Heterothermal

/ˌhɛtərəʊˈθɜːml/ adjective

Definition

Having or relating to different temperature conditions or the ability to tolerate varying environmental temperatures.

Etymology

From Greek 'hetero-' (different) and 'therme' (heat). A biological term used to describe organisms or systems with variable thermal properties.

Kelly Says

Unlike warm-blooded mammals that keep a constant temperature, some creatures like tuna fish are heterothermal—they heat specific muscles to stay warm while their bodies are cold, giving them superpowers in the ocean without the energy cost of full-body heating.
