Hexagrammos
''Hexagrammos'' is a genus of marine ray-finned fishes belonging to the Family (biology), family Hexagrammidae, the greenlings. These fishes are found in the north Pacific Ocean. Taxonomy ''Hexagrammos'' was first proposed as a monospecific genus in 1810 by the German naturalist Wilhelm Gottlieb Tilesius von Tilenau, Tilesius when he Species description, described ''Hexagrammos asper'' giving its Type locality (biology), type locality as Petropavlovsk-Kamchatsky, Petropavlovsk in Kamchatka. Tilesius's original name was subsequently incorrectly changed to ''H. stelleri'' and this was the name which became settled on in the literature that followed and this use and practice means it that it is impractical to bring ''H. asper'' into common use. The genus is the only genus in the monogeneric subfamily Hexagramminae, within the family Hexagrammidae, part of the suborder Cottoidei within the Order (biology), order Scorpaeniformes. The painted greenling (''Oxylebius pictus''), while pre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hexagrammidae
Hexagrammidae, the greenlings, is a Family (biology), family of marine ray-finned fishes belonging to the suborder Cottoidei in the Order (biology), order Perciformes. These fishes are found in the North Pacific Ocean. Taxonomy Hexagrammidae was first proposed as a family in 1888 by the American ichthyologist David Starr Jordan. The 5th edition of ''Fishes of the World'' classifies this family as the only family in the Monotypic taxon, monotypic Superfamily (biology), superfamily Hexagrammoidea within the suborder Cottoidei of the diverse order Scorpaeniformes. Other workers have found that if the Scorpaeniformes, as delimited in ''Fishes of the World'', is not included in the Perciformes it renders the Perciformes paraphyletic. These workers retain the Cottoidei as a suborder within the Perciformes while reclassifying Hexagrammoidea as the infraorder Hexagrammales. The family Zaniolepididae has been included within the Hexagrammidae, as the subfamilies Zaniolepidinae and Oxylebi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Painted Greenling
The painted greenling (''Oxylebius pictus'') is a species of marine ray-finned fish belonging to the family Zaniolepididae, which includes this species and the combfishes. It is endemic to the northeast Pacific Ocean. It is the only species in the genus ''Oxylebius''. Taxonomy The painted greenling was first formally described in 1862 by the American biologist Theodore Gill with the type locality given as San Francisco. Gill classified it in the monospecific genus ''Oxylebius'' and proposed the monotypic subfamily Oxylebinae which was placed in the family Hexagrammidae, although the subfamily was placed in the Zaniolepididae in the 6th edition of ''Fishes of the World'' and other authorities. Etymology The painted greenling's generic name ''Oxylebius'' prefixes ''oxy'' meaning "sharp", alluding to the sharper snout of this species in comparison to ''Zaniolepis'', to ''lebius'' which Gill did not explain. However Jordan and Evermann gave their view that ''lebius'' is a Synon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, ...

Petropavlovsk-Kamchatsky
Petropavlovsk-Kamchatsky (, ) is a city and the administrative center of Kamchatka Krai, Russia. It is located in the Far East of the country and lies along the coast of Avacha Bay by the Pacific Ocean, nearby Khalaktyrskoye Lake. As of the 2021 census, it had a population of 164,900. The city is widely known simply as ''Petropavlovsk'' (literally "city of Peter and Paul"). The adjective ''Kamchatsky'' ("Kamchatkan") was added to the official name in 1924. History Origins Cossack units visited the area from 1697. The explorer and navigator Captain Vitus Bering (a Danish-born Russian) is considered to have founded the city in 1740, although navigator had laid the foundation a few months earlier. Bering reached Avacha Bay in late 1740 and in his capacity as the superior officer, named the new settlement "Petropavlovsk" (Peter and Paul) after his two ships, the ''Saint Peter'' and the '' Saint Paul'', which had been built in Okhotsk for his second expedition (1733–42).

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch people, Dutch patrician, Zoology, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), illustrated by Pauline Rifer de Courcelles, Pauline Knip. He wrote ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna jap ...

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] |
Scorpaeniformes
The Scorpaeniformes are a diverse Order (biology), order of Actinopterygii, ray-finned fish, including the lionfishes and sculpins, but have also been called the Scleroparei. It is one of the five largest orders of bony fishes by number of species, with over 1,320. They are known as "mail-cheeked" fishes due to their distinguishing characteristic, the suborbital stay: a backwards extension of the third circumorbital bone (part of the lateral head/cheek skeleton, below the eye socket) across the cheek to the preoperculum (fish), operculum, to which it is connected in most species. Scorpaeniform fishes are carnivore, carnivorous, mostly feeding on crustaceans and on smaller fish. Most species live on the sea bottom in relatively shallow waters, although species are known from deep water, from the midwater, and even from fresh water. They typically have spiny heads, and rounded pectoral fin, pectoral and caudal fins. Most species are less than in length, but the full size range o ...

Order (biology)
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cottoidei
Cottoidei is a suborder of ray-finned fishes which, according to the 5th edition of ''Fishes of the World'', is placed within the order Scorpaeniformes, alongside the scorpionfishes, flatheads, eelpouts, sticklebacks and related fishes. Taxonomy Cottoidei was first proposed as a taxonomic grouping in 1835 by the Swiss-American zoologist Louis Agassiz. The 5th edition of ''Fishes of the World'' classifies the Cottoidei as a suborder of the order Scorpaeniformes. Other workers have found that if the Scorpaeniformes, as delimited in ''Fishes of the World'', is not included in the Perciformes it renders the Perciformes paraphyletic. These workers retain the Cottoidei as a suborder within the Perciformes but include the zoarcoids and Sticklebacks and allies as the infraorders Zoarcales and Gasterosteales while reclassifying most superfamilies of ''Fishes of the World'' as infraorders. Subdivisions The Cottoidei is divided into the following superfamilies and families: * Superfa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
