Animals can be classified according to their mode of thermoregulation. Sort the animals below, indicating their likely thermoregulatory strategy. Note that poikilotherms are sometimes referred to as heterotherms.

Animals: Eagle Coyote Butterfly Salamander Walrus ArcticShrimp FreshwaterCatfish

Categories: Homeothermic endotherm, Homeothermic ectotherm, Poikilothermic ectotherm

Explanation: Eagles are endotherm and homoeothermic.

Coyote are endotherms and homoeothermic.

Walrus are Endothermic and homoeothermic.

The above organisms maintain constant internal body temperature irrespective of fluctuations in surrounding temperature.

Artic shrimp are ectotherms; and homoeothermic. Despite the fact that it has negligible source of intenal heat, its environmental temperature is relatively stable, therefore it is both ectotherms and homoeothermic.

Butterfly, freshwater catfish, Salamander are Poikilothermic. These organism's body temperature fluctuates with the immediate surrounding temperature. They lack internal body temperature.
