Cold-blooded organisms maintain their body temperatures in ways different from mammals and birds. The term is now archaic in scientific contexts. Cold-blooded creatures were, initially, presumed to be incapable of maintaining their body temperatures at all. They were presumed to be "slaves" to their environments. Whatever the environmental temperature was, so too was their body temperature.

Since that time, advances in the study of how creatures maintain their internal temperatures (deemed: thermophysiology), have shown that many of the earlier notions of what warm-blooded and cold-blooded mean, were far from accurate (see below: breaking down cold-bloodedness). Today scientists realize that body temperature types are not a simple matter of black and white. Most creatures fit more in line with a graded spectrum from one extreme (cold-blooded) to another (warm-blooded).
