Marine census reveals ‘Jurassic shrimp’ and more

10 December 2006

Catherine Brahic

The 2006 Census of Marine Life is in, and this year’s trawl includes scores of weird and wonderful creatures brought back from the deep.

The latest census has revealed 500 new species.

One is the shrimp-like Phronima. It was found 5000 metres below the surface of the Sargasso Sea, along with hundreds of related species.

All were eating each other and the organic matter that falls from the surface waters in drifts of “marine snow”.

Another find is the Neoglyphea neocaledonica – nicknamed the “Jurassic shrimp” by its discoverers.

It was thought to have disappeared 50 million years ago.

And it was not just individual creatures that caught the eyes of the researchers.

Thanks to a new sensor, they also spotted a colossal school of 8 million fish off the coast of New Jersey, US. The shoal was the size of Manhattan island in New York City.

The researchers also shot deep-sea video, for example this footage of hydrothermal vents (.mov format) in the North Pacific and North Atlantic [UPDATE 2008: link not working any more].

It features the Pompeii worm, seen in shimmering hot waters – it is thought to be the most heat-resistant creature on Earth. …

2006 is the census’s sixth year of existence and will run till 2008. The results will then be analysed from 2009 to 2010.

The researchers intend the end result to be a full description of what lived, lives and will live in the oceans.

“Each expedition reveals new marvels of the ocean – and with the return of each vessel it is increasingly clear that many more discoveries await marine explorers for years to come,” says Fred Grassle, chair of the project’s scientific steering committee.

In 2006, the 2000 researchers from 80 countries led 19 marine expeditions, with a 20th underway in the Antarctic.

They also used satellites to track more than 20 species including sharks, sea lions, albatross and squid.

  1. Life thrives at searing sea vent, under ice: report
    3:02PM today

    By Alister Doyle, Environment Correspondent

    OSLO (Reuters) – Marine creatures are thriving by a record hot volcanic vent in the Atlantic and in dark waters under thick Antarctic ice, boosting theories that planets other than Earth are suitable for life, scientists said on Sunday.

    About 150 new types of fish were among 500 new marine species, including furry crabs and a lobster off Madagascar, found in the seas in 2006, according to researchers in the 70-nation Census of Marine Life.

    Many species were found in places long thought too hostile for life — including by a vent spewing liquids at 407 Celsius (764.6F) and other habitats that were dark, cold or deep. Some places seemed as inhospitable as planets such as Mars or Venus.

    “The age of discovery is not over,” said Jesse Ausubel, a program manager at the U.S. Sloan Foundation which is a sponsor of the 10-year Census. Finds “are provocative for NASA and for people who are interested in life in places other than Earth.”

    Among discoveries in 2006 were shrimps, clams and bacteria living by the searing 407C vent on the floor of the Atlantic Ocean north of Ascension Island, the hottest sea vent ever documented and more than hot enough to melt lead.

    “This is the most extreme environment and there is plenty of life around it,” said Chris German, of Britain’s Southampton Oceanography Center and a leader of the Atlantic survey.

    He said one big puzzle was how creatures coped with shifts in temperatures — water on the seabed at 3,000 meters (9,842 ft) was just 2C yet many creatures withstood near-boiling temperatures of up to 80C from the thermal vent.


    German said it was a bit like a person agreeing to live in a blistering sauna and be hosed at random with freezing water.

    Scientists had not yet probed how hardy the microbes nearest the hottest part of the vent were — a type of bacteria called “Strain 121” found in the Pacific in 2003 holds the record by being able to withstand temperatures of 121 Celsius.

    And another expedition found crustaceans, jellyfish and single-celled animals living in darkness in the Weddell Sea off Antarctica under ice 700 meters thick and 200 km (125 miles) from open water. Most of those creatures were new to science.

    “You can think of it as a cave, one of the remotest caves on earth,” Ausubel said of findings by a robot camera.

    “Wherever we’ve gone on earth we’ve continued to find life,” German said. He said recent discoveries could be encouraging for the search for life elsewhere in the universe.

    Some experts speculate that Jupiter’s moon Europa could hide an ocean beneath its frozen surface and Ausubel noted life has been found on Earth beside subsea methane seeps — Saturn’s moon Titan also has methane. And NASA said last week it had found signs of liquid water on Mars.

    Among other 2006 finds by the census, due for completion in 2010, was a “Jurassic shrimp” in the Coral Sea east of Australia and previously thought extinct 50 million years ago.

    The biggest new species was probably a 1.8 kg (4 lb) rock lobster found off Madagascar. And a furry crab, also dubbed a “Yeti crab,” was found off Easter Island.

    In the longest migration ever documented, census researchers tracked sooty shearwater birds on a 70,000 km flight sweeping round the Pacific in 200 days, an average 350 km a day.


  2. Wow i didnt know you could discover that kind of shrimp that is very unususal. Great job discovering that !!!!!! Wow ! That is amazing keep finding more interesting animals for all to see ! I am astonished!
