0 a homeothermic animal (= one able to keep its body temperature at the same level despite changes in the temperature around it):
A newborn infant is a homeotherm, but over a long period of time, cannot maintain the thermal processes.
I'd like to celebrate being a warm-blooded homeotherm by visiting the Hall of Mammals at the Museum of Natural History.
Big crocodiles are homeotherms which can keep a stable body temperature once warm.
