Yeti Crab's were discovered 4 1/2 years ago, and live at the very-very bottom of the sea. Very few will see this creature unless they can withstand 300,000 degrees of air pressure pushing them on all sides. Because of this, they use special submarines called Deep-Cam Submarines that film creatures in areas humans cannot reach. These Yeti Crabs are crabs that are egg white and covered in hair that isn't hair, but rather False-Fur , which is a different type of ivory-containing soft stuff. Hair is only on mammals. Other then that they are completely normal crabs.
