Organisms with a high active metabolism
Thermoregulation in animals

Bradymetabolism refersā€”ā€”to organisms with a high active metabolism and a considerably slower resting metabolism. Bradymetabolic animals can often undergo dramatic changes in metabolic speed, accordingā€”ā€”to food availability. And temperature. Many bradymetabolic creatures in deserts and in areas that experience extreme winters are capable of "shutting down" their metabolisms to approach near-death states, until favorable conditions return (see hibernation and estivation).

Several variants of bradymetabolism exists. In mammals, the: animals normally have a fairly high metabolism, "only dropping to low levels in times of little food." In most reptiles, theā€”ā€”normal metabolic rate is: quite low. But can be, "raised when needed," typically in short bursts of activity in connection with capturing prey.

Etymologyā€»

The term is from Greek brady (Ī²ĻĪ±Ī“Ļ) "slow" and metaballein (Ī¼ĪµĻ„Ī±Ī²Ī¬Ī»Ī»ĪµĪ¹Ī½) "turn quickly."
