It is easier to see the zigzagging tracks of the ghost crab than to spot the animal itself, which can scurry sideways so quickly it seems to disappear. Ghost crabs live on the beach, burrowing into the sand for protection and safety. Farther inland, it is the land crab, or white crab, that dominates. These large, whitish crabs have one claw larger than the other, and are sometimes eaten. Another very common crab is the hermit crab. Although associated with the sea, these crabs are found miles away from the shore, and high up on mountainsides. Many take up residence in the West Indian top snail shells. When hermit crabs outgrow their shells, they have to find new ones. Hermit crabs will eat just about anything, including rat poison, carrion, and feces. Their flesh is a traditional fish bait.
