5 days ago · cold-bloodedness, the state of having a variable body temperature that is usually only slightly higher than the environmental temperature. This state distinguishes fishes, amphibians, reptiles, and invertebrate animals from warm-blooded, or homoiothermic, animals (birds and mammals).
An ectotherm (from the Greek ἐκτός (ektós) "outside" and θερμός (thermós) "heat"), more commonly referred to as a "cold-blooded animal", is an animal in which internal physiological sources of heat are of relatively small or of quite negligible importance in controlling body temperature.

Key points. Most animals need to maintain their core body temperature within a relatively narrow range. Endotherms use internally generated heat to maintain body temperature. Their body temperature tends to stay steady regardless of environment.
