Brumation
While endotherms and other heterotherms are described scientifically as hibernating, the way ectotherms such as lizards become dormant in cold conditions is very different, and a separate term was coined for it in the 1920s: brumation. It differs from hibernation in the metabolic processes involved: energy is stored in glycogen in addition to or in place of fats, and periodic water intake is required.
