A crab that grows its own food

A crab that grows its own food.

In the deep ocean off the coast of Costa Rica, scientists have found a species of crab that cultivates gardens of bacteria on its claws, then eats them. The yeti crab — so-called because of the hair-like bristles that cover its arms — is only the second of its family to be discovered. The first — an even hairier species called Kiwa hirsuta — was found in 2005 near Easter Island.
