Catalog of Fishes is a comprehensive on-line database and reference work on the scientific names of fish species and genera. It is global in its scope and is hosted by the California Academy of Sciences. It has been compiled and is continuously updated by the curator emeritus of the CAS fish collection, William N. Eschmeyer.
Fishes are a paraphyletic group and for this reason, the class Pisces seen in older reference works is no longer used in formal taxonomy.Traditional classification divides fish into three extant classes (Agnatha, Chondrichthyes, and Osteichthyes), and with extinct forms sometimes classified within those groups, sometimes as their own classes: [1]
Fishes of the World is a standard reference for the systematics of fishes.It was first written in 1976 by the American ichthyologist Joseph S. Nelson (1937–2011). Now in its fifth edition (2016), the work is a comprehensive overview of the diversity and classification of the 30,000-plus fish species known to science.
The sauger (Sander canadensis) is a freshwater perciform fish of the family Percidae that resembles its close relative, the walleye. The species is a member of the largest vertebrate order, the Perciformes. [3] It is the most migratory percid species in North America. [4]
The European pilchard (Sardina pilchardus) is a species of ray-finned fish in the monotypic genus Sardina. The young of the species are among the many fish that are sometimes called sardines. [3] [4] This common species is found in the northeast Atlantic, the Mediterranean, and the Black Sea at depths of 10–100 m (33–328 ft). [1]
The fish's overall color is a brassy silver with occasional blue/green iridescence, [8] making it one of the dullest-colored member of its genus. [ 12 ] The largest recorded Jolthead porgy was 76 cm, [ 13 ] while they commonly grow up to 54 cm. [ 14 ] Though they normally grow to around 8 lb, [ 7 ] The heaviest weighed 23.36 lb. [ 15 ]
Cookeolus japonicus is a species of fish in the family Priacanthidae, the bigeyes and catalufas. It is the only extant species of Cookeolus, [1] except for C. spinolacrymatus, an extinct Late Pliocene fish known from a fossil specimen collected in Okinawa, Japan. [2] C. japonicus is found throughout the tropical and subtropical oceans, except ...
The football fish family and genus names are derived from a combination of himantos, which means a "leather strap", "thong" or "leash", with lophus, meaning "crest" or "tuft". Reinhardt did not explain this name but it is thought to refer to the thick, leathery illicium of the type species , H. groenlandicus .
