what group or class are fish in ?

Question

Are they mamals like whales or what are most of them.

Answer 1

Well they are all animals, but instead of being in class mammalia, they are in class Pisces (Actinopterygii). This class contains all true fish, others like skates rays and sharks, the cartilagenous fishes go into class Chondrichthyes. Mammals are characteristic of being warm blooded, furred, mostly terrestrial animals with mammory glands that are used to provide milk to offspring. Fish are cold blooded, they have scales, all are aquatic, several are semiaquatic (lungfish, mudskippers), they all lay eggs (with the exception of some), they have gills instead of lungs, and lack mammory glands....there are other things too, but this gives you the idea.

Here is the taxonomic heirarchy for a largemouth bass, every thing up to class is similar to all "fish"

Kingdom Animalia --animals
Phylum Chordata -- chordates
Subphylum Vertebrata --vertebrates
Superclass Osteichthyes -- bony fishes
Class Actinopterygii --ray-finned fishes,spiny rayedfish
Subclass Neopterygii -- neopterygians
Infraclass Teleostei
Superorder Acanthopterygii
Order Perciformes -- perch-like fishes
Suborder Percoidei
Family Centrarchidae --sunfishes
Genus Micropterus Lacepède, 1802 -- black basses, largemouth basses
Species Micropterus salmoides

(Lacepède, 1802) -- largemouth bass

I hope this answers your question!

The fish are further classified into three classes. These classes are the Agnatha, jawless fish such as the hagfish and lampreys; the Chrondrichthyes, fish whose skeleton is made of cartilage such as sharks, rays and skates; and the Osteichthyes, fish whose skeleton is composed mostly of bone such as bass, perch, catfish, and flounder. There are approximately 50 species of jawless fish, 600 species of cartilaginous fish and more than 30,000 species of bony fish. The bony fish, Osteichthyes, are then further classified into two main groups called the ray-finned group (e.g., perch, and catfish) and the lobe-finned group (e.g., lungfish). Most bony fish belong to the “ray-finned” group. There are approximately 70 fish orders known to biologists. because of these distinct characteristics all vertebrate fishes arent kept in the same class.....
