Warm-blooded

Warm-blooded animals retain thermal homeostasis; that is, they keep their core body temperature at a nearly constant level despite of the temperature of the surrounding environment. This can engage not only the ability to generate heat, but also the ability to cool down.

Warm-blooded animals manage their body temperature by regulating their metabolic rates. Both the terms "warm-blooded" and "cold-blooded" have fallen out of support with scientists, because of the generality of the terms, and due to an increased understanding in this field. Body temperature types do not drop into simple either/or categories. Each term may be replaced with one or more variants. Body temperature maintenance incorporates a wide range of different techniques that result in a body temperature continuum, with the traditional ideals of warm-blooded and cold-blooded being at opposite ends of the spectrum.
