Scientific name of cat

Scientific name of catfish

The scientific name of a catfish is a taxonomic name that provides a label, similar to a genus and species, for this taxon of fish. The taxonomic hierarchy of the scientific name of catfish is different from the hierarchy of the name of other fish (e.g. trout) which is species specific (i.e. scientific name), genus specific (e.g. Sarcocheilichthys), or family specific (e.g. family Salmonidae).

Biological classification

In the biological hierarchy of the scientific name of catfish, a fish is a subclass of the kingdom Animalia. A class is a division of a subclass. A phylum is a division of a class. A division is a division of a phylum. A class contains a taxon that is a member of this class. A subclass is a division of a class. A division is a division of a subclass. A taxon is the lowest rank in the hierarchy of taxonomic classification. A taxon can be any grouping of organisms, which is not necessarily a species or genus. A taxon can be a species, genus, order, family, etc. A taxon may have an accepted name, an accepted scientific name, an accepted binomial scientific name, an accepted epithet, or an accepted taxonomic authority. A taxon can be referred to by any of these names.

Fish are members of the phylum Chordata, which has four divisions: Cypriniformes, Gasterosteiformes, Sarcopterygii, and Tetrapoda.

The Chordata can be further divided into two taxa. Cypriniformes is the only division that contains an order containing a family. On the other hand, Gasterosteiformes is the only division containing a class. Gasterosteiformes contains two orders. One order is the order Sarcopterygii. Sarcopterygii contains two families. One of these two families, Tetrapodidae, contains two genera, including the monotypic genus Esox, which is a freshwater fish.

The taxon Esox has two species. Esox lucius is also a species, but it is a marine fish. It lives in North Atlantic waters and its geographical distribution is limited to the Gulf Stream. Esox lucius is not the only species with two names. There are other two species of Esox with two names, and which have different distributions.

Naso is a genus in the order Sarcopterygii. It has two species. The first species, Naso (Naso naso), is also a member of the family Sinipercidae, which also has two species, and one of which is the monotypic species Pteronazophylax, with a distribution limited to the North Atlantic, as its family's distribution is. The second species, Naso uruketo, is a member of the family Monoplacidae. Monoplacidae also contains two species, and one of them is the monotypic species Monoplax japonicus.

There are also marine and freshwater fish which belong to the orders of Sarcopterygii and Salmoniformes respectively, but not belonging to the two families and genera cited above. These fish are not members of the genus Esox.
