Achille Valenciennes
Achille Valenciennes (9 August 1794 – 13 April 1865) was a French zoologist. Valenciennes was born in Paris, and studied under Georges Cuvier. His study of parasitic worms in humans made an important contribution to the study of parasitology. He also carried out diverse systematic classifications, linking fossil and current species. He worked with Cuvier on the 22-volume "'' Histoire Naturelle des Poissons''" (Natural History of Fish) (1828–1848), carrying on alone after Cuvier died in 1832. In 1832, he succeeded Henri Marie Ducrotay de Blainville (1777–1850) as chair of ''Histoire naturelle des mollusques, des vers et des zoophytes'' at the Muséum national d'histoire naturelle. Early in his career, he was given the task of classifying animals described by Alexander von Humboldt (1769–1859) during his travels in the American tropics (1799 to 1803), and a lasting friendship was established between the two men. He is the binomial authority for many species of fish, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinoptery ...

Salmostoma
The razorbelly minnows are a group of fish in the genus ''Salmostoma'' found in southern Asia. They have been placed in the genus ''Salmophasia'' but this is regarded as a junior synonym of ''Salmostoma''. Species There are currently 13 recognized species in this genus: * '' Salmostoma acinaces'' (Valenciennes, 1844) (silver razorbelly minnow) * '' Salmostoma bacaila'' ( F. Hamilton, 1822) (large razorbelly minnow) * '' Salmostoma balookee'' (Sykes, 1839) (Bloch razorbelly minnow) * '' Salmostoma belachi'' (Jayaraj, Krishna Rao, Ravichandra Reddy, Shakuntala & Devaraj, 1999) * '' Salmostoma boopis'' ( F. Day, 1874) (Boopis razorbelly minnow) * '' Salmostoma horai'' (Silas, 1951) (Hora razorbelly minnow) * '' Salmostoma novacula'' (Valenciennes, 1840) (Novacula razorbelly minnow) * ''Salmostoma orissaensis'' ( Bănărescu, 1968) (Orissa razorbelly minnow) * '' Salmostoma phulo'' ( F.

Fish Described In 1840
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...
