Idiothermic is a technical term that refers to an animal's ability to regulate its body temperature internally, without relying on the external environment. Synonyms for idiothermic include endothermic, homeothermic, and warm-blooded. Endothermic creatures produce their own body heat through metabolic processes, while homeothermic animals maintain a consistent internal body temperature regardless of the external conditions. Other terms that can be used as synonyms for idiothermic include thermoregulatory, self-heating, and autogenic temperature control. Knowing these synonyms can help you better understand scientific articles and discussions related to animal physiology and behavior.
