Hibernation lasts 3 months in the south, 4-6 months in the north, 7 months in Changbai Mountain Agkistrodon halys, and almost all snakes in South China do not hibernate. Snakes accumulate enough fat before hibernating and find underground burrows during hibernation. Snakes often hibernate in groups and can sleep together.
