In 2006, scientists discovered another new type of yeti crab in the deep waters of Costa Rica, searching for food in the sulfide-rich magma spewing out of hydrothermal vents in the deep ocean - just how is food produced and eaten?

Scientists have discovered that the crabs can cultivate bacteria on their claws, which they then eat as food.

The undersea creature is named for the bristly hairs that grow on its elongated pincers. They wield their large pincers at the spout, which in turn breeds a variety of nutritious bacteria on their bristles for consumption.

Researchers believe that the deep-sea yeti crabs consume large amounts of oxygen from their surroundings as they flail about at undersea vents, and large colonies of sulfurized bacteria thrive on their pincer hairs. And when they are hungry, they use a specialized tool on their mouths like a comb to comb the bacteria off the hairs and send them into their mouths for digestion and absorption.
