Knifejaw
''Oplegnathus'' is currently the sole recognized genus in the knifejaw family (Oplegnathidae) of marine perciform 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. Species The currently recognized species in this genus are: * ''Oplegnathus conwayi'' J. Richardson, 1840, 1840 (Cape knifejaw) * ''Oplegnathus fasciatus'' (Temminck & Schlegel, 1844) (striped beakfish or barred knifejaw) * ''Oplegnathus insignis'' ( Kner, 1867) (Pacific beakfish) * ''Oplegnathus peaolopesi'' J. L. B. Smith, 1947 (Mozambique knifejaw) * ''Oplegnathus punctatus'' (Temminck & Schlegel, 1844) (spotted knifejaw) * ''Oplegnathus robinsoni'' Regan, 1916 (Natal knifejaw) * ''Oplegnathus woodwardi'' Waite, 1900 (knifejaw) Timeline ImageSize = width:1000px height:auto barincr ...

Striped Beakfish
The striped beakfish (''Oplegnathus fasciatus'') is a marine ray-finned fish, a knifejaw from the family Oplegnathidae. It is native to the northwestern Pacific Ocean, though a smattering of records exist from other localities in the eastern Pacific such as Hawaii and Chile. Recently introduced – probably via ballast water – in the central Mediterranean, it is found very rarely from Malta to the northern Adriatic. It is an inhabitant of rocky reefs and occurs at depths from . Juvenile members of this species can be found with patches of drifting seaweed. This species can reach a total length of , with the greatest recorded weight for this species of . The color pattern consists of light and dark vertical bars from which it derives its name. The species feeds mainly 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. Five striped beakfish, of which one remains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Oligocene
The Oligocene ( ) is a geologic epoch of the Paleogene Period and extends from about 33.9 million to 23 million years before the present ( to ). As with other older geologic periods, the rock beds that define the epoch are well identified but the exact dates of the start and end of the epoch are slightly uncertain. The name Oligocene was coined in 1854 by the German paleontologist Heinrich Ernst Beyrich from his studies of marine beds in Belgium and Germany. The name comes from the Ancient Greek (''olígos'', "few") and (''kainós'', "new"), and refers to the sparsity of extant forms of molluscs. The Oligocene is preceded by the Eocene Epoch and is followed by the Miocene Epoch. The Oligocene is the third and final epoch of the Paleogene Period. The Oligocene is often considered an important time of transition, a link between the archaic world of the tropical Eocene and the more modern ecosystems of the Miocene. Major changes during the Oligocene included a global expansion o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eocene
The Eocene ( ) Epoch is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (mya). It is the second epoch of the Paleogene Period (geology), Period in the modern Cenozoic Era (geology), Era. The name ''Eocene'' comes from the Ancient Greek (''ēṓs'', "dawn") and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch. The Eocene spans the time from the end of the Paleocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by a brief period in which the concentration of the carbon isotope Carbon-13, 13C in the atmosphere was exceptionally low in comparison with the more common isotope Carbon-12, 12C. The end is set at a major extinction event called the ''Grande Coupure'' (the "Great Break" in continuity) or the Eocene–Oligocene extinction event, which may be related to the impact of one or more large bolides in Popigai impact structure, Siberia and in what is now ...
