  • poikilothermy, the ability of an organism to function over a wide internal temperature range
  • bradymetabolism, the ability to greatly alter metabolic rate in response to need; for example, animals that hibernate

"Cold blooded" and "Coldblooded" may also refer to:




  • A person or act said to be lacking in conscience
  • A horse bred for strength and calmness, such as a draft horse
