Discover the difference between hibernation, aestivation, torpor and denning, and learn which animals do them, when, why and how.
Hibernation may last days, weeks, or months—depending on the species, ambient temperature, time of year, and the individual's body-condition. Before entering hibernation, animals need to store enough energy to last through the duration of their dormant period, possibly as long as an entire winter.
hibernation, a state of greatly reduced metabolic activity and lowered body temperature adopted by certain mammals as an adaptation to adverse winter conditions. A brief treatment of hibernation follows. For full treatment, see dormancy. The term hibernation is commonly applied to all types of winter dormancy in vertebrate animals. Thus defined, hibernators include many fishes, amphibians, and ...
Hibernation is a state where animals significantly reduce their metabolic rate, body temperature, heart rate and breathing to conserve energy during periods when food is scarce. Unlike sleep, which is primarily a mental change, hibernation involves drastic physiological changes, and waking a hibernating animal can be fatal due to the high energy cost of rewarming. Hibernation is triggered by ...
Similarly, hibernation is a type of dormancy, but not all dormant animals hibernate. That’s because hibernation is a really specific kind of dormancy. Dormancy describes an animal that has slowed down its bodily functions for a little while, but hibernation has some very specific rules. There are lots of different kinds of dormancy...
What is hibernation, how does it work, and which animals do it?
Hibernation is a specialized biological state allowing certain animals to survive periods of environmental hardship. It involves a profound reduction in metabolic activity and is far more intricate than simply sleeping through a challenging season. This strategy enables animals to endure harsh conditions, such as extreme cold or scarcity of food, by conserving energy over extended durations ...
