Oplegnathus Insignis
''Oplegnathus'' is currently the sole recognized genus in the knifejaw family (Oplegnathidae) of marine centrarchiform ray-finned fishes. The largest, the Cape knifejaw, can reach a maximum length around 90 cm (35 in). Knifejaws have teeth fused into a parrot-like beak in adulthood. They feed on barnacles and mollusks, and are fished commercially. They are native to the Indian and Pacific Oceans. The earliest records of knifejaws are fossilized beaks, with attached teeth, known from middle Eocene-aged sediments of the La Meseta Formation of Antarctica. Their early occurrence in Antarctica supports it having temperate climate during the Eocene, and that knifejaws had a wider distribution in the past than today. Species The currently recognized species in this genus are: * '' Oplegnathus conwayi'' J. Richardson, 1840, 1840 (Cape knifejaw) * '' Oplegnathus fasciatus'' ( Temminck & Schlegel, 1844) ( barred knifejaw or striped beakfish) * '' Oplegnathus insignis'' ...

He was famous for the ''Atlas Ichthyologique des Indes Orientales Néêrlandaises'', his monumental work on the fishes of East Asia published between 1862 and 1877. Life and work Bleeker was born on 10 July 1819 in Zaandam. He was employed as a medical officer in the Royal Netherlands East Indies Army from 1842 to 1860, (in French). stationed in the Dutch East Indies (now Indonesia). During that time, he did most of his ichthyology work, besides his duties in the army. He acquired many of his specimens from local fishermen, but he also built up an extended network of contacts who would send him specimens from various government outposts throughout the islands. During his time in Indonesia, he collected well over 12,000 specimens, many of which currently reside at the Naturalis Biodiversity Center in Leiden. Bleeker corresponded with Auguste Dum� ...

Hermann Schlegel
Hermann Schlegel (10 June 1804 – 17 January 1884) was a German ornithologist, herpetologist and ichthyologist. Early life and education Schlegel was born at Altenburg, the son of a brassfounder. His father collected butterflies, which stimulated Schlegel's interest in natural history. The discovery, by chance, of a buzzard's nest led him to the study of birds, and a meeting with Christian Ludwig Brehm. Schlegel started to work for his father, but soon tired of it. He travelled to Vienna in 1824, where, at the university, he attended the lectures of Leopold Fitzinger and Johann Jacob Heckel. A letter of introduction from Brehm to Joseph Natterer gained him a position at the Naturhistorisches Museum. Ornithological career One year after his arrival, the director of this natural history museum, Carl Franz Anton Ritter von Schreibers, recommended him to Coenraad Jacob Temminck, director of the Rijksmuseum van Natuurlijke Historie, natural history museum of Leiden, who was seeking an ...

Barred Knifejaw
The barred knifejaw (''Oplegnathus fasciatus''), also known as the striped beakfish or rock bream, is a species of marine ray-finned fish, from the Family (biology), family Oplegnathidae. It is commonly native to the north-western Pacific Ocean, though a smattering of records exist from other localities in the eastern Pacific such as Hawaii and Chile. Recently introduced – likely via ballast water – in the central Mediterranean, it is found very rarely from Malta to the northern Adriatic. There is no listed conservation status for this species, though it is farmed for consumption and angling in many Asian countries suggesting it is common. The barred knifejaw is an inhabitant of rocky reefs and occurs at depths from 1 to 10 m (3 to 33 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). As with all members of the Oplegnat ...
