Snipefish
''Macroramphosus'', snipefishes or bellowfishes, is a genus of fishes found in tropical and subtropical oceans at depths down to . According to FishBase, they are part of the family Centriscidae, but Nelson (2016) split that family, in which case the genus ''Macroramphosus'' is in the family Macroramphosidae. They have long second spines on their dorsal fins and tiny mouths at the tip of their greatly elongated snouts. The bodies of snipefish are more streamlined than in the related bellowfishes. They reach a maximum length of about , and are silvery or reddish in colour. They are sometimes found in large schools. This is the only genus on the monogeneric family Macroranphosidae but some authorities include the genera '' Centriscops'' and '' Notopogon'' in this family too. Species Currently, two recognized species are placed in this genus: * '' Macroramphosus gracilis'' ( R. T. Lowe, 1839) (slender snipefish) * '' Macroramphosus scolopax'' (Linnaeus Carl Linnaeus (23 Ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Notopogon
The bellowfishes or bellowsfishes are fishes in the genus ''Notopogon'' in the family Centriscidae. They are found in deeper parts of the temperate southern oceans, although the longspine bellowfish has been recorded as far north as New Caledonia and Madagascar. According to FishBase, they are part of the family Centriscidae, but some authorities split that family, in which case the genus ''Notopogon'' is in the family Macroramphosidae, which is followed here. They have long second spines on their dorsal fins and tiny mouths at the tip of their greatly elongated snouts. Their bodies are relatively high (giving them a somewhat hunchbacked appearance), unlike the related snipefishes. They reach a maximum length of about , and are silvery or reddish in colour. Species The currently recognized species in this genus are: * '' Notopogon armatus'' ( Sauvage, 1879) * '' Notopogon fernandezianus'' ( Delfín, 1899) (orange bellowsfish) * '' Notopogon lilliei'' Regan, 1914 (crested bello ...

Centriscidae
The Centriscidae are a family of fishes from the order Syngnathiformes which includes the snipefishes, shrimpfishes, and bellowfishes. A small family, consisting of only about a dozen marine species, they are of an unusual appearance, as reflected by their common names. The species in this family are restricted to relatively shallow, tropical parts of the Indo-Pacific. Description They have extremely compressed, razor-like bodies which have a sharp ventral edge and a dorsal surface which is nearly straight in profile ending in a long snout which has a tiny mouth with pincer-like jaws which lack teeth. The spiny part of the dorsal fin is located close to the tail and is made of one long, sharp spine at the anterior end with two shorter spines behind that. The soft, posterior part of the dorsal fin and the caudal fin are situated on the ventral surface and lie below the posterior-most part of the body, which is pointed. The pelvic fins are small and are located around the middle o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Monogeneric
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 system. ...

Carl Linnaeus
Carl Linnaeus (23 May 1707 – 10 January 1778), also known after ennoblement in 1761 as Carl von Linné,#Blunt, Blunt (2004), p. 171. was a Swedish biologist and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern Taxonomy (biology), taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was the son of a curate and was born in Råshult, in the countryside of Småland, southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richard Thomas Lowe
Richard Thomas Lowe (1802–1874) was an English botanist, ichthyologist, malacologist, and clergyman. In 1825 he graduated from Christ's College, Cambridge, and in the same year he took holy orders. In 1832 he became a clergyman in the Madeira Islands, where he was also a part-time naturalist, extensively studying the local flora and fauna. He wrote a book on the Madeiran flora. He died in 1874 when the ship he was on was wrecked off the Isles of Scilly. Taxa Lowe named and described numerous molluscan taxa, including: * '' Caseolus'', a land snail genus and eight species within it * '' Lemniscia'', a land snail A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial molluscs, terrestrial gastropod mollusks that have gastropod shell, shel ... genus and two species within it See also * :Taxa named by Richard Thomas Lowe References * Notes 1802 birt ...

Dorsal Fin
A dorsal fin is a fin on the back of most marine and freshwater vertebrates. Dorsal fins have evolved independently several times through convergent evolution adapting to marine environments, so the fins are not all homologous. They are found in most fish, in mammals such as whales, and in extinct ancient marine reptiles such as ichthyosaurs. Most have only one dorsal fin, but some have two or three. Wildlife biologists often use the distinctive nicks and wear patterns which develop on the dorsal fins of whales to identify individuals in the field. The bones or cartilages that support the dorsal fin in fish are called pterygiophores. Functions The main purpose of the dorsal fin is usually to stabilize the animal against rolling and to assist in sudden turns. Some species have further adapted their dorsal fins to other uses. The sunfish uses the dorsal fin (and the anal fin Fins are moving appendages protruding from the body of fish that interact with water to ge ...

School (fish)
In biology, any group of fish that stay together for social reasons are shoaling, and if the group is swimming in the same direction in a coordinated manner, they are schooling. In common usage, the terms are sometimes used rather loosely. About one quarter of fish species shoal all their lives, and about one half shoal for part of their lives. Fish derive many benefits from shoaling behaviour including defence against predators (through better predator detection and by diluting the chance of individual capture), enhanced foraging success, and higher success in finding a mate. It is also likely that fish benefit from shoal membership through increased hydrodynamic efficiency. Fish use many traits to choose shoalmates. Generally they prefer larger shoals, shoalmates of their own species, shoalmates similar in size and appearance to themselves, healthy fish, and kin (when recognized). The oddity effect posits that any shoal member that stands out in appearance will be preferen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
