Auchenionchus Variolosus
''Auchenionchus variolosus'' is a species of labrisomid blenny endemic to the Pacific waters off the coast of Chile. While juveniles primarily consume amphipods, their diet shifts to decapods as the mature. This species can reach in total length. Biology Study shows that the larvae of ''A. variolosus'' has a diet that is composed of mainly 15-19 prey items. These include early stages of copepods; the nauplii, metanauplii and copepodites, dinoflagellate cysts, cypris larvae, calyptopis, ostracods Ostracods, or ostracodes, are a class of the Crustacea (class Ostracoda), sometimes known as seed shrimp. Some 70,000 species (only 13,000 of which are extant) have been identified, grouped into several orders. They are small crustaceans, typical ..., the eggs of invertebrates and fishes. In terms of frequency, copepod nauplii are the most important prey item during the larval period. However, copepod nauplii are smaller in size and have low energy content therefore, with the ...

Labrisomid
Labrisomids are small blennioids (blennies), percomorph marine fish belonging to the family Labrisomidae. Found mostly in the tropical Atlantic and Pacific Ocean, the family contains about 110 species in 15 genera. Stockier than the average blenny, labrisomids are elongated nonetheless; their dorsal fin spines outnumber soft rays (which may be absent altogether), and their pelvic fins are long and slender. Like many other blennies, labrisomids have whisker-like structures called cirri on their heads and napes. Scales may be cycloid or absent in labrisomids; many species are brightly coloured. The hairy blenny (''Labrisomus nuchipinnis'') is the largest species at 23 cm in length; most are far smaller. Generally staying within shallow coastal regions to depths around 10 m, labrisomids are benthic fish spending most of their time on or near the bottom. Both sandy and rocky substrates are frequented, sometimes at reefs or amongst beds of seagrass. Labrisomids are shy fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Theodore Nicholas Gill
Theodore Nicholas Gill (March 21, 1837 – September 25, 1914) was an American ichthyologist, mammalogist, malacologist and librarian. Career Born and educated in New York City under private tutors, Gill early showed interest in natural history. He was associated with J. Carson Brevoort in the arrangement of the latter's entomological and ichthyological collections before going to Washington D.C. in 1863 to work at the Smithsonian Institution. He catalogued mammals, fishes and mollusks most particularly although maintaining proficiency in other orders of animals. He was librarian at the Smithsonian and also senior assistant to the Library of Congress. He was elected as a member of the American Philosophical Society in 1867. Gill was professor of zoology at George Washington University. He was also a member of the Megatherium Club at the Smithsonian Institution in Washington, D.C. Fellow members frequently mocked him for his vanity. He was president of the American Associat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pacific
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Chile
Chile, officially the Republic of Chile, is a country in the western part of South America. It is the southernmost country in the world, and the closest to Antarctica, occupying a long and narrow strip of land between the Andes to the east and the Pacific Ocean to the west. Chile covers an area of , with a population of 17.5 million as of 2017. It shares land borders with Peru to the north, Bolivia to the north-east, Argentina to the east, and the Drake Passage in the far south. Chile also controls the Pacific islands of Juan Fernández, Isla Salas y Gómez, Desventuradas, and Easter Island in Oceania. It also claims about of Antarctica under the Chilean Antarctic Territory. The country's capital and largest city is Santiago, and its national language is Spanish. Spain conquered and colonized the region in the mid-16th century, replacing Inca rule, but failing to conquer the independent Mapuche who inhabited what is now south-central Chile. In 1818, after declaring ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Leonard Blomefield
Leonard Jenyns (25 May 1800 – 1 September 1893) was an English clergyman, author and naturalist. He was forced to take on the name Leonard Blomefield to receive an inheritance. He is chiefly remembered for his detailed phenology observations of the times of year at which events in natural history occurred. Personal life Jenyns was born in 1800 at No. 85 Pall Mall, London, the home of his maternal grandfather. He was the youngest son of George Leonard Jenyns of Bottisham Hall, Cambridgeshire, a magistrate, landowner and a prebendary of Ely Cathedral. His mother Mary (1763–1832) was the daughter of Dr. William Heberden (1710–1801). His father had inherited the Bottisham Hall property on the death of his distant cousin Soame Jenyns (1704–1787). By 1812, Jenyns began to study natural history encouraged by his great uncle. He went to Eton in 1813 where he read, and was inspired by Gilbert White's ''Natural History of Selborne''. In 1817 Jenyns was introduced to Sir Jo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 17696 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and scie ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of living and fossil organisms as well as viruses. In the hierarchy of biological classification, genus comes above species and below family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. '' Panthera leo'' (lion) and '' Panthera onca'' (jaguar) are two species within the genus '' Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. phylogenetic analysis should cl ...
