Black jellyfish, strange marine species discovered in deep ocean

A 1-cm long larval squid, photographed through Russ Hopcroft’s microscope.



This lovely red medusa, Atolla gigantea, about 15 cm in diameter, was collected in midwater by the ROV and photographed in the bigger kreisel. When a species like this is caught with a net, the soft gelatinous tissue is shredded by the net fabric or squashed by other captured animals and the tentacles are torn off. This beautiful red color is common among mesopelagic 'jellies' because it isn't visible in the perpetually dark water, yet it masks any bioluminescence emitted by prey inside the pigmented predator’s gut.



A jellyfish in the genus Aequorea swims in the planktonkreisel. A bluewater scuba diver caught this 50 mm diameter medusa in a plastic jar and carried it back to the ship's lab for study.

An expedition to an unexplored deep ocean basin south of the Philippine Islands has turned up a trove of previous undiscovered species including a black jellyfish, a transparent sea cucumber, and a tentacled worm that resembles a squid.

The project, backed by the Woods Hole Oceanographic Institution, National Geographic, and the National Oceanic and Atmospheric Administration (NOAA), used a remote-operated vehicle to survey the Celebes Sea -- the center of one of the most biologically diverse marine areas -- at a depth of more than 9,100 feet (2,750 m). More than two dozen scientists were involved in the project. A report is expected in November.

Dr. Larry Madin, chief scientist for the expedition, called the expedition a success.

"We had made the first use of a deep ROV in the Celebes Sea, and perhaps in all of the Philippines," he wrote on the expedition's blog. "We found fascinating animals, some familiar, some possibly new. We put together from all our samplers a pretty complete picture of the variety of zooplankton, fishes and benthic creatures of this area."

The researchers hope their findings will stimulate more extensive exploration and research in the region.

Species discovery news

Census of marine life opens with 122,000 species
(7/1/2008) Discovering a new species can be the highlight of a biologist's career. Yet once a species enters the formal literature, complications may develop. The systen has been especially problematic because for centuries biologists have lacked the tools to construct a full and flexible list of the world's innumerable species. Using the Internet and hundreds of scientists around the world, the Census of Marine Life is attempting to take on this monumental task.

Quick biological surveys are facilitating conservation efforts
(6/9/2008) Short but intense biological surveys in remote parts of the world are playing a critical role in determining conservation priorities and disseminating information to policy makers and stakeholders, said researchers speaking in a series of presentations at a scientific conference held in Paramaribo, Suriname.

Scientists aim to catalogue tropical island from mountaintops to seafloor
(6/4/2008) Scientists are launching an effort to catalogue a complete tropical ecosystem, the first time anyone has attempted such an ambitious undertaking. Led by researchers at the University of California, Berkeley, a U.S.-French team plans to collect DNA "barcodes" for every animal, plant, and fungus on the small island of Moorea in the South Pacific, scouring habitats from coral reefs to high-reaching cloud forests. The island could eventually serve as a model for how ecosystems respond to stresses such as climate change, invasive species, and pollution.

50 species per day discovered in 2006
(5/27/2008) 16,969 species were discovered in 2006 according to a report compiled by Arizona State University's International Institute for Species Exploration, the International Commission on Zoological Nomenclature, the International Plant Names Index, and Thompson Scientific.

Naming rights for newly discovered 'walking frog' to be auctioned for conservation
(5/20/2008) The Amphibian Ark, an initiative to save disappearing amphibians from extinction, will auction of the naming rights of a newly discovered 'walking frog' in Ecuador to raise money for local conservation efforts.
