific last summer according to a scientist at the University of Bath. Dr. William Megill, a professor of mechanical engineering with special interest in biomimetics at the University of Bath, said that the absence of the 17,000 grey whales from traditional summer feeding grounds in the North Pacific could be cause for concern, despite the species' recent removal from the endangered species list.
Dolphin Slaughter Resumes in Japan
(09/21/2006) As the annual dolphin drive hunts begin in the Japanese villages of Taiji and Futo, a consortium of scientists and zoo and aquarium professionals has launched a campaign to end the practices through public awareness and by appealing to the government of Japan to put an end to the hunts.
Ancient blue whale was a shark killer
(08/22/2006) A 25-million-year-old whale fossil from southeastern Australia suggests a curious origin for baleen whales. Presented at the at the Melbourne Museum last week, the fossil shows that earliest baleen whales were small, toothed and highly predatory creatures with enormous eyes -- virtually the opposite of the baleen whales we know today. These, like the blue whale and the humpback are gentle, toothless giants that feed on krill and other tiny organism.
Norwegian killer whales most toxic mammals in Arctic
(12/12/2005) Initial scientific results show Norwegian killer whales are the most toxic mammals in the Arctic, says WWF, the global conservation organization. Previous research awarded this dubious honour to the polar bear, but a new study shows that killer whales have even higher levels of PCBs, pesticides and a brominated flame retardant.
Underwater sound pollution threat to marine life says new report
(11/21/2005) New evidence shows that the rising level of intense underwater sound produced by oil and gas exploration, military sonar and other manmade sources poses a significant long-term threat to whales, dolphins, fish and other marine species, according to a report published today by the Natural Resources Defense Council (NRDC).
