Stichaeus
''Stichaeus'' is a genus of marine ray-finned fishes belonging to the family Stichaeidae, the pricklebacks or shannies. These fishes are mainly found in the North Pacific Ocean with one species in the Arctic and western North Atlantic Oceans. Taxonomy ''Stichaeus'' was first proposed as a monospecific genus in 1836 by the Danish zoologist Johan Reinhardt with ''Blennius punctatus'', which was described by Johan Christian Fabricius in 1780 from western Greenland, designated as the type species. This genus is classified within the subfamily Stichaeinae of the Zoarcoid family Stichaeidae. Species ''Stichaeus'' contains 6 extant species and 2 known extinct species, as follows: † means extinct Etymology The genus name, ''Stichaeus'' means "to set in a row", and is presumed to refer to the row of 5 or 6 circular spots on the dorsal fin. Characteristics ''Stichaeus'' species have moderately elongated, laterally compressed bodies which are covered in tiny cycloid scales, altho ...

Arctic Shanny
The Arctic shanny (''Stichaeus punctatus'') is a species of marine ray-finned fish belonging to the family Stichaeidae, the pricklebacks and shannies. This species occurs in the North Pacific, Arctic and western North Atlantic Oceans. Taxonomy The Arctic shanny was first formally described in 1780 as ''Blennius punctatus'' by the Danish zoologist Johan Christian Fabricius, giving its type locality as Western Greenland. When Johan Reinhardt proposed the genus '' Stichaeus'' he designated ''Blennius punctatus'' as its type species. The specific name ''punctatus'' means spotted, a reference to the 5 or 6 spots on the dorsal fin. Subspecies Some authorities recognise two subspecies of the Arctic shanny: The nominate subspecies is found in the northern western Atlantic and Pacific Oceans and is sympatric with ''S.p. pulcherrimus'' in the Sea of Okhtosk and this subspecies may be a valid, distinct species. Description The Arctic shanny has the moderately elongated, laterally compres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stichaeinae
Stichaeinae is a subfamily of marine ray-finned fishes, Taxonomy (biology), classified within the family Stichaeidae, the pricklebacks or shannies. These fishes are found in the North Pacific, Arctic and North Atlantic Oceans. Taxonomy Stichaeinae contains the type taxon of the family Stichaeidae, the Arctic shanny (''Stichaeus punctatus''), and the name is based on Theodore Gill’s 1864 name for the family. The name of the subfamily comes from that of its type genus ''Stichaeus'', which means “set in a row”, which may be an allusion to the row of black spots on the dorsal fin, dorsal fins of the species in that genus. Genera Stichaeinae contains the following genera: ''Dinogunellus'' Solomon Herzenstein, Herzenstein, 1890 is treated as a vaild genus by ''Catalog of Fishes'' but ''Fishbase'' does not and treats the 3 species classified within it as belonging to the genus ''Stichaeus''.

Stichaeidae
Stichaeidae, the pricklebacks or shannies, are a family of marine ray-finned fishes in the suborder Zoarcoidei of the order Scorpaeniformes. Most species are found in the North Pacific Ocean with a few in the North Atlantic Ocean. Taxonomy Stichaeidae was first proposed as a family in 1864 by the American zoologist Theodore Gill, although he called it the Stichaeoidae. The 5th edition of ''Fishes of the World'' classifies this family within the suborder Zoarcoidei, within the order Scorpaeniformes. Other authorities classify this family in the infraorder Zoarcales wihin the suborder Cottoidei of the Perciformes because removing the Scorpaeniformes from the Perciformes renders that taxon non monophyletic. ''Fishes of the World'' mentions six subfamilies but does not assign genera to the subfamilies while other authorities split the Cebidichthyidae, Opisthocentridae, Lumpenidae and Neozoarcidae from the Sitchaeidae as valid families. The genera which are classified within the fami ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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 aquati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palatine Bone
In anatomy, the palatine bones () are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat. Together with the maxillae, they comprise the hard palate. (''Palate'' is derived from the Latin ''palatum''.) Structure The palatine bones are situated at the back of the nasal cavity between the maxilla and the pterygoid process of the sphenoid bone. They contribute to the walls of three cavities: the floor and lateral walls of the nasal cavity, the roof of the mouth, and the floor of the orbits. They help to form the pterygopalatine and pterygoid fossae, and the inferior orbital fissures. Each palatine bone somewhat resembles the letter L, and consists of a horizontal plate, a perpendicular plate, and three projecting processes—the pyramidal process, which is directed backward and lateral from the junction of the two parts, and the orbital and sphenoidal processes, which surmount the vertical part, and are separated by ...

Vomer
The vomer (; lat, vomer, lit=ploughshare) is one of the unpaired facial bones of the skull. It is located in the midsagittal line, and articulates with the sphenoid, the ethmoid, the left and right palatine bones, and the left and right maxillary bones. The vomer forms the inferior part of the nasal septum in humans, with the superior part formed by the perpendicular plate of the ethmoid bone. The name is derived from the Latin word for a ploughshare and the shape of the bone. In humans The vomer is situated in the median plane, but its anterior portion is frequently bent to one side. It is thin, somewhat quadrilateral in shape, and forms the hinder and lower part of the nasal septum; it has two surfaces and four borders. The surfaces are marked by small furrows for blood vessels, and on each is the nasopalatine groove, which runs obliquely downward and forward, and lodges the nasopalatine nerve and vessels. Borders The ''superior border'', the thickest, presents a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cycloid Scale
A fish scale is a small rigid plate that grows out of the skin of a fish. The skin of most jawed fishes is covered with these protective scales, which can also provide effective camouflage through the use of reflection and colouration, as well as possible hydrodynamic advantages. The term ''scale'' derives from the Old French , meaning a shell pod or husk. Scales vary enormously in size, shape, structure, and extent, ranging from strong and rigid armour plates in fishes such as shrimpfishes and boxfishes, to microscopic or absent in fishes such as eels and anglerfishes. The morphology of a scale can be used to identify the species of fish it came from. Scales originated within the jawless ostracoderms, ancestors to all jawed fishes today. Most bony fishes are covered with the cycloid scales of salmon and carp, or the ctenoid scales of perch, or the ganoid scales of sturgeons and gars. Cartilaginous fishes (sharks and rays) are covered with placoid scales. Some speci ... [...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 r ...
