Monacanthus Chinensis
''Monacanthus chinensis'', commonly known as the fan-bellied leatherjacket or fantail leatherjacket, is a species of filefish native to the western Pacific Ocean and the eastern Indian Ocean where it is found on reefs and soft sediments at shallow depths. This species grows to a total length of . Description The fan-bellied leatherjacket grows to a total length of about . It is a laterally-compressed fish recognisable by the upturned, pointed snout, the filamentary extension on the fan-shaped caudal fin, and the large dewlap on the underside of the fish. The foremost dorsal fin consists of a long erectile spine with a shorter one behind it. The hindermost dorsal fin has 28 to 34 soft rays and the anal fin has 27 to 34 soft rays. The colour is variable depending on its environment, being dark when swimming over beds of mussels and cream or tan when above a sandy seabed. In each case there are irregular darker blotches and streaks. Distribution and habitat The fan-bellied leather ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monacanthus Ciliatus
''Monacanthus ciliatus'', commonly known as the fringed filefish, the cuckold or the leather-fish, is a species of bony fish commonly found in shallow water in the western Atlantic Ocean, the Caribbean Sea and the Gulf of Mexico. Description The fringed filefish is a laterally flattened fish with a deeply keeled body and a dewlap on the underside. It typically grows to a length of , with a maximum length of . The eyes are large, the snout is short and pointed, and the mouth is small, with strong teeth. The dorsal fin is in two parts; the front section is just behind the eyes and consists of two spines, the first one being long and erectile and the second one being tiny; the second part starts further back and consists entirely of soft rays. The pectoral fins are small and the pelvic fin resembles a spine. The caudal fin is short and fan-shaped and consists of branched soft rays. The skin is clad in very small scales, which gives the fish a leathery appearance. The skin is also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filefish
The filefish (Monacanthidae) are a diverse family of tropical to subtropical tetraodontiform marine fish, which are also known as foolfish, leatherjackets or shingles. They live in the Atlantic, Pacific and Indian Oceans. Filefish are closely related to the triggerfish, pufferfish and trunkfish. The filefish family comprises approximately 102 species in 27 genera. More than half of the species are found in Australian waters, with 58 species in 23 genera. Their laterally compressed bodies and rough, sandpapery skin inspired the filefish's common name; it is said that dried filefish skin was once used to finish wooden boats. Description Appearing very much like their close relatives the triggerfish, filefish are rhomboid-shaped fish that have beautifully elaborate cryptic patterns. Deeply keeled bodies give a false impression of size when these fish are viewed facing the flanks. Filefish have soft, simple fins with comparatively small pectoral fins and truncated, fan-shaped tail ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tetraodontiformes
The Tetraodontiformes are an order of highly derived ray-finned fish, also called the Plectognathi. Sometimes these are classified as a suborder of the order Perciformes. The Tetraodontiformes are represented by 10 extant families and at least 349 species overall; most are marine and dwell in and around tropical coral reefs, but a few species are found in freshwater streams and estuaries. They have no close relatives, and descend from a line of coral-dwelling species that emerged around 80 million years ago. Description Various bizarre forms are included here, all radical departures from the streamlined body plan typical of most fishes. These forms range from nearly square or triangular (boxfishes), globose ( pufferfishes) to laterally compressed ( filefishes and triggerfishes). They range in size from '' Rudarius excelsus'' (a filefish), measuring just in length, to the ocean sunfish, the largest of all bony fishes at up to in length and weighing over 2 tonnes. Most members ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Chordata
A chordate () is an animal of the phylum Chordata (). All chordates possess, at some point during their larval or adult stages, five synapomorphies, or primary physical characteristics, that distinguish them from all the other taxa. These five synapomorphies include a notochord, dorsal hollow nerve cord, endostyle or thyroid, pharyngeal slits, and a post-anal tail. The name “chordate” comes from the first of these synapomorphies, the notochord, which plays a significant role in chordate structure and movement. Chordates are also Bilateral symmetry, bilaterally symmetric, have a coelom, possess a circulatory system, and exhibit Metameric, metameric segmentation. In addition to the morphological characteristics used to define chordates, analysis of genome sequences has identified two conserved signature indels (CSIs) in their proteins: cyclophilin-like protein and mitochondrial inner membrane protease ATP23, which are exclusively shared by all vertebrates, tunicates and cep ...

Actinopterygii
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 Actinopt ...

Lorenz Oken
Lorenz Oken (1 August 1779 – 11 August 1851) was a German naturalist, botanist, biologist, and ornithologist. Oken was born Lorenz Okenfuss (german: Okenfuß) in Bohlsbach (now part of Offenburg), Ortenau, Baden, and studied natural history and medicine at the universities of Freiburg and Würzburg. He went on to the University of Göttingen, where he became a ''Privatdozent'' (unsalaried lecturer), and shortened his name to Oken. As Lorenz Oken, he published a small work entitled ''Grundriss der Naturphilosophie, der Theorie der Sinne, mit der darauf gegründeten Classification der Thiere'' (1802). This was the first of a series of works which established him as a leader of the movement of " Naturphilosophie" in Germany. In it he extended to physical science the philosophical principles which Immanuel Kant (1724–1804) had applied to epistemology and morality. Oken had been preceded in this by Johann Gottlieb Fichte (1762–1814), who, acknowledging that Kant had discovered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), 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 taxonomy (biology), 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 ...

Pehr Osbeck
Pehr Osbeck (1723 – 23 December 1805) was a Swedish explorer, naturalist and an apostle of Carl Linnaeus. He was born in the parish of Hålanda on Västergötland and studied at Uppsala with Carolus Linnaeus. Naturalist in Canton In 1750–1752 he travelled as chaplain on the ship ''Prins Carl'' to Asia where he spent four months studying the flora, fauna, and people of the Canton region of China. He returned home just in time to contribute more than 600 species of plant to Linnaeus' ''Species Plantarum'', published in 1753. In 1757 he published the journal of his voyage to China, ''Dagbok öfwer en ostindisk Resa åren 1750, 1751, 1752'', which was translated into German in 1762 and English in 1771. In 1758, he was elected a member of the Royal Swedish Academy of Sciences. Later career He ended his career as the parish priest of Våxtorp and Hasslöv in Halland, where he died in 1805.
