Caribbean Land Hermit Crab

Adults burrow and hide under the roots of large trees, and can be found a considerable distance inland. As with other terrestrial decapods, they use modified gills to breathe air. Their shells help maintain the humidity necessary for gas exchange to function. Typically, the Caribbean hermit crab's left claw is larger in size than its right claw and is purple in color. Female land hermit crabs release fertilized eggs into the ocean. The spawning (called "washing" in the English-speaking Caribbean) occurs on certain nights, usually around August.

Caribbean hermit crabs are both herbivorous and scavengers. In the wild, C. clypeatus feeds on animal and plant remains, overripe fruit, and faeces of other animals, including the Mona ground iguana (Cyclura stejnegeri). The West Indian top snail (Cittarium pica) shell is often used for its home, and the hermit crab can use its larger claw to cover the aperture of the shell for protection against predators. As with other species of hermit crabs, C. clypeatus may engage in "shell fights" and can emit a chirping noise when stressed.
