Rhamphocottidae
Rhamphocottidae is a family of ray-finned fishes belonging to the superfamily Cottoidea, the sculpins. The species in this family occur in the North Pacific Ocean. Taxonomy Rhamphocottidae was first proposed as a family by the American ichthyologists David Starr Jordan and Charles Henry Gilbert in 1883. The family was regarded as monotypic until 2014 when the family Ereunidae was synonymised with it. This family is classified within the superfamily Cottoidea in the suborder Cottoidei in the order Scorpaeniformes in the 5th edition of '' Fishes of the World'' but other authorities states that if Scorpaeniformes is excluded from Perciformes then Perciformes is recovered as paraphyletic and so classify this family within the infraorder Cottales within the suborder Cottoidei of the Perciformes. Within the Cottoidea the Ramphocottidae is the sister taxon to all the other groups. Genera Rhamphocottidae contains the following genera: Characteristics Rhamphocottidae sculpins have ...

Grunt Sculpin
The grunt sculpin or grunt-fish (''Rhamphocottus richardsonii'') is a small fish mainly found in the eastern Pacific Ocean. The grunt sculpin generally remains close to shore and is often found in empty giant barnacle shells. The common name comes from reports that the fish vibrate or "grunt" when held. Its defining feature is its tendency to “hop” along the ocean floor on its orange fins. The short, stout body of the grunt sculpin has a long, small mouth which is adapted for eating smaller prey. Taxonomy It is a member of the class Actinopterygii, the ray-finned fishes. It is further classified into the order Scorpaeniformes, commonly known as the mail-cheeked fishes. The superfamily Cottoidea which is classified within this order includes ''R. richardsonii'' and all other sculpins. However, the grunt sculpin was regarded as the only member of the family Rhamphocottidae until the Ereuniidae was synonymized with Rhamphocottidae. The records fron the western North Pacific ar ...

Sculpin
A sculpin is a type of fish that belongs to the superfamily Cottoidea in the order Scorpaeniformes.Kane, E. A. and T. E. Higham. (2012)Life in the flow lane: differences in pectoral fin morphology suggest transitions in station-holding demand across species of marine sculpin.''Zoology'' (Jena) 115(4), 223-32. As of 2006, this superfamily contains 7 families, 94 genera, and 387 species. Sculpins occur in many types of habitat, including ocean and freshwater zones. They live in rivers, submarine canyons, kelp forests, and shallow littoral habitat types, such as tidepools. Sculpins are benthic fish, dwelling on the bottoms of water bodies. Their pectoral fins are smooth on the upper edge and webbed with sharp rays along the lower edge, a modification that makes them specialized for gripping the substrate. This adaptation helps the fish anchor in fast-flowing water. The sculpin normally grows to about four inches long. Families and subfamilies Families include: * Jordaniidae Sta ...

Scorpaeniformes
The Scorpaeniformes are a diverse order of 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 pre operculum, to which it is connected in most species. Scorpaeniform fishes are 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 and caudal fins. Most species are less than in length, but the full size range of the order varies from the velvetfishes belonging to the family Aploactin ...

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 the superfamilies of ''Fishes of the World'' as infraorders. Subdivisions The Cottoidei is divided into the following superfamilies and families: * Super ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Perciformes
Perciformes (), also called the Percomorpha or Acanthopteri, is an order or superorder of ray-finned fish. If considered a single order, they are the most numerous order of vertebrates, containing about 41% of all bony fish. Perciformes means "perch-like". Perciformes is an Order within the Clade Percomorpha consisting of "perch-like" Percomorphans. This group comprises over 10,000 species found in almost all aquatic ecosystems. The order contains about 160 families, which is the most of any order within the vertebrates. It is also the most variably sized order of vertebrates, ranging from the ''Schindleria brevipinguis'' to the marlin in the genus ''Makaira''. They first appeared and diversified in the Late Cretaceous. Among the well-known members of this group are perch and darters (Percidae), sea bass and groupers (Serranidae). Characteristics The dorsal and anal fins are divided into anterior spiny and posterior soft-rayed portions, which may be partially or compl ...

John Otterbein Snyder
John Otterbein Snyder (August 14, 1867 – August 19, 1943) was an American ichthyologist and professor of zoology at Stanford University. History As a student he met David Starr Jordan who inspired him to enter zoology. He eventually became a zoology instructor at Stanford University and served there from 1899 until 1943. He went on several major collecting expeditions aboard the in the early 1900s and organized the U.S. National Museum's fish collection in 1925. The same year he also declined the directorship there so he could return to Stanford. He was a long-term member of the California Academy of Sciences and worked for the California Bureau of Fisheries. He wrote many articles and papers as well as describing several new species of sharks. San Francisco Bay In 1905, Snyder, then Assistant Professor of Zoology at Stanford, published ''Notes on the fishes of the streams flowing into San Francisco Bay'' in ''Report of the Commissioner of Fisheries to the Secretary of Comme ...

Taxa Named By David Starr Jordan
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's system in '' Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first made widely available in 1805 in the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Henry Gilbert
Charles Henry Gilbert (December 5, 1859 in Rockford, Illinois – April 20, 1928 in Palo Alto, California) was a pioneer ichthyologist and Fisheries science, fishery biologist of particular significance to natural history of the western United States. He collected and studied fishes from Central America north to Alaska and described many new species. Later he became an expert on Pacific salmon and was a noted conservation movement, conservationist of the Pacific Northwest. He is considered by many as the intellectual founder of American fisheries biology. He was one of the 22 "pioneer professors" (founding faculty) of Stanford University. Early life and education Born in Rockford, Illinois, Gilbert spent his early years in Indianapolis, Indiana, where he came under the influence of his high school teacher, David Starr Jordan (1851‒1931). When Jordan became Professor of Natural History at Butler University in Indianapolis, Gilbert followed and received his B.A. degree in 187 ...

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.
