The average length of an Arctic ground squirrel is approximately 39 cm (15 in). Since Arctic ground squirrels undergo drastic seasonal changes in body mass, it is difficult to give an average mass; [7] adult females are close to 750 g (26 oz), while males may weigh nearly 100 g (3.5 oz) heavier.

Hibernating Arctic ground squirrels may exhibit abdominal temperatures as low as −2.9 °C (26.8 °F), maintaining sub-zero abdominal temperatures for more than three weeks at a time, although the temperatures at the head and neck remain at 0 °C (32 °F) or above.
Thirteen-lined ground squirrels can survive in hibernation for over six months without food or water and special physiological adaptations allow them to do so. [6] They alternate between torpor bouts of 7 to 10 days when their body temperatures drops to 5-7°C, and interbout arousals of less than 24 hours with their body temperature back to 37 ...
Grey squirrels, or Eastern grey squirrels, primarily live in the Eastern half of the U.S. and southern Canada. There is also a healthy population in the U.K., where they were imported in the 19th ...
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 .
However, when animals live in an environment that is inhospitable for much of the year, then hibernation is not necessary. One of the few animals that does so are lemmings, which have a mass migration after they come out of dormancy. However, most animals living in the arctic would still be active, even during the most brutal times of winter.
