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.
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] Fish account for more than half of vertebrate species. As of 2016, there are over 32,000 described species of bony fish, over 1,100 ...
A fish (pl.: fish or fishes) is an aquatic, anamniotic, gill-bearing vertebrate animal with swimming fins and a hard skull, but lacking limbs with digits.Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians.
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.
Sturgeon (from Old English styrġa ultimately from Proto-Indo-European *str̥(Hx)yón-[1]) is the common name for the 28 species of fish belonging to the family Acipenseridae. The earliest sturgeon fossils date to the Late Cretaceous , and are descended from other, earlier acipenseriform fish , which date back to the Early Jurassic period, some ...
The first respectable classification for some of the species in this superfamily appeared in Volume I of the tenth edition of Linnaeus's Systema Naturae in 1758 [note 4] which, based on John Ray's Synopsis methodica Animalium (1693), [77] included the genus Mormyrus within the order Branchiostegui. [78]
Depending on the species, anemonefish are overall yellow, orange, or a reddish or blackish color, and many show white bars or patches. The largest can reach a length of 17 cm (6 + 1 ⁄ 2 in), while the smallest barely achieve 7–8 cm (2 + 3 ⁄ 4 – 3 + 1 ⁄ 4 in).
The family currently includes 20 species across seven genera. [2] Several species are important food sources for humans, especially Brama brama in South Asia. The earlier form of the pomfret's name was "pamflet", a word which probably ultimately comes from Portuguese pampo, referring to various fish such as the blue butterfish (Stromateus ...
