The ghost crab is a generalist as it eats carrion, debris and smaller animals, such as clams, turtle hatchlings and other crabs. Ghost crabs mostly feed during the night.
The ghost crab is a semiterrestrial crustacean that lives on tropical and subtropical shores worldwide. The ghost crab's morphology is characterized by elongated eyestalks and a square, pale body that blends in with the surrounding sand. Additionally, one claw is slightly larger than the other although not to the extent of the fidder crab, a close relative. Ghost crabs are capable of changing color to blend with their environment, but this takes a longer time than most other color-changing animals.
