The yeti crab is so unusual that a whole new family of animal had to be created to classify it.
Why do they need the hairy-like arms?
- to filter toxic minerals spewing forth from the vents (below on the vents)
- catch food and minerals
- sensors to help the blind animal find a mate
A hydrothermal vent is a crack in a planet’s surface from which earth (geothermal) heated water comes out. These vents can be on land as hot springs and geysers, or under water.
Submarine hydrothermal vents are a fascinating, biologically productive, marine habitat. The fumes host many bacteria and plancton like microbes that are the food base for giant tube worms, clams, limpets, shrimp, and our yeti crab.
