Mammals and birds are the two classes of animals that are endothermic. The term 'endothermic' is the biological term for an animal that is warm-blooded.
Mammals and birds are endothermic.
what two classes of vertebrates use external fertilisation
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.
I don't fully understand the question, but from what I gather the two types are birds and mammals. Sorry if this isn't correct. Endothermic means self-regulating body heat by the way.
The vertebrates are further divided into five groups or classes.
Mammals and birds are endothermic vertebrates. They are able to regulate their own body temperature. The term 'endothermic' is the biological term for an animal that is warm-blooded. Therefore, some of the thousands of endothermic vertebrates could be dogs, cats, kangaroos, parrots, eagles, monkeys, cheetahs, horses, koalas, ducks, etc.
There are 5 types of vertebrates: Fish, amphibian, reptile, bird and mammal. Endothermic (warm blooded) vertebrates are: birds, mammals. Exothermic (cold blooded) vertebrates: fish, amphibian, reptile.

Fishes, amphibians and reptiles are ectothermic while mammals and birds are endothermic.
Fish, amphibians, reptiles, birds and mammals. Fish are ecothermic, aquatic vertebrates. Amphibians and reptiles are ectothermic vertebrates. Birds and mammals are endothermic vertebrates.
Yes. A skunk is an endothermic vertebrate, able to maintain its own body temperature. It is a mammal, and mammals and birds are endothermic vertebrates. The term 'endothermic' is the biological term for an animal that is warm-blooded. Vertebrate means it has a backbone.
