Aphyonidae
Aphyonidae is a family (biology), family of eel-like fishes in the order Ophidiiformes. They are found in tropical and subtropical waters throughout the world. They are deep-sea fishes, living between and depth. Description and biology Aphyonids are small fishes, typically about long when fully grown. They have transparent, gelatinous skin, which lacks any scale (anatomy), scales. The dorsal fin, dorsal, caudal fin, caudal and anal fins are united into a single ribbon. Most species are neoteny, neotenic, showing a number of features as adults that are more commonly associated with fish larvae. For example, the skeleton is only partially calcified, and the muscles and gills are underdeveloped. The eyes, nasal organ and lateral line are also reduced, and they lack a swim bladder. The aphyonids are viviparous, giving birth to live young. The males bundle their sperm into small sacs (spermatophores), so that they can be stored for extended periods. This allows them to mate with im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barathronus
''Barathronus'' is a genus of deep-Deep sea, sea fish that are placed in the family Aphyonidae (blind cusk eels) or family Bythitidae (brotulas), depending on the source. Life cycle ''Barathronus'' are viviparous deep-sea fish. However, a juvenile ''Barathronus pacificus'' has been recorded in shallow waters. Based on the stable oxygen isotope composition of otoliths, at least one species, ''Barathronus maculatus'', has a pelagic larval stage, followed by an ontogenetic vertical migration to deeper waters. Species There are currently 10 recognized species in this genus, although the exact species differ between the FishBase and the Catalog of Fishes: * ''Barathronus affinis'' August Bernhard Brauer, A. B. Brauer, 1906 * ''Barathronus bicolor'' George Brown Goode, Goode & Tarleton Hoffman Bean, T. H. Bean, 1886 * ''Barathronus bruuni'' Jørgen G. Nielsen, J. G.

Aphyonus
''Aphyonus'' is a genus of blind cusk eels from the family Aphyonidae. It contains four species. A sampling of specimens of ''Aphyonus'' showed that the type species of ''Aphyonus'', '' A. gelatinosus'', was not closely related to the other known species in the genus, and a new genus '' Paraphyonus'' was named for these, including two newly identified species. The result of this classification is that ''Aphyonus'' would be a monotypic In biology, a monotypic taxon is a taxonomic group (taxon) that contains only one immediately subordinate taxon. A monotypic species is one that does not include subspecies or smaller, infraspecific taxa. In the case of genera, the term "unisp ... genus.

Paraphyonus
''Paraphyonus'' is a genus of blind cusk eels found in the Atlantic, Indian and Pacific Oceans. This genus was created for species formerly classified under ''Aphyonus'' when sampling of specimens showed that the type species of ''Aphyonus'', '' A. gelatinosus'', was not closely related to the other known species in the genus, including the newly identified species ''P. iselini'' and ''P. merretti''. This work also brought ''Barathronus solomonensis'' into the new genus. The result of this classification is that ''Aphyonus'' would be a monotypic genus. Species There are currently 6 recognized species in this genus: * '' Paraphyonus bolini'' ( J. G. Nielsen, 1974) * '' Paraphyonus brevidorsalis'' ( J. G. Nielsen, 1969) * '' Paraphyonus iselini'' J.

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] |
Muscle
Muscle is a soft tissue, one of the four basic types of animal tissue. There are three types of muscle tissue in vertebrates: skeletal muscle, cardiac muscle, and smooth muscle. Muscle tissue gives skeletal muscles the ability to muscle contraction, contract. Muscle tissue contains special Muscle contraction, contractile proteins called actin and myosin which interact to cause movement. Among many other muscle proteins, present are two regulatory proteins, troponin and tropomyosin. Muscle is formed during embryonic development, in a process known as myogenesis. Skeletal muscle tissue is striated consisting of elongated, multinucleate muscle cells called muscle fibers, and is responsible for movements of the body. Other tissues in skeletal muscle include tendons and perimysium. Smooth and cardiac muscle contract involuntarily, without conscious intervention. These muscle types may be activated both through the interaction of the central nervous system as well as by innervation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gill
A gill () is a respiration organ, respiratory organ that many aquatic ecosystem, aquatic organisms use to extract dissolved oxygen from water and to excrete carbon dioxide. The gills of some species, such as hermit crabs, have adapted to allow respiration on land provided they are kept moist. The microscopic structure of a gill presents a large surface area to the external environment. Branchia (: branchiae) is the zoologists' name for gills (from Ancient Greek ). With the exception of some aquatic insects, the filaments and lamella (surface anatomy), lamellae (folds) contain blood or Coelom#Coelomic fluid, coelomic fluid, from which gases are exchanged through the thin walls. The blood carries oxygen to other parts of the body. Carbon dioxide passes from the blood through the thin gill tissue into the water. Gills or gill-like organs, located in different parts of the body, are found in various groups of aquatic animals, including Mollusc, molluscs, crustaceans, insects, fish, a ...

David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he served as president of Indiana University Bloomington, Indiana University from 1885 to 1891. Jordan was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration", asserting that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and education Jordan was born in Gainesville (town), New York, Gainesville, New York, and grew up on a farm in upstate New York. His parents made an unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, ...
