The researchers found that the crabs probably existed in large regions of mid-ocean ridge in the Eastern Pacific, but they are now extinct in those areas.
What ocean do yeti crabs live in?
The crustaceans were found near the Pacific-Antarctic ridge, south of Easter Island, along hydrothermal vents. At just less than six inches long, yeti crabs have beefy and compact bodies to help them adapt to the highly competitive life on the seafloor.
Is there a yeti crab?
Kiwa hirsuta is a crustacean discovered in 2006 in the South Pacific Ocean. This decapod, which is approximately 15 cm (5.9 in) long, is notable for the quantity of silky blond setae (resembling fur) covering its pereiopods (thoracic legs, including claws). Its discoverers dubbed it the “yeti lobster” or “yeti crab”.
What’s the average length of a yeti crab?
The water depth and temperature is also a contributing factor to differences between the species. As all are deep-sea dwellers, the conditions are mostly dark and very cold with warmer water coming from the hydrothermal vents creating the habitat for these creatures to live. The average length of the yeti crab is 15 centimeters.
Where did the yeti crab get its name?
(1) The Yeti Crab or Kiwa hirsuta was discovered as late as 2005 on a hydrothermal vent along the Easter Island. They are related to the hermit crabs which are common. (2) The name Kiwa comes after the goddess of shellfish in Polynesian mythology.

Why are the claws of a yeti crab so important?
