In temperate and Northern latitudes, where temperatures fluctuations at times of the year significant, amphibians go into winter hibernation. In the autumn, when the temperature decreases, they groups gather at the wintering sites. Toads, frogs and newts hibernate on land, burrowing in moss, crawling into holes under the roots and stones.
Marsh frogs spend the winter in rapid freezing streams, at the bottom under the roots, in the midst of algae.
Before winter is very useful for her to fill his belly to fall fat, which in the cold will protect from the cold. Slowly fissioning, fat nourishes the body of the animal, not allowing him to die from exhaustion.
