Hibernation and Dormancy in Animals

The video explains how animals adapt to winter through hibernation, dormancy, and brumation. Hibernation involves deep sleep and reliance on fat reserves, seen in animals like hedgehogs and bats. Dormancy, observed in bears and squirrels, allows periodic waking to eat stored food. Brumation, a state of torpor in reptiles and insects, involves low metabolism and body temperature. The video highlights the differences between these states and the survival strategies animals use during cold months.

Why do some animals enter a state of hibernation?
