There are five main classes of vertebrates, but one of these classes is divided into three classes, giving a total of seven classes altogether.Mammals (Mammalia)Birds (Aves)Reptiles (Reptilia)Amphibians (Amphibia)Fish - which in turn are subdivided into:Agnatha (jawless fish without scales, e.g. lampreys and hagfish);Chondrichthyes (sharks and rays, which have skeletons of cartilage rather than bone)Osteichthyes (all the bony fish e.g. tuna, trout, whiting, etc.)
No fish. You can put them in one, but it is very cruel and inhumane.
The three classes of bony fish are Actinopterygii (ray-finned fish), Sarcopterygii (lobe-finned fish), and Dipnoi (lungfish). Ray-finned fish have fins supported by bony rays, lobe-finned fish have fleshy lobed fins, and lungfish are known for their ability to breathe air.
