Setarchidae
Setarchinae, the deep-sea bristly scorpionfishes, is a small subfamily of deep-sea ray-finned fishes, it is part of the family Scorpaenidae. They are small marine fishes, growing up to 25 cm, and are found in tropical and subtropical waters throughout the world. Taxonomy Setarchinae, or the family Setarchidae, were first described as a taxon by the Japanese ichthyologist Kiyomatsu Matsubara in 1943. The grouping is treated as a subfamily of the Scorpaenidae within the order Scorpaeniformes by the 5th Edition of ''Fishes of the World''. However, other authorities, such as FishBase, regard the taxon as a family within the suborder Scorpaenoidei, part of the Perciformes. The name of the subfamily comes from ''Setarches'' which was described by the English zoologist James Yate Johnson in 1862 but Johnson did not explain what the name alluded to, it may be derived from ''saeta'' meaning "bristle".

Lythrichthys
''Lythrichthys'', the red deepwater scorpionfishes, is a genus of marine ray-finned fish, belonging to the subfamily Setarchinae, the deep-sea bristly scorpionfishes, part of the family Scorpaenidae. They are native to the Pacific Ocean. Taxonomy ''Lythrichthys'' was first described as a genus in 1904 by the American ichthyologists David Starr Jordan and Edwin Chapin Starks as a monotypic genus for ''Lythrichthys eulabes'' which they described with a type locality given as off Ose Point in Suruga Bay in Japan. ''L. eulabes'' was later placed in the genus '' Setarches'' and ''Lythrichthys'' became a synonym of that taxon. However, in 2021 Wada, Kai & Motomura resurrected the genus, added ''L. cypho'' (which had been treated as a synonym of''Setarches longimanus''), as well as ''L. longimanus'', and described two new species. This left the channelled rockfish (''Setarches guentheri'') as the only species in the now monotypic ''Setarches'' As of January 2022 this change has bee ...

Lioscorpius
''Lioscorpius''is a genus of marine ray-finned fish, belonging to the subfamily Setarchinae, the deep-sea bristly scorpionfishes, part of the family Scorpaenidae. They are native to the western Pacific Ocean. Taxonomy ''Lioscorpius''as formally described as a genus in 1880 by the German-born British ichthyologist Albert Günther when he described what was then its only species, ''L. longiceps'', from the Kai Islands in the Banda Sea in Indonesia. The genus name ''Lioscorpius'' is a compound of ''lio'', meaning "smooth", Gunther described the head of ''L. longiceps'' "with scarcely any ridges or spines", and ''scorpius'' which means "scorpion", indicating that this is a scorpionfish. Species There are currently two recognized species in this genus: * '' Lioscorpius longiceps'' Günther, 1880 (Slender scorpionfish) * '' Lioscorpius trifasciatus'' Last, Yearsley & Motomura, 2005 (Tripleband scorpionfish) Characteristics ''Lioscorpius'' scorpionfishes have a preorbital bone wh ...

Ectreposebastes
''Ectreposebastes'' is a genus of marine ray-finned fish, belonging to the subfamily Setarchinae, the deep-sea bristly scorpionfishes, part of the family Scorpaenidae. The genus is found in the Atlantic, Indian and Pacific Oceans. Taxonomy ''Ectreposebastes'' was first described as a monotypic genus in 1899 by the American ichthyologist Samuel German when he described what was then its only species, ''E. imus'', from the Galápagos Islands. The genus name ''Ectreposebastes'' is a compound of ''ectrepos'' which means “reversed”, German did not explain this, and ''Sebastes''. It may refer to the greater depth of the body with the back arching higher under the soft-rayed part of the dorsal fin, whereas in '' S. diploproa'' the species Garman cited for comparison purposes, the greatest body depth occurs under spiny part of the dorsal fin. Species There are currently two recognized species in this genus: * '' Ectreposebastes imus'' Garman, 1899 (Midwater scorpionfish) * '' Ect ...

Perciformes
Perciformes (), also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". Perciformes is an Order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems. The order contains about 160 families, which is the most of any order within the vertebrates. It is also the most variably sized order of vertebrates, ranging from the ''Schindleria brevipinguis'' to the marlin in the genus ''Makaira''. They first appeared and diversified in the Late Cretaceous. Among the well-known members of this group are perch and darters (Percidae), sea bass and groupers (Serranidae). Characteristics The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or compl ...

Ray-finned Fish
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 Actinoptery ...

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...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] |
Ossification
Ossification (also called osteogenesis or bone mineralization) in bone remodeling is the process of laying down new bone material by cells named osteoblasts. It is synonymous with bone tissue formation. There are two processes resulting in the formation of normal, healthy bone tissue: Intramembranous ossification is the direct laying down of bone into the primitive connective tissue ( mesenchyme), while endochondral ossification involves cartilage as a precursor. In fracture healing, endochondral osteogenesis is the most commonly occurring process, for example in fractures of long bones treated by plaster of Paris, whereas fractures treated by open reduction and internal fixation with metal plates, screws, pins, rods and nails may heal by intramembranous osteogenesis. Heterotopic ossification is a process resulting in the formation of bone tissue that is often atypical, at an extraskeletal location. Calcification is often confused with ossification. Calcification is sy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
