What is fish with crab claws?

There is no species of fish with crab claws, as these are two distinct types of animals. Fish belong to the aquatic vertebrate group and have fins, gills, and scales, while crabs are crustaceans with exoskeletons, claws, and gills.

However, there is a species of Crab known as the Stone Crab (Menippe mercenaria), which is commonly harvested in Florida and the Gulf of Mexico waters. The Stone Crab is often confused with a type of fish due to how it is caught. When fishermen trap these crabs, they take only one of the creature's two claws and then throw it back to regrow the lost limb. The crab's claws are then sold in restaurants as a delicious delicacy that tastes similar to lobster.
