The family Rachycentridae contains a single genus, Rachycentron, of which there is a single species, Rachycentron canadum.
The single member of this family is often referred to as a Cobia, however other common names include Black Kingfish, Black Salmon, Ling and Lemonfish.
The family Rachycentridae resembles its close relatives, the remoras of the family Echeneidae, however they lack the remora's dorsal sucker and have a more stout body.

Cobias are swift-moving, voracious, predatory fish growing up to 1.8 m in length. The lower jaw protrudes beyond the upper jaw and the head is rather flat. This is a dark coloured fish with brown sides, each with two long brown stripes. The belly is often a lighter brownish, yellowish colour.
The distinctive dorsal fin, with several short spines and a long, soft ray, together with the horizontally carried pectoral fins and long upper tail fin lobe give this species the profile of a shark.
Cobias feed on crabs, fishes and squid, and are often found over sand and rubble reef bottoms or in small schools accompanying whale sharks, or other large marine animals such as large rays.
