A Caribbean hermit crab in theDry Tortugas National Park,Florida

TheCaribbean hermit crab(Coenobita clypeatus), also known as thesoldier crab,[2]West Atlantic crab,tree crab,orpurple pincher(due to the distinctive purple claw), is a species of landhermit crabnative to the westAtlantic,Belize,southernFlorida,[3]Venezuela,and theWest Indies.[4]

Description[edit]

Adults burrow and hide under the roots of large trees, and can be found a considerable distance inland.[3]As with other terrestrial crabs, they use modified gills to breathe air. Their shells help maintain the humidity necessary for gas exchange to function.[5]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.[2]

Ecology[edit]

Caribbean hermit crabs are both herbivorous and scavengers.[6]In the wild,C. clypeatusfeeds on animal and plant remains, overripe fruit, and faeces of other animals,[3]including theMona ground iguana(Cyclura stejnegeri).[2]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 againstpredators.[3]As with other species of hermit crabs,C. clypeatusmay engage in "shell fights" and can emit a chirping noise when stressed.[7]

Aquaculture[edit]

This species is one of the two land hermit crabs commonly sold in the United States as pets, the other being theEcuadorian hermit crab.[4][8]C. clypeatushas been confirmed to live as long as 12 years,[9]and some crab owners have claimed to have crabs live up to 40 years.[10]
