The roosterfish, Nematistius pectoralis, is a game fish found in the warmer waters of the East Pacific from Baja California to Peru.[1] 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; its 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 predominantly inhabit shallow waters, where a substantial portion of their time is allocated to the region between the sea surface and depths of up to 15 meters.[4]

Roosterfish can reach over 1.6 m (5 ft 3 in) in length and over 50 kg (110 lb) in weight.[5] 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. Catch and release is strongly recommended.
