Labrus falcatus Linnaeus, 1758

The permit, Trachinotus falcatus, is agame fish of the westernAtlantic ocean belonging to theCarangidaefamily. Adults feed oncrabs,shrimp, and smallerfish. Twosubmarines of theUnited States Navy were namedUSS Permit in its honor, in keeping with the “denizens of the deep” theme of submarine names that prevailed before the 1971 naming ofUSS Los Angeles.


The permit was first described by the “father of taxonomy”,Carolus Linnaeus in histenth edition of the work Systema Naturae, which was published in 1758. He originally classified it as Labrus falcatus though the fish has since been placed under the genus Trachinotus.[1]


The permit’s genus name, Trachinotus comes from a fusion of the Greek words trachys (τραχύς), which means “rough”, and noton (νωτον), meaning “back.”[2] Thespecies name for the permit, falcatus, is a Latin adjective, which roughly means “armed withscythes.” This serves as a reference to the permit’sdorsal fin that occasionally protrudes from the water whenschools of permit feed near the surface.[1]

Anatomy and morphology (fish)_2A preserved Permit from the Gulf of Mexico.

Permits can be distinguished by their elongateddorsal fins andanal fin.[1] The dorsal fin is shaped like a scythe. Permit tails are also deeply forked, and their bodies are compressed laterally, making the fish tall and thin when viewed from the front.[1]

The average permit has six to seven dorsalspines, and eighteen to twenty one soft rays. The anal fin has two to three spines, and sixteen to eighteen soft rays.[3] Both dorsal and anal fins have dark, anteriorlobes.[4] Permits have noscutes and have a large, orange-yellow patch on their abdomens in front of their anal fins, while theirpectoral fins are dark[5]

The Permit fish can reach a maximum length of 48 inches (122 cm) and can weigh up to 79 pounds (36 kg), according to the Florida Museum of Natural History

Distribution and habitat

Permit are usually found in shallow, tropical waters such asmudflats,channels, and muddy bottoms.[1] They are usually seen as individuals or in small schools; if approached when alone, they attempt to escape human interaction, but if approached when in a school formation, they become aggressive and can deliver dangerous bites.[3] Although permit are found close to shore and even in somebrackish areas, they spawn offshore.[4] Young Permit are found usually in thesurf zone where there are plenty of smallinvertebrates for them to feed on.

Permit are found in the western Atlantic ocean fromMassachusetts toBrazil, including most of theCaribbean islands.[3]
