Microcottus Sellaris
''Microcottus'' is a small genus of marine ray-finned fishes belonging to the family Cottidae, the typical sculpins. These fishes are found in the northern Pacific Ocean. Taxonomy ''Microcottus'' was first proposed as a genus in 1940 by the Soviet zoologist Peter Schmidt with ''Acanthocottus sellaris'' as its type species by monotypy. ''A. sellaris'' has originally been described by Charles Henry Gilbert from Bristol Bay in Alaska. The 5th edition of ''Fishes of the World'' classifies this genus in the subfamily Cottinae of the family Cottidae but other authorities classify it in the subfamily Myoxocephalinae of the family Psychrolutidae, although others place the subfamily Myoxocephalinae within the Cottidae. Etymology ''Microcottus'' prefixes '' Cottus'', the type genus of the family Cottidae, with ''micro'', meaning "small", alluding to the small size of ''M. sellaris'' in comparison to the related genus ''Myoxocephalus''. Species ''Microcottus'' is a small genus which con ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peter Yulevich Schmidt
Peter Yulievich Schmidt (born 23 December 1872, St. Petersburg, died 25 November 1949, Leningrad) was a Russian and Soviet zoologist, ichthyologist and museum curator. Peter Yulievich Schmidt attended the gymnasium of KI May before studying at the Physics and Mathematics Faculty of St. Petersburg University, from where he graduated in 1895. He was engaged in the laboratory of Professor V.M. Shimkevich and V.T. Shevyakov. He travelled through Semirechiy in 1899-1902. In 1908-1910 he participated in the Kamchatka expedition of F. P.

Total Length
Fish measurement is the measuring of individual fish and various parts of their anatomies, for data used in many areas of ichthyology, including taxonomy and fishery 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. 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 (shark Sharks are a group of elasmobranch cartilaginous fish characterized by a ...

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 play an important role in schooling behavior, predation, and orientation. Early in the evolution of fish, some of the sensory organs of the lateral line were modified to function as the electroreceptors called ampullae of Lorenzini. The lateral line system is ancient and basal to the vertebrate clade, as it is found in fishes that diverged over 400 million years ago. Function The lateral line system allows the detection of movement, vibration, and pressure gradients in the water surrounding an animal. It plays an essential role in orientation, predation, and fish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palatine Bone
In anatomy, the palatine bones (; derived from the Latin ''palatum'') are two irregular bones of the facial skeleton in many animal species, located above the uvula in the throat. Together with the maxilla, they comprise the hard palate. 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 a deep notch, the s ...

Pelvic Fin
Pelvic fins or ventral fins are paired fins located on the ventral (belly) surface of fish, and are the lower of the only two sets of paired fins (the other being the laterally positioned pectoral fins). The pelvic fins are homologous to the hindlimbs of tetrapods, which evolved from lobe-finned fish during the Middle Devonian. 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
