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.)

How many classes of vertebrates are there?
5
What classes of vertebrates are ectotherms?
Ectothermic vertebrates include all classes of fish, amphibians, and reptiles. They rely on external sources of heat to maintain their body temperature. This is in contrast to endothermic vertebrates, such as birds and mammals, which can regulate their body temperature internally.
In respiration where do the five classes of vertebrates get each reactant from and how do they absorb it into their lungs?
Glucose is taken from food.Oxygen is taken through air
Classes are included in the group Tetrapoda?
Yes, Tetrapoda is a group that includes classes such as Mammalia, Reptilia, Amphibia, and Aves. Tetrapoda refers to all vertebrates with four limbs or descendents of four-limbed ancestors.
How many phenotypic classes may be generated from a three-point testcross?
There are eight possible phenotypic classes that can be generated from a three-point testcross: two parental classes and six recombinant classes.
