This "Yeti Crab" has not been previously encountered in 30 + years of hydrothermal vent exploration. One of the most important conclusions of such study is that today’s yeti crabs are likely descended from a common ancestor that lived in deep sea hydrothermal vents on mid-ocean ridges in the South East Pacific, between 30 and 40 million years ago. Scientists have also seen the animals feeding on mussels from the seafloor.

There is another undescribed species of yeti crabs from vents on the South West Indian Ridge.All the known species of yeti crabs are distributed in the southern hemisphere throughout the oceans bordering Antarctica. However, in 2000 a study was published on a fossil of more than 100 million years of existence, which is now known to be related to the yeti crabs. On the other hand, there are several scientists who claim that yeti crabs are carnivores, because they have a stomach similar to other species of crabs which suggests that they can also feed on fragments of algae or other microorganisms that reach their deep habitats. That’s because the crab’s arms and legs are covered in hair! It is important to point out there are other places in the deep sea that have similar conditions than those of vents and seeps; especially those where the remains of other animals such as dolphins, whales, sharks even wood are found. His name was granted in honor to the goddess of Polynesian myths, which was called Kiwa. Hop into a submarine and head for the floor of the Pacific!

The hot springs, fumaroles and geysers can be listed as the most common hydrothermal vents on earth. They employ chemical energy from the sea floor instead. The final results indicate that such creatures may be more vulnerable to the effects of human resource exploitation and climate change than what we usually think. An international team of scientists recently announced the discovery of a new species of blind deep-sea crab whose legs are covered with long, pale yellow hairs. The researchers showed a detailed genetic analysis of the yeti crabs, featuring all known species for the first time and revealing many aspects about their evolution. However, it is not a true crab.

They were discovered by a set of marine biologists who were using a submarine to study the ocean floor. Scientists have named the new family Kiwaidae. The bacteria get energy from the inorganic gases of the methane seeps, which are sites on the ocean floor that expel methane and hydrogen sulphide gas. Investigators have determined that most of the setae have clusters of chemosynthetic, sulfide-oxidizing bacteria living on them. Moreover, they have a very important adaptation – greatly enlarged gill chambers that improve respiration. They live as far south as the waters of the South Ocean near Antarctica.

This crab was first observed in March 2005 by marine biologists using the research submarine Alvin to explore hydrothermal vents along the Pacific-Antarctic ridge, south of Easter Island. The reasons for this situation are not totally clear, but it is speculated that the changes in the sea oxygen levels as a consequence of climate change are the main reason.
