Trachinotus falcatus

The permit, Trachinotus falcatus, is a game fish of the western Atlantic Ocean belonging to the Carangidae family. Adults feed on crabs, shrimp, and smaller fish. Two submarines of the United States Navy were named USS Permit in its honor, in keeping with the "denizens of the deep" theme of submarine names that prevailed before the 1971 naming of USS Los Angeles.
