Lutjaninae
Lutjaninae is a subfamily of marine ray-finned fishes, one of four subfamilies classified within the Family (biology), family Lutjanidae, the snappers. Genera The subfamily Lutjaninae contains 6 genera and 76 species: * genus ''Hoplopagrus'' Gill, 1861 * genus ''Lutjanus'' Marcus Elieser Bloch, Bloch, 1790 * genus ''Macolor'' Pieter Bleeker, Bleeker, 1860 * genus ''Ocyurus'' Gill, 1862 * genus ''Pinjalo (genus), Pinjalo'' Bleeker, 1873 * genus ''Rhomboplites'' Gill, 1862 A taxonomic study of snappers within the subfamily Lutjaninae in the tropical western Atlantic Ocean indicated that the monotypic genera ''Ocyurus'' and ''Rhomboplites'' sit within the genus ''Lutjanus''. Fossil history The Lutjaninae are represented in the fossil record as far back as the 48.6 million years ago from the Eocene where specimens have been found in the United Kingdom and Louisiana. More recent specimens are known from the Miocene in Mexico and Florida and the Quaternary of the Turks and Caicos Is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutjanus
''Lutjanus'' is a genus of marine ray-finned fish, snappers belonging to the Family (biology), family Lutjanidae. They are found in the Atlantic Ocean, Atlantic, Indian Ocean, Indian, and Pacific Oceans. They are predation, predatory fish usually found in tropical and subtropical reefs, and mangrove forests. This genus also includes two species that only occur in fresh water, fresh and brackish waters. Taxonomy ''Lutjanus'' was created in 1790 by the German people, German physician and zoologist Marcus Elieser Bloch with ''Lutjanus lutjanus'' as its type species by tautonymy. It is the type genus of the subfamily Lutjaninae and the family Lutjanidae. The name is derived from a local Indonesian name for snappers, ''ikhan Lutjang''. Bloch erroneously stated that the Type locality (biology), type locality for ''L. lutjanus'' was Japan when the name he gave it suggested that it was collected in the East Indies. A taxonomic study of snappers within the subfamily Lutjaninae in the tro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pinjalo (genus)
''Pinjalo'' is a genus of marine ray-finned fish, snappers belonging to the family Lutjanidae. They are native to the Indian Ocean and the western Pacific Ocean Taxonomy ''Pinjalo'' was created as a monotypic genus by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker, it was a monotypic genus containing only Bleeker's ''Caesio pinjalo'', which he had Species description described in 1850. A second species, ''P. lewisi'' was added in 1987. The generic name ''Pinjalo'' is derived from a Malay word for a fish ''pinialo''. The genus is classified within the subfamily Lutjaninae. Species The following two species are classified within the genus ''Pinjalo'': * '' Pinjalo lewisi'' J. E. Randall, G. R. Allen & W. D. Anderson, 1987 (slender pinjalo) * '' Pinjalo pinjalo'' ( Bleeker, 1850) (pinjalo) Characteristics ''Pinjalo'' snappers are medium-sized snappers and have moderately deep bodies with a comparatively small heads and a pointed snout. The eyes are place ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutjanidae
Lutjanidae or snappers are a family of perciform fishes, mainly marine but with some members inhabiting estuaries and, in some cases, fresh water (e.g., '' Lutjanus goldiei''). The family includes about 113 species. Most species are used for food and many are of high economic importance. Many species around the world are known in local languages as red snapper, including species from different genera (including Lutjanus and Pristipomoides) Snappers inhabit tropical, subtropical, and warm-temperate regions of all oceans. Some snappers grow up to about in length, and one species, the cubera snapper, grows up to in length. Most are active carnivores, feeding on crustaceans or other fishes, though a few are plankton-feeders. They can be kept in aquaria, but commonly grow too fast to be popular aquarium fish. Most species live at depths reaching near coral reefs, but some species are found up to deep. As with other fishes, some snapper species host parasites. A detailed st ...

Macolor
''Macolor'' is a genus of marine ray-finned fish, snappers belonging to the family Lutjanidae. They are native to the Indian Ocean and the western Pacific Ocean. Taxonomy ''Macolor'' was described as a genus in 1860 by the Dutch physician, herpetologist and ichthyologist Pieter Bleeker. Bleeker used the name ''Macolor'' tautonymously as the type species was Cuvier’s ''Diacope macolor'' which Bleeker renamed, needlessly, ''Macolor typus''. The name may be derived from ''macula'', Latin for “spot” a reference to the white spotting on the otherwise black body of the juveniles of ''M. niger''. The genus is placed within the subfamily Lutjaninae. Species The currently recognized species in this genus are: * '' Macolor macularis'' Fowler, 1931 (midnight snapper) * '' Macolor niger'' ( Forsskål, 1775) (black and white snapper) Characteristics ''Macolor'' snappers are medium-sized with a relatively deep, oblong body. They have quite a large mouth which can be ptrotracted. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lutjanus Lutjanus
The bigeye snapper (''Lutjanus lutjanus''), also known as the bigeye seaperch, red sea lined snapper, golden striped snapper, rosy snapper, yellow snapper, or simply snapper, is a species of marine ray-finned fish, a snapper belonging to the Family (biology), family Lutjanidae. It is native to the Indian Ocean and the western Pacific Ocean. It is the type species of the genus ''Lutjanus''. Taxonomy The bigeye snapper was first formally Species description, described in 1790 by the German people, German physician and zoologist Marcus Elieser Bloch with the Type locality (biology), type locality given as Japan, although this is thought to be erroneous and is actually Indonesia. Bloch named the genus ''Lutjanus'' when he described this species and it is the type species of that genus by tautonymy. The name, ''lutjanus'', is derived from a local Indonesian name for snappers, ''ikhan Lutjang''. Description The bigeye snapper has a fusiform, slender body which has a standard length t ...

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS), as well as the current and most recent of the twelve periods of the Phanerozoic eon. It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today); a proposed third epoch, the Anthropocene, was rejected in 2024 by IUGS, the governing body of the ICS. The Quaternary is typically defined by the Quaternary glaciation, the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four succ ...

Miocene
The Miocene ( ) is the first epoch (geology), geological epoch of the Neogene Period and extends from about (Ma). The Miocene was named by Scottish geologist Charles Lyell; the name comes from the Greek words (', "less") and (', "new") and means "less recent" because it has 18% fewer modern marine invertebrates than the Pliocene has. The Miocene followed the Oligocene and preceded the Pliocene. As Earth went from the Oligocene through the Miocene and into the Pliocene, the climate slowly cooled towards a series of ice ages. The Miocene boundaries are not marked by distinct global events but by regionally defined transitions from the warmer Oligocene to the cooler Pliocene Epoch. During the Early Miocene, Afro-Arabia collided with Eurasia, severing the connection between the Mediterranean and Indian Oceans, and allowing the interchange of fauna between Eurasia and Africa, including the dispersal of proboscideans and Ape, hominoids into Eurasia. During the late Miocene, the conn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Louisiana
Louisiana ( ; ; ) is a state in the Deep South and South Central regions of the United States. It borders Texas to the west, Arkansas to the north, and Mississippi to the east. Of the 50 U.S. states, it ranks 31st in area and 25th in population, with roughly 4.6 million residents. Reflecting its French heritage, Louisiana is the only U.S. state with political subdivisions termed parishes, which are equivalent to counties, making it one of only two U.S. states not subdivided into counties (the other being Alaska and its boroughs). Baton Rouge is the state's capital, and New Orleans, a French Louisiana region, is its most populous city with a population of about 363,000 people. Louisiana has a coastline with the Gulf of Mexico to the south; a large part of its eastern boundary is demarcated by the Mississippi River. Much of Louisiana's lands were formed from sediment washed down the Mississippi River, leaving enormous deltas and vast areas of coastal marsh a ...

Eocene
The Eocene ( ) is a geological epoch (geology), epoch that lasted from about 56 to 33.9 million years ago (Ma). 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'', 'Eos, Dawn') and (''kainós'', "new") and refers to the "dawn" of modern ('new') fauna that appeared during the epoch.See: *Letter from William Whewell to Charles Lyell dated 31 January 1831 in: * From p. 55: "The period next antecedent we shall call Eocene, from ήως, aurora, and χαινος, recens, because the extremely small proportion of living species contained in these strata, indicates what may be considered the first commencement, or ''dawn'', of the existing state of the animate creation." 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 isoto ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic
In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unispecific" or "monospecific" is sometimes preferred. In botanical nomenclature, a monotypic genus is a genus in the special case where a genus and a single species are simultaneously described. Theoretical implications Monotypic taxa present several important theoretical challenges in biological classification. One key issue is known as "Gregg's Paradox": if a single species is the only member of multiple hierarchical levels (for example, being the only species in its genus, which is the only genus in its family), then each level needs a distinct definition to maintain logical structure. Otherwise, the different taxonomic ranks become effectively identical, which creates problems for organizing biological diversity in a hierarchical syste ...
