Spinyfin
Spinyfins are a family, Diretmidae, of trachichthyform fishes. The family name is derived from the type genus, '' Diretmus'', from Greek, ''di'' meaning "two" and ''eretmos'' meaning "oar". They are found worldwide in deep waters, as deep as . As the common name implies, spinyfins have heavy spines along their fins. They have deep, compressed bodies, and almost vertically aligned mouths. They are dark silver in colour, and reach up to in length.

Diretmus
The silver spinyfin (''Diretmus argenteus'') is a spinyfin of the genus ''Diretmus'', found around the world except the Mediterranean, at depths down to 2,000 m. It belongs to the monotypic genus ''Diretmus''. Their length is between 30 and 40 cm. The silver spinyfin is a widely distributed but rare species with a flattened disc-shaped body with a sharp scute-covered edge on the belly. A large upturned mouth and huge eye dominate the front half of the disc and a small truncate caudal fin projects from the other. They are oviparous and the larvae spend time in the plankton. ''D. argenteus'' has 38 opsin genes for the rods in its retinas, suggesting that they can see in color in very low light conditions. The silver spinyfin has the highest number of visual opsins of any vertebrate according to a research study. It has small spiny scales but no lateral line The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used t ...

Diretmichthys
Parin's spinyfin, Parin's spinyfish, black discfish, black spinyfin, or spiny discfish (''Diretmichthys parini'') is a spinyfin of the monotypic genus ''Diretmichthys''. Adults are found in oceans at depths of between 500 m to 2100 m. Its length is up to 40 cm. Distribution Parin's spinyfish is a rare species but is widely distributed. It is found in the Western Pacific, Western Indian and Eastern Atlantic Oceans. ''Diretmichthys parini'' is also found in the Caribbean Sea. Its latitudinal range is 40°N–40°S. In the month-long NORFANZ Expedition of 2003 which was examining the biodiversity of the seamounts and slopes of the Norfolk Ridge near New Zealand, thirteen specimens averaging 900g (2 lb), were collected from nine locations.

Type Genus
In biological taxonomy, the type genus is the genus which defines a biological family and the root of the family name. Zoological nomenclature According to the International Code of Zoological Nomenclature, "The name-bearing type of a nominal family-group taxon is a nominal genus called the 'type genus'; the family-group name is based upon that of the type genus." Any family-group name must have a type genus (and any genus-group name must have a type species, but any species-group name may, but need not, have one or more type specimens). The type genus for a family-group name is also the genus that provided the stem to which was added the ending -idae (for families). :Example: The family name Formicidae has as its type genus the genus ''Formica'' Linnaeus, 1758. Botanical nomenclature In botanical nomenclature, the phrase "type genus" is used, unofficially, as a term of convenience. In the '' ICN'' this phrase has no status. The code uses type specimens for ranks up to fam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greek Language
Greek ( el, label=Modern Greek, Ελληνικά, Elliniká, ; grc, Ἑλληνική, Hellēnikḗ) is an independent branch of the Indo-European family of languages, native to Greece, Cyprus, southern Italy (Calabria and Salento), southern Albania, and other regions of the Balkans, the Black Sea coast, Asia Minor, and the Eastern Mediterranean. It has the longest documented history of any Indo-European language, spanning at least 3,400 years of written records. Its writing system is the Greek alphabet, which has been used for approximately 2,800 years; previously, Greek was recorded in writing systems such as Linear B and the Cypriot syllabary. The alphabet arose from the Phoenician script and was in turn the basis of the Latin, Cyrillic, Armenian, Coptic, Gothic, and many other writing systems. The Greek language holds a very important place in the history of the Western world. Beginning with the epics of Homer, ancient Greek literature includes many works of lasting impo ...
