Agonidae
Agonidae is a family of small, bottom-dwelling, cold-water marine fish. Common names for members of this family include poachers, Irish lords, sea ravens, alligatorfishes, starsnouts, hooknoses, and rockheads. They are notable for having elongated bodies covered by scales modified into bony plates, and for using their large pectoral fins to move in short bursts. The family includes about 59 species in some 25 genera, some of which are quite widespread. The pelvic fins are nearly vestigial, typically consisting of one small spine and a few rays. The swim bladder is not present. At in length, the dragon poacher (''Percis japonica'') is the largest member of the family, while '' Bothragonus occidentalis'' is long as an adult; most are in the 20–30 cm range. Agonidae species generally feed on small crustaceans and marine worms found on the bottom. Some species camouflage Camouflage is the use of any combination of materials, coloration, or illumination for conce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Perciformes
Perciformes (), also called the Acanthopteri, is an order or superorder of ray-finned fish in the clade Percomorpha. ''Perciformes'' means " perch-like". Among the well-known members of this group are perches and darters ( Percidae), and also sea basses and groupers (Serranidae). This order contains many familiar freshwater temperate and tropical marine fish groups, but also extremophiles that have successfully colonized both the North and South Poles, as well as the deepest depths of the ocean. Taxonomy Formerly, this group was thought to be even more diverse than it is thought to be now, containing about 41% of all bony fish (about 10,000 species) and about 160 families, which is the most of any order within the vertebrates. However, many of these other families have since been reclassified within their own orders within the clade Percomorpha, significantly reducing the size of the group. In contrast to this splitting, other groups formerly considered distinct, such as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cottoidea
A sculpin is a type of fish that belongs to the superfamily Cottoidea in the order Perciformes.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. Families and subfamilies Families include: * Jordaniidae Starks, 1895 * Rhamphocottidae Jordan & Gilbert, 1883 * Scorpaenichthyidae Jordan & Evermann, 1898 * Agonidae Swainson, 1839 ** Hemilepidontinae Jordan & Evermann, 1898 ** Hemitripterinae Gill, 1856 ** Bothragoninae Lindberg, 1971 ** Hypsagoninae Gill, 1861 ** Anoplagoninae Gill, 1861 ** Brachyopsinae Jordan & Evermann, 1898 ** Agoninae Sw ...

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] |
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 ...

Infraorder
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between Family_(biology), family and Class_(biology), 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, ...

Paraphyletic
Paraphyly is a taxonomic term describing a grouping that consists of the grouping's last common ancestor and some but not all of its descendant lineages. The grouping is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic grouping (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of synapomorphies and symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term received currency during the debates of the 1960s and 1970s accompanying the rise of cladistics, having been coined by zoologist Willi Hennig to apply to well-known taxa like Reptilia (reptiles), which is paraphyletic with respect to birds. Reptilia contains the last common ancestor of reptiles and all descendants of that ancestor exc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cottidae
The Cottidae are a family of fish in the superfamily Cottoidea, the sculpins. It is the largest sculpin family, with about 275 species in 70 genera.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. They are referred to simply as cottids to avoid confusion with sculpins of other families. Cottids are distributed worldwide, especially in boreal and colder temperate climates. The center of diversity is the northern Pacific Ocean. Species occupy many types of aquatic habitats, including marine and fresh waters, and deep and shallow zones. A large number occur in near-shore marine habitat types, such as kelp forests and shallow reefs. They can be found in estuaries and in bodies of fresh water. Most cottids are small fish, under in length. The earliest fossil remains of cottids are otoliths potentially assignable to ...
