LEARN MORE ************** To learn more about this topic, start your googling with these keywords: - Thermoregulation: the strategy through which the body maintains its internal temperature. - Endotherm: an animal that generates most of its heat internally. - Ectotherm: an animal that relies on environmental heat sources. - Mesotherm: an animal with an intermediate heat generating strategy. - Poikilotherm: an animal whose internal temperature varies considerably. - Heterotherm: an animal that sometimes keeps its body temperature the same and sometimes lets it vary. - Homeotherm: an animal whose internal temperature does not change much.
