Body Temperature Control Control of body temperature is important for maintaining homeostasis, particularly in areas where temperature varies widely with time of day and with season.
- An ectotherm is an animal whose regulation of body temperature depends mostly on its relationship to sources of heat outside its body. Most reptiles, invertebrates, fishes, and amphibians are ectothermic.
- An endotherm is an animal whose body temperature is regulated, at least in part, using heat generated by its body. Birds and mammals are endothermic.
