Léon Vaillant
Léon Louis Vaillant (; 11 November 1834 – 24 November 1914) was a French zoologist. He is most famous for his work in the areas of herpetology, malacology, and ichthyology. In 1854 he graduated from the College d'Arras, followed by studies in medicine and zoology in Paris. In 1861, he received his medical doctorate, then continued his zoological studies with Henri Milne-Edwards (1800-1885), earning his degree in natural sciences in 1865. In 1875, he became a professor at the Museum of Natural History in Paris. He held a special interest involving the systematics and anatomy of turtles and crocodiles, but also made significant contributions in his investigations of reptilian physiology and behavior. Of his 200-plus scientific writings, 90 of them are based on herpetological subjects. He participated in French naval expeditions on the ''Travailleur'' in 1880, 1881 and 1882 and on the ''Talisman'' in 1883. Eponyms The following are several species of marine organisms named ...

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 ...

Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Zoarcidae
The eelpouts are the ray-finned fish family (biology), family Zoarcidae. As the common name suggests, they are somewhat eel-like in appearance. All of the roughly 300 species are ocean, marine and mostly bottom-dwelling, some at great depths. Eelpouts are predominantly found in the Northern Hemisphere. The arctic, north pacific and north Atlantic oceans have the highest concentration of species, however species are found around the globe. They are conventionally placed in the "perciform" assemblage; in fact, the Zoarcoidei seem to be specialized members of the Gasterosteiformes-Scorpaeniformes group of Acanthopterygii. The largest member of the family is ''Zoarces americanus'', which may reach 1.1 m in length. Other notable genera include ''Lycodapus'' and ''Gymnelus''. Taxonomy The eelpout family was first proposed as the family Zoarchidae in 1839 by the English naturalist William John Swainson but the spelling was changed to Zoarcidae after the spelling of the genus Zoarces w ...

Benthic
The benthic zone is the ecological region at the lowest level of a body of water such as an ocean, lake, or stream, including the sediment surface and some sub-surface layers. The name comes from ancient Greek, βένθος (bénthos), meaning "the depths." Organisms living in this zone are called benthos and include microorganisms (e.g., bacteria and fungi) as well as larger invertebrates, such as crustaceans and polychaetes. Organisms here generally live in close relationship with the substrate and many are permanently attached to the bottom. The benthic boundary layer, which includes the bottom layer of water and the uppermost layer of sediment directly influenced by the overlying water, is an integral part of the benthic zone, as it greatly influences the biological activity that takes place there. Examples of contact soil layers include sand bottoms, rocky outcrops, coral, and bay mud. Description Oceans The benthic region of the ocean begins at the shore line (intertidal ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Rockall
Rockall () is an uninhabitable granite islet situated in the North Atlantic Ocean. The United Kingdom claims that Rockall lies within its exclusive economic zone (EEZ) and is part of its territory, but this claim is not recognised by Ireland. It and the nearby skerries of Hasselwood Rock and Helen's Reef are the only emergent parts of the Rockall Plateau. The rock was formed by magmatism as part of the North Atlantic Igneous Province during the Paleogene. Rockall's approximate distances from the closest islands in each direction are as follows: It is west of Soay, Scotland; northwest of Tory Island, Ireland; and south of Iceland. The nearest permanently inhabited place is North Uist, an island in the Outer Hebrides of Scotland, to the east. The United Kingdom claimed Rockall in 1955 and incorporated it as a part of Scotland in 1972. The UK does not make a claim to extended EEZ based on Rockall, as it has ratified the United Nations Convention on the Law of the Sea (UNCLOS ...

Lycenchelys
''Lycenchelys'' is a genus of marine ray-finned fishes belonging to the family Zoarcidae, the eelpouts. The genus has almost cosmopolitan distribution. Taxonomy ''Lycenelchys'' was first proposed as a genus in 1884 by the American ichthyologist Theodore Gill with ''Lycodes muraena'' being designated as the type species in 1920 by David Starr Jordan, this species was originally described by the Norwegian zoologist Robert Collett in 1878 with its type locality given as west-southwest of Bodø in Norway, at a depth of . The genus is classified in the subfamily Lycodinae, one of four subfamilies in the family Zoarcidae, the eelpouts. Species ''Lycenchelys'' contains the following species: Etymology ''Lycenchelys'' is a combination of ''lyc'', a referencce to the genus ''Lycodes'' and '' enchelys'', the Greek word for "eel". i.e. similar to ''Lycodes'' but with a more elongated eel-like shape. Characteristics ''Lycenelchys'' are regarded as derived Lycodine eelpouts which are s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish Described In 1888
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. Most fis ...
