Armored Gurnard
Peristediidae, the armored sea robins or armoured gurnards, is a family of ray-finned fishes belonging to the suborder Platycephaloidei in the order Scorpaeniformes. They are found in the deep water in the tropical and warm temperate of the world's oceans. Taxonomy Peristediidae was first proposed as a family in 1883 by the American ichthyologists David Starr Jordan and Charles Henry Gilbert. The 5th edition of ''Fishes of the World'' classifies the family within the Platycephaloidei, which is a suborder of the order Scorpaeniformes. Other authorities differ and do not consider the Scorpaeniformes to be a valid order because the Perciformes is not monophyletic without the taxa within the Scorpaeniformes being included within it. These authorities consider the Peristediidae to belong to the suborder Triglioidei, along with the family Triglidae, within the Perciformes. The family Peristediidae is included in the Triglidae as the subfamily Peristediinae by some authorities. Gene ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heminodus
''Heminodus'' is a genus of marine ray-finned fish belonging to the family Peristediidae, the armoured gurnards or armored sea robins. It is currently considered to be a monotypic genus, its only species being ''Heminodus philippinus''. Taxonomy ''Heminodus'' was first described as a genus in 1917 by the American ichthyologist Hugh McCormick Smith when he was describing its only species ''H. phillipinus'' with its type locality being given as the Mindanao Sea off Tawi-tawi in the Philippines. Specimens collected in the eastern Indian Ocean off Western Australia between 1989 and 1991 were identified as probably belonging to the genus Hemidonus but were not identified to species, so may have been ''H. phillipinus'' or a new undescribed species. The genus name was not explained by Smith but means "half knot", may be an allusion to the short and spiny rostral processes as compared to the long and flat processes on the jaggedhead gurnard (''Gargariscus prionocephalus'').

Peristedion Paucibarbiger
''Peristedion'' is a genus of marine ray-finned fish belonging to the family (biology), family Peristediidae, the armoured gurnards or armored sea robins. These fishes are found in Atlantic Ocean, Atlantic and Indo-West Pacific ocean waters. Taxonomy Peristedion was first described as a genus in 1801 by the French naturalist Bernard Germain de Lacépède when he species description, described ''Peristedion marmalat'' from the Mediterranean Sea and the Moluccas. In 1826 Jean Baptiste Bory de Saint-Vincent designated ''P. marmalat'' as the type species of the genus. ''P. marmalat'' is now treated as a junior synonym of Carl Linnaeus's ''Trigla cataphracta'', which he described from the Mediterranean Sea off southern France. Within the family Peristediidae there are 2 clades, this genus is in a Monotypic taxon, monotypic clade while the other clade is made up of the remaining 5 genera of the Peristediidae. The name of the genus ''Peristedion'' is a combination of ''peri'', meaning ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anal Fin
Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as seen in sharks. Apart from the tail or caudal fin, fish fins have no direct connection with the spine and are supported only by muscles. Their principal function is to help the fish swim. Fins located in different places on the fish serve different purposes such as moving forward, turning, keeping an upright position or stopping. Most fish use fins when swimming, flying fish use pectoral fins for gliding, and frogfish use them for crawling. Fins can also be used for other purposes; male sharks and mosquitofish use a modified fin to deliver sperm, thresher sharks use their caudal fin to stun prey, reef stonefish have spines in their dorsal fins that inject venom, anglerfish use the first spine of their dorsal fin like a fishing rod to lu ...

Dorsal Fin
A dorsal fin is a fin located on the back of most marine and freshwater vertebrates within various taxa of the animal kingdom. Many species of animals possessing dorsal fins are not particularly closely related to each other, though through convergent evolution they have independently evolved external superficial fish-like body plans adapted to their marine environments, including most numerously fish, but also mammals such as cetaceans (whales, dolphins, and porpoises), and even extinct ancient marine reptiles such as various known species of ichthyosaurs. Most species 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 large cetaceans to identify individuals in the field. The bony or cartilaginous bones that support the base of the dorsal fin in fish are called ''pterygiophores''. Functions The main purpose of the dorsal fin is to stabilize the animal against rollin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trigla
The piper gurnard (''Trigla lyra''), also known as the piper or the lyre gurnard, is a species of marine, demersal ray-finned fish from the family Triglidae, the gurnards and sea robins. It is found in the eastern Atlantic Ocean and the Mediterranean Sea. It is the only species in the monotypic genus ''Trigla''. Taxonomy The piper gurnard was first formally described in 1758 by Carl Linnaeus in the 10th edition of his Systema Naturae with its type locality given as "British Seas". It is the only species in the monotypic genus ''Trigla'' which is classified within the subfamily Triglinae, within the family Triglidae. In 1883 David Starr Jordan and Charles Henry Gilbert designated this species as the type species of the genus ''Lyra'', which was not thought to be monotypic at that time. The genus name, ''Trigla'', is a classical name for the red mullet (''Mullus barbatus''), Artedi thought the red mullet and the gurnards were the same as fishes from both taxa are known to create ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Scalicus
''Scalicus'' is a genus of marine ray-finned fish belonging to the family Peristediidae, the armoured gurnards or armored searobins. These fishes are found in the Indo-Pacific region. Taxonomy ''Scalicus'' was first described as a monotypic genus in 1923 by the American ichthyologist David Starr Jordan with the newly described ''Peristedion amiscus'', designated as its type species. Within the family Peristediidae there are 2 clades, this genus is in the clade consisting of 5 genera, with the nominate genus ''Peristedion'' in the other clade. Jordan did not explain the genus name's etymology but it may be from ''skallo'' meaning "hoe", an allusion top the shovel shaped snout of the type species. Species ''Scalicus'' currently has 8 recognised species within it: * '' Scalicus amiscus'' D. S. Jordan & Starks, 1904 * '' Scalicus engyceros'' Günther, 1872 * '' Scalicus gilberti'' D. S. Jordan, 1921 * '' Scalicus hians'' C. H. Gilbert & Cramer, 1897 * '' Scalicus investigator ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Jakob Kaup
Johann Jakob von Kaup (10 April 1803 – 4 July 1873) was a German naturalist. A proponent of natural philosophy, he believed in an innate mathematical order in nature and he attempted biological classifications based on the Quinarian system. Kaup is also known for having coined popular prehistoric taxa like '' Pterosauria'' and ''Machairodus''. Biography He was born at Darmstadt. After studying at Göttingen and Heidelberg he spent two years at Leiden, where his attention was specially devoted to the amphibians and fishes. He then returned to Darmstadt as an assistant in the grand ducal museum, of which in 1840 he became inspector. In 1829 he published ''Skizze zur Entwickelungsgeschichte der europäischen Thierwelt'', in which he regarded the animal world as developed from lower to higher forms, from the amphibians through the birds to the beasts of prey; but subsequently he repudiated this work as a youthful indiscretion, and on the publication of Darwin's ''Origin of Species' ...

Satyrichthys
''Satyrichthys'' is a genus of marine ray-finned fish belonging to the family Peristediidae, the armoured gurnards or armored searobins. These fishes are found in the Indo-Pacific region. Taxonomy ''Satyrichthys'' was first described as a monotypic genus in 1873 by the German zoologist Johann Jakob Kaup with ''Peristethus rieffeli'' as its only species. Kaup had described P. reifeli in 1853 with iots type locality given as China. Within the family Peristediidae there are 2 clades, this genus is in the clade consisting of 5 genera, with the nominate genus ''Peristedion'' in the other clade. The name of the genus ''Satyrichtys'' was not explained by Kaup but it combines ''satyr'', meaning "god" or "demon", with ''ichthys'', meaning "fish", the first part may be an allusion to the two fork-shaped projections at the end of the snout of ''S. rieffeli'', resembling the horns depicted on demons. Species ''Satyrichthys'' currently contains 7 recognized species: * '' Satyrichthys clav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bernard Germain De Lacépède
Bernard-Germain-Étienne de La Ville-sur-Illon, comte de Lacépède or La Cépède (; 26 December 17566 October 1825) was a French naturalist and an active freemason. He is known for his contribution to the Comte de Buffon's great work, the ''Histoire Naturelle''. Biography Lacépède was born at Agen in Guienne. His education was carefully conducted by his father, and the early perusal of Buffon's Natural History ('' Histoire naturelle, générale et particulière'') awakened his interest in that branch of study, which absorbed his chief attention. His leisure he devoted to music, in which, besides becoming a good performer on the piano and organ, he acquired considerable mastery of composition, two of his operas (which were never published) meeting with the high approval of Gluck; in 1781–1785 he also brought out in two volumes his ''Poétique de la musique''. Meantime he wrote two treatises, ''Essai sur l'électricité'' (1781) and ''Physique générale et particuliè ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
