Yeti Crab (Kiwa hirsute), is a species, which belong to the Kiwaidae family of the crabs and have been recently discovered in 2005. This species looks like an Egyptian scarab but it has two giant hairy arms, and these arms support its two white claws.
These creatures are about 6 inches in length. They look frightening due to their fur like silky blond setae, which covers their legs and claws. The sea animals has eyes, which lack pigment and thus it is considered that this species is perhaps blind. It has hair like structure on its pinchers and arms, and these are believed to be bacteria filters. The hairy pincers of these species contain filamentous bacteria and scientists are of the view that it is to detox the poison in the water, where these species live.
These species have been seen only in the South Pacific Ocean at a depth of around 2200 meters. It was seen from a submarine.
This creature is so new to us that scientists are not sure of what this creature eats. Though the scientists feel that these creatures are carnivorous they are of the view that this creatures feed on bacteria.
No information is available regarding the breeding or reproduction behavior of these species.
Story of Discovery of the Yeti Crab
The yeti crab has been first discovered by the international group of scientists in the March, 2005. This amazing species has been discovered using a sub-marine named as "Alvin". These species has hairy legs, so it is being nick named on the name of the fabled yeti, which used to be the snowman of the Himalayas. This amazing sea creature was discovered when a team led by Bob Vrijenhoek (the scientist of MBARI), were on their expedition to know about the bottom dwelling creatures and their relation to the hydrothermal vent. Marine biologist, Michel Segonzac of France was the first to notice this yeti crab on the sea floor. Later, it was found in the more dives made by Alvin and it was found that most of these species live at the depth of 2200 meters. Here, these creatures were hiding behind or underneath of the rocks but their hairy arms were visible. The scientists are yet unaware of the different characteristics and ecology of these species. While their expedition in the South Pacific Ocean, the scientists were surprised to note that how they fit into the hydrothermal-vent ecosystems and this is still a mystery for them. Some of the scientists also noticed that these species were feeding on the mussels. As these creatures' arms contain filamentous bacteria, the scientists are of the view that this creature might be farming these bacteria's for food. The scientists were also of the view that as these species are blind, they might be using their spines or hair like appearance as a sensor to for feeding and mating purposes. The mysteries in the sea are most vast than their size itself.
