Nototheniops
''Nototheniops'' is a genus of marine ray-finned fishes belonging to the family Nototheniidae, the notothens or cod icefishes. The species in this genus are native to the Southern Ocean. Taxonomy ''Nototheniops'' Was first formally described as a subgenus of the genus '' Lepidonotothen'' in 1976 by the Soviet ichthyologist Arkady Vladimirovich Balushkin. The genus has been considered to be monotypic by some authorities with ''N. larseni'' as the only species. Some authorities place this genus in the subfamily Nototheniinae, but the 5th edition of ''Fishes of the World'' does not include subfamilies in the Nototheniidae. The specific name is a compound of ''Notothenia'', which this genus is closely related to and ''ops'' meaning “eyes” referring to its larger eyes. Species The recognized species in this genus are: * '' Nototheniops larseni'' ( Lönnberg, 1905) * '' Nototheniops loesha'' (Balushkin 1976) * '' Nototheniops nybelini'' ( Balushkin, 1976) * '' Nototheniops tchizh ...

Nototheniops Larseni
The painted notie (''Lepidonotothen larseni''), or painted notothen, is a species of marine ray-finned fish, belonging to the family Nototheniidae, the notothens or cod icefishes. It is native to the Southern Ocean. Taxonomy The painted notie was first formally described in 1905 as ''Notothenia larseni'' by the Swedish zoologist Einar Lönnberg with the type locality given as Shag Rocks, South Georgia Island. Some authorities consider the genus ''Nototheniops'' to be monotypic with this species being the only species and all the others, ''N. loesha'', ''N. nybelini'' and ''N. tchizh'' being its synonyms, arguing that these seemingly allopatric taxa show as much variation within their populations as they do between each other. The specific name honours Carl Anton Larsen who was the chief navigator on the Swedish Antarctic Expedition which collected the type specimen. Description The painted notie has a body which has a depth which fits into its standard length 4.5-7.7 times. I ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nototheniidae
: ''In some scientific literature, the term "cod icefish" is used to identify members of this family. This should not be confused with the term "icefish," which refers to the "white-blooded" fishes of the family Channichthyidae. See Icefish (other).'' Nototheniidae, the notothens or cod icefishes, is a family of ray-finned fishes, part of the suborder Notothenioidei which is traditionally placed within the order Perciformes. They are largely found in the Southern Ocean. Taxonomy Nototheniidae was described as a family in 1861 by the German-born British ichthyologist Albert Günther with the type genus being ''Notothenia'' which had been described in 1844 by Sir John Richardson with the species ''Notothenia coriiceps'' which Richardson had also described in 1844 subsequently being designated as the type in 1862 by Theodore Nicholas Gill. The name ''Notothenia'' means “coming from the south”, a reference to the Antarctic distribution of the genus. They are traditio ...

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.

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.

Pectoral 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 ...

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] |
Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies. These data are used in many areas of ichthyology, including taxonomy and fisheries biology. Overall length * Standard length (SL) is the length of a fish measured from the tip of the snout to the posterior end of the last vertebra or to the posterior end of the midlateral portion of the hypural plate. Simply put, this measurement excludes the length of the caudal (tail) fin. * Total length (TL) is the length of a fish measured from the tip of the snout to the tip of the longer lobe of the caudal fin, usually measured with the lobes compressed along the midline. It is a straight-line measure, not measured over the curve of the body. Standard length measurements are used with Teleostei (most bony fish), while total length measurements are used with Myxini (hagfish), Petromyzontiformes (lampreys), and (usually) Elasmobranchii (sharks and rays), as well as some other fishes.
