They are brownish red with gray spots and a tan underside, and have large and unequally-sized chelae (claws) with black tips.
The Florida stone crab is usually fished near jetties, oyster reefs or other rocky areas, just as for blue crabs
Harvesting is accomplished by removing one or both claws from the live animal and returning it to the ocean where it can regrow the lost limb(s). To be kept, claws must be 2.75 inches (70 mm) long, measured from the tips of the immovable finger to the first joint. However, mortality rates are 47% for doubly-amputated crabs and 28% for single amputees.
