Beach Crabs
Ocypode quadrata
Uca spp
These small crabs are largely terrestrial. Female Fiddler Crabs lack the huge claw of the male, which is very strong but is used only in dance-like territorial displays. Several species in the area differ mainly by habitat. Fiddlers prefer marshes and stream banks, where huge colonies riddle the peat with tunnels near the waterline. Almost entirely terrestrial, you will find Ghost Crabs skittering across the beaches at night. Placed in the water, they may even drown! Both grow to a body size of approximately 1 inch.

These are all so-called "true crabs".
True crabs are crustaceans with extremely reduced tails, which are carried folded under the body. Males are generally larger than females. Presented here are just the most common of many local species. Sizes quoted below are body width. Hermit Crabs are listed elsewhere. They are not closely related.
