New Jersey Scuba Diving

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.
