The roosterfish is a unique species of marine carangiform fish found in the warmer shallow waters of the southeastern Pacific Ocean, from Baja California south to Peru. Roosterfish are a popular sport fish for being strong fighters. They are also important targets of local artisanal and subsistence fisheries. It is the only species in the genus Nematistius, the family Nematistiidae, and the suborder Nematistioidei. Their name comes from them having a "rooster comb" or seven long spines on the dorsal fin. Roosterfish can reach over 1.6 m in length and over 50 kg (110 lb) in weight.
