Stone crabs are found on the east coast, south of North Carolina and are most are commercially harvested in the Florida area. They have a very thick shell with large, black tipped claws and grow to about 5 inches wide. Government regulations prohibit commercial harvesting of whole crabs so only the claws are eaten. They have the ability to grow back a lost claw, so the fishermen twist off one of the claws and return the live crabs to the sea. The claw grows back after the crab molts once or twice.
