Some animals can literally survive winter by freezing. For example, some fish , amphibians , and reptiles can naturally freeze and then "wake" up in the spring. These species have evolved freeze tolerance mechanism such as antifreeze proteins .

Winter rest (from the German term Winterruhe) is a state of reduced activity of plants and warm-blooded animals living in extratropical regions of the world during the more hostile environmental conditions of winter. In this state, they save energy during cold weather while they have limited access to food sources.
For a better understanding, “cold-blooded actually means the animal’s body temperature is basically the same as its surroundings. A fish swimming in 40° F water will have a body temperature ...

Sleeping the season away. If an animal’s physiology, diet, or other characteristics don’t allow it to stay warm and/or find sufficient food during the winter, an additional set of survival ...
Total length varies typically from about 42 to 72 cm (17 to 28 in) and body mass averages about 2 kg (4 + 1 ⁄ 2 lb) in spring in the smaller species and 8 kg (18 lb) in autumn, at times exceeding 11 kg (24 lb), in the larger species. [4] [5] [6] The largest and smallest species are not clearly known.
Animals failing to reach these fat levels usually do not survive the winter. During their hibernation, their metabolism decreases by 25%. In areas such as Primorsky Krai and their introduced range, common raccoon dogs hibernate only during severe snowstorms. In December, their physical activity decreases once snow depth reaches 15–20 cm (5.9 ...
