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]
Common names of fish can refer to a single species; to an entire group of species, such as a genus or family; or to multiple unrelated species or groups.Ambiguous common names are accompanied by their possible meanings.
This is a list of fish with common names that are based on the names of other animals. The names listed here may refer to single species, broader taxa ( genera , families ), or assortments of types. Where names are ambiguous, the various meanings should be listed here.
The vast majority of extant fish are members of Osteichthyes, being an extremely diverse and abundant group consisting of 45 orders, over 435 families and 28,000 species. [3] It is the largest class of vertebrates in existence today, encompassing most aquatic vertebrates, as well as all semi-aquatic and terrestrial vertebrates.
This is a list of fish families sorted alphabetically by scientific name. There are 525 families in the list.

The halfmoon (Medialuna californiensis), also known as the blue perch, is a species of marine ray-finned fish, a sea chub from the subfamily Scorpidinae, part of the family Kyphosidae. It is native to the coasts of the eastern Pacific Ocean off western North America. It is fished for using hook and line and it is a desirable food fish.
Although widespread as a group, the individual species are often restricted to a single river or river basin. [4] [5] They are found in a wide range of habitats, including rivers, streams, pools and lakes; some species are rheophilic. [4] [5] The vast majority of pike cichlids are predatory and feed on fish, insects, and other small animals ...
