The Jonah crab (Cancer borealis) is a species of crab found on the Atlantic coast of North America. It is closely related to the Dungeness crab of the Pacific coast,and is known for its strong claws, although it is not a very aggressive species . The claws are so well muscled that they are generally prized as food over legs, which are more typically prized in other crab species. It has been fished on a small scale since the 1970s, with less than 1,500 tonnes being caught annually . In recent years its popularity has been growing.
