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. They ...
This reduction in body temperature and metabolic rate allows the prolonged survival of animals capable of entering torpid states. In 2020, scientists reported evidence of the torpor in Lystrosaurus living ~250 Mya in Antarctica – the oldest evidence of a hibernation-like state in a vertebrate animal. [15] [16] [17]
Animal migration is the relatively long-distance movement of individual animals, usually on a seasonal basis. It is the most common form of migration in ecology. It is found in all major animal groups, including birds , mammals , fish , reptiles , amphibians, insects , and crustaceans .
During the first year, the squirrels began hibernation in late October. They started hibernating in mid August and early April respectively for the following two years, displaying a circannual rhythm with a period of about 10 months. [5] An annual rhythm has been observed in humans diagnosed with obsessive compulsive tic disorder (OCTD).

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.
Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [ 1 ]
Great Migrations is a seven-episode nature documentary television miniseries that airs on the National Geographic Channel, featuring the great migrations of animals around the globe. The seven-part show is the largest programming event in the ten-year history of the channel and is part of the largest cross-platform initiative since the founding ...
