The roosterfish, Nematistius pectoralis, is a game fish found in the warmer waters of the East Pacific from Baja California to Peru. It is the only species in the genus Nematistius and the family Nematistiidae.[2][3] It is distinguished by its "rooster comb", seven very long spines of the dorsal fin.

The roosterfish has an unusual arrangement of its ears: the swim bladder penetrates the brain through the large foramina and makes contact with the inner ear. It uses its swim bladder to amplify sounds.

Roosterfish can reach over 1.6 m (5 ft 3 in) in length and over 50 kg (110 lb) in weight. The weight of the average fish hooked is about 20 lb (9.1 kg). The fish is popular as a game fish, but it is not considered a good eating fish.
