Marine species suggest Antarctic "cradle of life"
By Maggie Fox, Health and Science EditorWed May 16, 1:30 PM ET
Carnivorous sponges, 585 new species of crustaceans and hundreds of new
worms have been discovered in the dark waters around Antarctica,
suggesting these depths may have been the source of much marine life,
European researchers reported on Wednesday.
The team, who scooped samples from as deep as 20,000 feet , found
unexpectedly rich diversity of animal life.
Many belong to species found around the world, notably in the Arctic,
while others appear to be unique to the deepest Antarctic waters, the
researchers reported in the journal Nature.
The unique species tend to be the kind that do not spread easily, which
suggests the deep, cold southern oceans may have been the source of many
types of marine life, the researchers conclude.
"The Antarctic deep sea is potentially the cradle of life of the global
marine species. Our research results challenge suggestions that the deep
sea diversity in the Southern Ocean is poor," said Angelika Brandt of
the Zoological Institute and Zoological Museum at Germany's University
of Hamburg.
"We now have a better understanding in the evolution of the marine
species and how they can adapt to changes in climate and environments,"
Brandt, who led the expedition, said in a statement.
Among the new creatures they documented are a gourd-shaped carnivorous
sponge called Chondrocladia; free-swimming worms and 674 species of
isopod, a diverse order of crustaceans that includes woodlice, also
commonly called pillbugs, sea lice or sea centipedes.
Of the isopod crustaceans, 585 species had never been seen before.
Between 2002 and 2005, researchers sampled water and the sediment from
2,500 to 20,000 feet in the deep Weddell Sea and adjacent areas.
Their catch was surprisingly rich.
"What was once thought to be a featureless abyss is in fact a dynamic,
variable and biologically rich environment," Katrin Linse, a marine
biologist from the British Antarctic Survey, said in a statement.
The researchers said the Weddell Sea is an important source of deep
water for the rest of the ocean. Species can enter the depths of the
Weddell sea from shallower continental shelves.
Animals that spread easily, such as the single-celled Foraminifera, were
similar to those found in other oceans.
"The isopods, ostracods (seed shrimp) and nematodes, which are poor
dispersers, include many species currently known only from the Southern
Ocean," the researchers wrote.

The extremes - like those volcanic sea vents and now the cold
Antarctica depths - seem to foster much life.

For an inappropriate notion of exciting apparently.

That depends on the inhabitants.
If the inhabitants were merely protozoa or amoeba, then the exiles would fit
in quite nicely as 'food'.
If the inhabitants were super-intelligent sentient beings, they could use
the exiles as laboratory 'rats'.
If the inhabitants were of our level of intelligence, it would at least give
them a good laugh for a while.
They could forward the exiles somewhere else when they got fed up with them.

I don't know about the weight limit, but you can bring all the liquid
products that you want, and you don't even have to take off your shoes.

Nah. If they tested them they would flunk.

They could have their own wing at the zoo.

Good then they'd get the blame.

Oddly, the restaurants (using the term loosely :-) )in my area don't
