Homeotherm: A homeotherm is a warm-blooded animal (such as homo sapiens). Another term for us warm-blooded creatures is endotherm.

Those of us who are homeotherms or endotherms are as opposed to a poikilotherm (an organism such as a frog that is cold-blooded) and a stenotherm (a creature that can only survive only within a very narrow temperature range).

Homeotherm is all Greek. The "homeo-" comes from the Greek "homo" meaning "the same" + "-therm" comes from the Greek "therme" meaning "heat" = the same heat.
