Are koalas ectotherms or endotherms

Answer 1

Koalas are endothermic because they are mammals. The more common term for endothermic is 'warm blooded' and all mammals are warm blooded.

Answer 2

The term endotherm refers to animals (birds, mammals, some fishes and insects, and even some plants) that are capable of generating sufficient amounts of heat energy to maintain a high core temperature (e.g. 37-40 °C in birds and mammals) by metabolic means -- usually derived from aerobic activity of locomotor muscles in animals and by unique biochemical mechanisms in plants (e.g., skunk cabbage). Endotherms differ from an ectotherm because they typically have core temperatures above that of the surrounding environment, whereas the core temperatures of ectotherms depend on external sources of heat -- primarily from solar radiation.

Answer 3

Koalas are endothermic because they are mammals. The more common term for endothermic is 'warm blooded' and all mammals are warm blooded.
