Cold blooded animals are referred to as
Poikilothermic
Homothermic
Polythermic
Homeostatic
Correct answer is A
Insects, fish, reptiles, and amphibians are cold blooded because their body temperature changes along with the external temperature which are known as poikilothermic, while birds and mammals are warm blooded because they maintain a high body temperature regardless of the external temperature.
A poikilothermic is an animal whose internal temperature varies considerably. It is the opposite of a homoeothermic, an animal which maintains thermal homeostasis.
