Homeothermic

Definition

An organism capable of maintaining a relatively constant body temperature, usually elevated above the ambient temperature.

Etymology

From Greek 'homo-', meaning 'same', and 'thermos', meaning 'heat'.

Example

Some species of insects exhibit limited homeothermy, allowing them to maintain a relatively stable body temperature.

Related Terms

• Temperature regulation
• Endothermy

Usage Notes

True homeothermy is rare in insects, as they are generally poikilothermic. However, some insects can regulate their body temperature to some extent.
