Detailed explanation-1: -All mammals and birds are capable of generating this internal heat and are classed as homoiotherms (ho-MOY-ah-therms), or warm-blooded animals. Normal temperatures for mammals range from 97° F to 104° F.

Detailed explanation-2: -endotherm, so-called warm-blooded animals; that is, those that maintain a constant body temperature independent of the environment. The endotherms primarily include the birds and mammals; however, some fish are also endothermic.

Detailed explanation-3: -Mammals and birds are the only true warm-blooded animals. They are called endotherms, meaning they produce their body heat internally. warm-blooded animals have body temperatures that usually stay the same.

Detailed explanation-4: -It’s one of the most basic biology facts we’re taught in school growing up: Birds and mammals are warm-blooded, while reptiles, amphibians and fish are cold-blooded.

Detailed explanation-5: -Basically, warm-blooded animals include birds and mammals. There are many birds and mammals in the world, but not nearly as many as there are insects, fish, reptiles, and amphibians.
