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]
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.

The phylogenetic classification of bony fishes is a phylogenetic classification of bony fishes and is based on phylogenies inferred using molecular and genomic data for nearly 2000 fishes. [ 1 ] [ 2 ] [ 3 ] The first version was published in 2013 and resolved 66 orders. [ 2 ]
Fish species (IUCN, 2016-2) 15,219 extant species have been evaluated; 12,028 of those are fully assessed [a] 9679 are not threatened at present [b] 2343 to 5534 are threatened [c] 71 to 158 are extinct or extinct in the wild: 65 extinct (EX) species [d] 6 extinct in the wild (EW) 87 possibly extinct [CR(PE)] 0 possibly extinct in the wild [CR ...
A table row is included in this example to demonstrate the result; note that both the header template and each row have to have "no-ecology" set or else the table will be malformed. {{ Species table | genus = Acinonyx | authority-name = [[ Joshua Brookes | Brookes ]] | authority-year = 1828 | species-count = one | no-note = y | no-ecology = yes }}
A whole set of terms including taxonomy, systematic biology, systematics, scientific classification, biological classification, and phylogenetics have at times had overlapping meanings – sometimes the same, sometimes slightly different, but always related and intersecting. [1] [11] The broadest meaning of "taxonomy" is used here.
