Oplegnathidae is a family of marine fish within the Perciformes commonly known as knifejaws; some species are known as beakfish. It contains a single genus, Oplegnathus. The largest, the Cape knifejaw, can reach a maximum length of about 90 cm (35 in). Knifejaws have teeth fused into a parrotlike beak in adulthood. They feed on barnacles and mollusks, and are fished commercially. They are found in the north-western Pacific Ocean (e.g. Japan), in the southern half of Australia, in the Galapagos, Peru, and Chile, and in Southern Africa.
