homeotherm
Internally heated animal
A homeotherm is an animal that maintains a stable internal body temperature regardless of external conditions—what's commonly called warm-blooded.
Mammals and birds are homeotherms, generating heat through metabolism rather than absorbing it from their surroundings.
The term contrasts with poikilotherm (cold-blooded animals whose temperature fluctuates with their environment).
Also spelled homoiotherm.
