description Sand Fiddler Crab Overview
The sand fiddler crab is a small intertidal crab of the fiddler-crab group, commonly associated with sandy beaches, tidal flats, and salt-marsh margins along the Atlantic coast of North America. Males have one greatly enlarged claw, which they wave during courtship and territorial displays, while the other claw remains small and is used in feeding. Individuals excavate burrows in sediment and feed by sorting organic particles from sand or mud.
