Detailed explanation-1: -warm-bloodedness, also called Homoiothermy, also spelled Homeothermy, in animals, the ability to maintain a relatively constant internal temperature (about 37° C [99° F] for mammals, about 40° C [104° F] for birds), regardless of the environmental temperature.

Detailed explanation-2: -To use their proper terms, warm-blooded animals are known as endotherms, and cold-blooded creatures are called ectotherms.

Detailed explanation-3: -Endothermic animals are those that must generate their own heat to maintain an optimal body temperature. In ordinary language, these animals are commonly referred to as “warm-blooded.” The term endotherm comes from the Greek endon, meaning within, and thermos, which means heat.

Detailed explanation-4: -ectotherm, any so-called cold-blooded animal-that is, any animal whose regulation of body temperature depends on external sources, such as sunlight or a heated rock surface. The ectotherms include the fishes, amphibians, reptiles, and invertebrates.

Detailed explanation-5: -Warm-blooded body systems are also known as endotherms, since they internally regulate temperature. Cold-blooded animals, also be known as ectotherms, rely on the environment around them to regulate their body temperatures.
