9. Kiwa Crabs
Also known as yeti crabs, they live near the hydrothermal vents and are mostly known for their very hairy arms. They actually feed on the bacteria found near the vents, which it catches in the fine hairs on its arms. Scientists discovered that it waves its arms back and forth near the vents in order to get a good catch of bacteria to eat.
A kiwa crab is only about 5 to 6 inches long, so these animals are pretty tiny. It is a common belief that they’re blind. This sea creature is part of a family called “squat lobster,” which is a type of crustacean with a flattened body and long tails that are held underneath the thorax.
