Oplegnathus fasciatus

Oplegnathus fasciatus, the barred knifejaw or striped beakfish, is a species of knifejaw native to the northwestern Pacific Ocean, though a smattering of records exists from other localities in the eastern Pacific such as Hawaii and Chile. It is an inhabitant of rocky reefs and occurs at depths from 1 to 10 m (3.3 to 32.8 ft). Juvenile members of this species can be found with patches of drifting seaweed. This species can reach a total length of 80 cm (31 in), with the greatest recorded weight for this species of 6.4 kg (14 lb). The color pattern consists of light and dark vertical bars from which it derives its name. It has been recorded as feeding on hard-shelled invertebrates such as crustaceans and molluscs. It is a commercially important species and is also farmed. It is also sought after as a game fish. A striped beakfish is the surviving specimen of five striped beakfish that endured more than 2 years in the partially submerged hull of the Japanese boat Sai-shou-maru. The striped beakfish made an appearance in the Animal Crossing franchise, under the name 'barred knifejaw'.
