Florida Stone Crab
Menippe mercenaria
The Florida Stone Crab is a powerful native crab recognized by heavy claws with dark tips and its unusual claw-only fishery.
Florida Stone Crabs inhabit coastal and estuarine waters on both sides of the peninsula, with a major fishery in South Florida and the Keys.
Legal harvest removes qualifying claws and returns the living crab to the water. Survival and claw regeneration depend on correct handling and current harvest rules.
