Spindly species found in ocean's crushing depths - Yahoo! News
PARIS (AFP) – Scientists unveiled on Wednesday a gossamer, ghostly creature discovered in the deepest reaches of the ocean between Indonesia and the Philippines.
The squidworm, up to 9.4 centimetres (3.7 inches) in length, is far more elegant than its name would suggest.
Swimming upright, it navigates by moving two body-length rows of thin, paddle-shaped protrusions that cascade like dominoes.
Ten tentacles as long or longer than its body stick out of its head, along with six pairs of curved nuchal organs that allow the squidworm to taste and smell underwater.
Using a remotely-operated submersible, a trio of marine biologists led by Karen Osborn of the of Oceanography in California found the previously unknown animals in the Celebes Sea at a depth of 2.8 kilometres (1.7 miles).
"I was really excited," Osborn said of her first glimpse. "It was so tantalising because the animal was so different from anything previously described, with the fantastic headgear."
Squidworms live about 100 to 200 metres above the , a layer rich in undiscovered fauna and flora, scientists say.
"I would estimate that when exploring the deep water column, more than half the animals we see are undescribed or new to science," Osborn said in an email.
Up to now, this region has been largely inaccessible because tools for collecting samples either scraped along the ocean floor, or mangled specimens so badly that they were useless or unrecognisable once brought to the surface.
The squidworm, Teuthidodrilus samae, does not appear to be a predator, feeding instead on bits of so-called "marine snow," a mix of sinking microscopic plants and animals, faecal material and cast-off mucus.
