The New Species Yeti Crabs, Bacteria Breeders

Scientists discover unique species of crabs on the ocean floor off the coast of Costa Rica. Hair that grows in the claws of these animals into the breeding barn of bacteria as well as food for crabs.

These marine animals called yeti crabs. So called because the entire arm covered with thick hair crab-like creatures legendary yeti. Yeti crabs is still a family with a bushy-haired crab Kiwa hirsuta, which was found in 2005 near Easter Island.

"It was shocking. Crabs are many. The size is not too small," said Andrew Thurber, marine ecologist at Oregon State University in Corvallis.

Yeti Crabs proposed name Kiwa puravida. In the language of Costa Rica, a name that means "pure life".

Thurber was accidentally found the yeti crabs when it undertook an expedition to study the seepage of methane and hydrogen sulfide on the seabed. At the time crawling on the seafloor, the research vehicle they found a 9-inch crab waving above the methane seepage.

Hair that grows on the crabs claw turns out to be a place to live bacteria. Organic gas seepage into the source of bacterial food. Crabs that have trunks with a comb-like edge to harvest the bacteria.

In order for bacteria to grow more rapidly, crab claws waving above the methane seepage. Thus, the bacteria get a supply of oxygen and sulfur in the correct amount.

This finding confirms, yeti crabs get their energy from chemicals in the ocean, not from the sun. *** [NATURE | ANTON WILLIAM | KORAN TEMPO 3728]
