Cociella Somaliensis
''Cociella somaliensis'' is a species of demersal, marine ray-finned fish belonging to the family Platycephalidae, the flatheads. It is found in the north western Indian Ocean. Taxonomy ''Cociella somaliensis'' was first formally described in 1996 by Leslie William Knapp with the type locality given as south of Ras Hafun Ras Hafun ( so, Ras Xaafuun, ar, رأس حـافـون, it, Capo Hafun), also known as Cape Hafun, is a promontory in the northeastern Bari region of Somalia. Jutting out into the Guardafui Channel, it constitutes the easternmost point in Afric ... in Somalia. These fishes were previously regarded as a population of the crocodile flathead (''C. crocodilus'') but were recognised as a valid species in 1996, although this species was only tentatively assigned to the genus ''Cociella''. The Specific name (zoology), specific name ''somaliensis'' refers to the type locality. Description ''Cociella somaliensis'' has 8 spines in the first dorsal fin with an additi ...

Cociella
''Cociella'' is a genus of marine ray-finned fishes belonging to the family Platycephalidae, the flatheads. These fishes are found in the Indo-Pacific region. Taxonomy ''Cociella'' was first proposed as a genus in 1940 by the Australian ichthyologist Gilbert Percy Whitley as a replacement for ''Cocius'' which had been put forward by David Starr Jordan and Carl Leavitt Hubbs in 1925 but this name was unavailable as it was preoccupied by the antlion genus '' Cocius''., described by the Spanish entomologist Longinos Navás in 1921. Jordan and Hubbs designated ''Platycephalus crocodilus'', a species described by Georges Cuvier in 1829 but no types are known, as the type species of their genus and Whitley retained it as the type species of the replacement. The genus is classified within the family Playcephalidae, the flatheads. The name of the genus, ''Cociella'', is a diminutive form of the original name coined by Jordan and Hubbs which is thought to be a latinisation of the Japanese ...

Caudal 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 ...

Lateral Line
The lateral line, also called the lateral line organ (LLO), is a system of sensory organs found in fish, used to detect movement, vibration, and pressure gradients in the surrounding water. The sensory ability is achieved via modified epithelial cells, known as hair cells, which respond to displacement caused by motion and transduce these signals into electrical impulses via excitatory synapses. Lateral lines serve an important role in schooling behavior, predation, and orientation. Fish can use their lateral line system to follow the vortices produced by fleeing prey. Lateral lines are usually visible as faint lines of pores running lengthwise down each side, from the vicinity of the gill covers to the base of the tail. In some species, the receptive organs of the lateral line have been modified to function as electroreceptors, which are organs used to detect electrical impulses, and as such, these systems remain closely linked. Most amphibian larvae and some fully aquatic adult ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
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 ...

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 ...

Demersal Fish
Demersal fish, also known as groundfish, live and feed on or near the bottom of seas or lakes (the demersal zone).Walrond Carl . "Coastal fish - Fish of the open sea floor"Te Ara - the Encyclopedia of New Zealand. Updated 2 March 2009 They occupy the sea floors and lake beds, which usually consist of mud, sand, gravel or rocks. In coastal waters they are found on or near the continental shelf, and in deep waters they are found on or near the continental slope or along the continental rise. They are not generally found in the deepest waters, such as abyssal depths or on the abyssal plain, but they can be found around seamounts and islands. The word ''demersal'' comes from the Latin ''demergere'', which means ''to sink''. Demersal fish are bottom feeders. They can be contrasted with pelagic fish which live and feed away from the bottom in the open water column. Demersal fish fillets contain little fish oil (one to four percent), whereas pelagic fish can contain up to 30 percent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crocodile Flathead
The crocodile flathead (''Cociella crocodilus'') is a species of marine ray-finned fish belonging to the family Platycephalidae, the flatheads. It is found in the western Pacific Ocean. Taxonomy The crocodile flathead was first formally described as ''Platycephalus crocodilus'' in 1829 by the French zoologist Georges Cuvier, the species was not described from a type specimen, it was based on an illustration and so is an iconotype. In 1925 David Starr Jordan and Carl Leavitt Hubbs proposed a new genus, ''Cocius'', and named ''P. crocodilus'' as its type species. However, this was preoccupied by an antlion named by the Spanish entomologist Longinos Navás in 1921, and in 1940 Gilbert Percy Whitley proposed a new name for this genus ''Cociella'', a diminutive of Jordan and Hubbs original name. The crocodile flathead was considered to have a wide Indo-Pacific distribution but in 1996 Leslie W. Knapp described three new species and removed a fourth '' C. punctata'' from being ...

Ras Hafun
Ras Hafun ( so, Ras Xaafuun, ar, رأس حـافـون, it, Capo Hafun), also known as Cape Hafun, is a promontory in the northeastern Bari region of Somalia. Jutting out into the Guardafui Channel, it constitutes the easternmost point in Africa. The area is situated near the Cape Guardafui headland. It is joined to the mainland at the town of Foar, by a sand spit long, in width, and above sea level. The fishing town of Hafun is located on the promontory, east of the sand spit. Ras Hafun and its line of latitude separate the Guardafui Channel to its north, from the Somali Sea to its south. History Antiquity and Middle Ages Ras Hafun is home to numerous ancient structures and ruins. The peninsula is believed to be the location of the old trade emporium of Opone. The latter is mentioned in the anonymous ''Periplus of the Erythraean Sea'', written in the first century CE. Opone is described therein as a busy port city, strategically located on the trade route that spanned ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
