Thatje also said the newfound species is better built for climbing than its kin—since it has shorter and more robust front limbs. K. tyleri is also more stout and compact than its abyssal plain-loving cousins. This physique likely allows the crustacean to jockey for position on vents' vertical surfaces.

Where can I find yeti crabs?
Three Yeti crab species have been documented. Kiwa hirsuta was the first species to be discovered and is found in the Pacific-Antarctic Ridge. The species name hirsuta is the Latin word for “hairy.” The morphologically similar Kiwa tyleri lives in the coldest waters of any Yeti crab species, in the Southern Ocean. Scientists nicknamed it the “Hoff” crab because the bristles reminded them of the hairy-chested Baywatch actor, David Hasselhoff. The third species, Kiwa puravida, has only been found living near a vent off the coast of Costa Rica and is named for the Costa Rican saying “ pura vida ” that means “pure life.”
What is yeti crab?
A Yeti is a fabled creature with wild white fur, and these crustaceans have a striking white, fuzzy-looking external morphology, which resembles their beastly namesake. As they are crabs, this texture is certainly not fur, but instead bristles called "setae," which cover their "chelipeds" (claws). Yeti crabs are, of course, much smaller than a Yeti, growing to only about 15 cm/5.9 inches long. To add to this crab’s sensational namesake, the genus name Kiwa comes from Polynesian mythology. Kiwa alludes to a goddess of shellfish in Polynesian culture.
