Gk. homos, same or similar + therme, heat] An organism, such as a bird or mammal, capable of maintaining a stable body temperature independent of the environment.
Animal that maintains a near-constant internal body temperature, regardless of whether it is endothermic or ectothermic.
an organism that maintains a constant internal body temperature
organism whose internal body temperature is maintained at a relatively constant temperature through the organism's metabolic activities; its body temperature typically does not change in response to changes in environmental temperature fluctuations; homeotherms were once called "warm-blooded"
(home´ ee o therm) [Gr. homos: same + therme: heat] • An animal which maintains a constant body temperature by virtue of its own heating and cooling mechanisms. (Contrast with heterotherm, poikilotherm.)
An animal which maintains a constant body temperature by virtue of its own heating and cooling mechanisms (mammals, birds).
An organism which maintains an approximately constant body temperature, usually above that of the surrounding medium.
