Coenobita clypeatus

The Caribbean hermit crab is a species of land hermit crab native to the west Atlantic, Bahamas, Belize, southern Florida, Venezuela, the Virgin Islands, and the West Indies. Adults burrow and hide under the roots of large trees, and can be found a considerable distance inland. As with other terrestrial crabs, they use modified gills to breathe air. Their shells help maintain the humidity necessary for gas exchange to function.
