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] |
Zoarcoidei
Zoarcoidei is a suborder of marine ray-finned fishes belonging to the Order (biology), order Perciformes. The suborder includes the wolffishes, Pholidae, gunnels and eelpouts. The suborder includes about 400 species. These fishes are predominantly found in the North Sea (other), boreal seas of the Northern Hemisphere but they have colonised the Southern Hemisphere. Many members of this suborder are Extremophile, extremophiles adapted to deepwater ecosystems (including Hydrothermal vent, hydrothermal vents) and polar waters. Taxonomy Zoarcoidei was first proposed as a taxonomic grouping by the American zoologist Theodore Gill in 1893 as the Superfamily (biology), superfamily Zoarceoidea. The 5th edition of ''Fishes of the World'' classifies the Zoarcoidei as a suborder within the order Scorpaeniformes. Other authorities classify this taxon as the infraorder Zoarcales within the suborder Cottoidei of the Perciformes because removing the Scorpaeniformes from the Perciformes ...
