Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
This species is nocturnal, with a diet of insects, other small animals, fruits and flowers. [12] The fat-tailed lemur is the only known primate to hibernate for extended periods of time, up to seven months. It performs this torpor during the dry season to minimise the impacts of droughts. During the wet season, it gorges on food, accumulating a ...
Hibernation is voluntary, whereas torpor is involuntary, like breathing. There are many animals that do go into full hibernation. True hibernators include squirrels , mice, bats, and turtles .
Black bear mother and cubs hibernating, utilizing a hibernaculum as a maternity den. Like other animals, mammals hibernate during seasons of harsh environmental conditions and resource scarcity. As it requires less energy to maintain homeostasis and survive when an individual is hibernating, this is a cost-effective strategy to increase ...

[9] [10] In the traditional definition of hibernation, the largest marmots are considered the largest "true hibernators" (since larger "hibernators" such as bears do not have the same physiological characteristics as obligate hibernating animals such as assorted rodents, bats and insectivores).
