poikilotherm

poikilotherm (exotherm) Organism that regulates its body temperature by behavioural means, e.g. by basking or burrowing. Such animals are often termed ‘coldblooded’, although when active their body temperature is little different from that of homoiothermic (‘warm-blooded’) animals. Poikilothermy is characteristic of lower vertebrates (fish, amphibians, and reptiles), but not of birds and mammals.
