New species of yeti crab has fiberglass mesh cloth

A new varieties of fiberglass mesh cloth yeti crab, exactly the third recognized to science, was discovered the first time inside cold waters of Antarctica, living in a harsher environment and clustered more closely together than its relatives.

White, hairy Kiwa tyleri, ranging in proportions from under an inch to 6 inches, were found living over each “like beans in a very jar” in 8,500-feet of water near hydrothermal vents of the East Scotia Ridge, as outlined by a work released Wednesday by PLOS ONE, and chronicled by National Geographic.

“We knew immediately that people’d found something tremendously novel and unique in hydrothermal vent research,” Sven Thatje, case study leader on the University of Southampton within the U.K., told National Geographic.

The living arrangements are not like that regarding the yeti crabs first discovered in 2005 (Kiwa hirsuta) and 2006 (Kiwa puravida). National Geographic explains exactly what called the Goldilocks Zone:

Waters near fiberglass mesh cloth East Scotia Ridge are usually just above freezing. However, the liquid spewing outside the vents themselves is superhot, which enable it to exceed 700 degrees Fahrenheit (about 400 degrees Celsius).

As the water cools rapidly away from the vents, K. tyleri has only a tiny, Goldilocks-like space where it may survive. Too close to the vent and in addition they fry. Too far away and so they freeze.

Subsequently, Thatje says the Antarctic yetis cluster together considerably more closely than the other two known species. He observed them along with the other, “like beans in the jar, filling every available space”—some 700 specimens per 11 sq ft (a square meter).
Andrew Thurber, an ocean ecologist from Oregon State, the Antarctic yeti crab “an extremely amazing discovery,” especially since nobody knew these animals existed a decade ago.

“It really identifies how little we still know,” Thurber told National Geographic, “and how most of these new species could possibly be additional widespread than we fiberglass mesh cloth thought.”
