Cristacirrhitus
The blackspotted hawkfish (''Cristacirrhitus punctatus'') is a species of marine ray-finned fish, a hawkfish belonging to the family Cirrhitidae. It is native to rocky shores of the western Indian Ocean. This species grows to in total length. This species is the only known member of its genus. Taxonomy The blackspotted hawkfish was first formally described in 1829 as ''Cirrhitus punctatus'' by the French zoologist Georges Cuvier with the type locality given as Madagascar. In 2001 John Ernest Randall placed it in a new monotypic genus, ''Cristacirrhitus''. The genus name is a compound of ''crista'' meaning "crest", a reference to the ridge of bone over the eye and ''Cirrhitus'' the type genus of the family Cirrhitidae, in which genus Cuvier had originally placed it. The specific name ''punctatus'' means "spotted", a reference to brown blotches and black spots this species has. Description The black spotted hawkfish has a snout which is not overly elongated and a deep body. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cirrhitidae
Cirrhitidae, the hawkfishes, are a family of marine perciform ray-finned fishes found in tropical seas and which are associated with coral reefs. Taxonomy The Cirrhitidae were first recognised as a family by the Scots-born Australian naturalist William Sharp Macleay in 1841. It is one of the 5 constituent families in the superfamily Cirrhitoidea which is classified in the suborder Percoidei of the order Perciformes. Within the Cirrhitoidea, the Cirrhitidae is probably the most basal family. They have been placed in the order Centrarchiformes by some authorities, as part of the superfamily Cirrhitoidea, however, the 5th edition of Fishes of the World does not recognise the Centrarchiformes. The name of the family is taken from that of the genus ''Cirrhitus'' which is derived from ''cirrhus'' meaning a "lock of hair" or "a barbel", thought to be a reference to lower, unbranched rays of the pectoral fins which Bernard Germain de Lacépède termed as “''barbillons''”, which m ...

Compound (linguistics)
In linguistics, a compound is a lexeme (less precisely, a word or sign) that consists of more than one stem. Compounding, composition or nominal composition is the process of word formation that creates compound lexemes. Compounding occurs when two or more words or signs are joined to make a longer word or sign. A compound that uses a space rather than a hyphen or concatenation is called an open compound or a spaced compound; the alternative is a closed compound. The meaning of the compound may be similar to or different from the meaning of its components in isolation. The component stems of a compound may be of the same part of speech—as in the case of the English word ''footpath'', composed of the two nouns ''foot'' and ''path''—or they may belong to different parts of speech, as in the case of the English word ''blackbird'', composed of the adjective ''black'' and the noun ''bird''. With very few exceptions, English compound words are stressed on their first component ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monotypic Fish Genera
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. In contrast, an oligotypic taxon contains more than one but only a very few subordinate taxa. Examples Just as the term ''monotypic'' is used to describe a taxon including only one subdivision, the contained taxon can also be referred to as monotypic within the higher-level taxon, e.g. a genus monotypic within a family. Some examples of monotypic groups are: Plants * In the order Amborellales, there is only one family, Amborellaceae and there is only one genus, '' Amborella'', and in this genus there is only one species, namely ''Amborella trichopoda.' ...

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] |
Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral surface of fish. The paired pelvic fins are homologous to the hindlimbs of tetrapods. Structure and function Structure In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays (lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. Pelvic fin structures can be extremely specialized in actinopterygians. Gobiids and lumpsuckers modify their pelvic fins into a sucker disk that allow them to adhere to the substrate or climb structures, such as waterfalls. In priapiumfish, males have modified their pelvic structures into a spiny copulatory device that grasps the female during mating.

Cirri
Giovanni Battista Cirri (1 October 1724 – 11 June 1808) was an Italian cellist and composer in the 18th century. Biography Cirri was born in Forlì in the Emilia-Romagna Region of Italy. He had his first musical training with his brother Ignazio (1711–1787) and was for a time organist at Forlì Cathedral. He also studied with Giovanni Battista Martini, in Bologna. In 1739 he was admitted to Holy Orders but decided to pursue a musical career. From 1759 he was a member of the "Accademia Filarmonica". He was in Paris during the first half of the 1760s and his first works were published including a "Symphony" which was performed at the Concert Spirituel on 5 April 1763. In 1764 he settled in London where he was employed as chamber musician to the Duke of York and Albany and director of music to the Duke of Gloucester and Edinburgh. His first public appearance in London on 16 May 1764 was as an accompanist to violinist Marcella. He played solos at the eight-year-old Moz ...

Specific Name (zoology)
In zoological nomenclature, the specific name (also specific epithet or species epithet) is the second part (the second name) within the scientific name of a species (a binomen). The first part of the name of a species is the name of the genus or the generic name. The rules and regulations governing the giving of a new species name are explained in the article species description. For example, the scientific name for humans is ''Homo sapiens'', which is the species name, consisting of two names: ''Homo'' is the " generic name" (the name of the genus) and ''sapiens'' is the "specific name". Historically, ''specific name'' referred to the combination of what are now called the generic and specific names. Carl Linnaeus, who formalized binomial nomenclature, made explicit distinctions between specific, generic, and trivial names. The generic name was that of the genus, the first in the binomial, the trivial name was the second name in the binomial, and the specific the proper term for ...
