Poikilothermynoun

(biology) The quality of having a body temperature that varies or fluctuates, depending on the temperature of the environment; cold-bloodedness.

Thermoregulationnoun

(biology) The maintenance of a constant internal temperature of an organism independent of the temperature of the environment

Thermoregulation

Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
