Cold-blooded is an informal term for one or more of a group of characteristics that determine an animal's
thermophysiology. These include:
*
Ectothermy
An ectotherm (), more commonly referred to as a "cold-blooded animal", is an animal in which internal physiological sources of heat, such as blood, are of relatively small or of quite negligible importance in controlling body temperature.Daven ...
, controlling body temperature through external processes, such as by basking in the sun
*
Poikilothermy
A poikilotherm () is an animal (Greek ''poikilos'' – 'various', 'spotted', and ''therme'' – 'heat') whose internal temperature varies considerably. Poikilotherms have to survive and adapt to environmental stress. One of the most important s ...
, the ability of an organism to function over a wide internal temperature range
*
Bradymetabolism
Bradymetabolism refers to organisms with a high active metabolism and a considerably slower resting metabolism.Bligh, J., and Johnson, K.G., 1973. Glossary for terms for thermal physiology. ''Journal of Applied Physiology'' 35(6):941–961. Bradym ...
, the ability to greatly alter metabolic rate in response to need; for example, animals that hibernate
