Animals hibernate and don't eat. Why aren't they hungry?

Because every autumn, hibernating animals eat a lot. Enough fat is stored in the body as energy to provide for body consumption during hibernation. At the same time, hibernating animals do not exercise, reduce the number of breaths and reduce the energy needs to maintain a minimum life, so they will not be hungry if they do not eat. So what are the animals that need hibernation? Let's have a look!

What are the hibernating animals?

Squirrels, snakes, frogs, toads, Asian black bears, lizards, earthworms, polar bears, snails, crocodiles, hedgehogs, turtles, bats, wasps, dormice and so on all need to hibernate.

Hibernation is a state in which an extreme but regulated decline in body temperature, metabolism, and other physiological activities is adapted to reduce energy consumption.

This definition no longer includes the seasonal or diurnal dormancy of variable temperature organisms when they react passively to a drop in ambient temperature. Therefore, real hibernation is limited to birds and mammals.

Hibernating species can be divided into two categories: active hibernating animals and passive hibernating animals, the latter such as hamsters, external factors, including photoperiod, food and external temperature play a major role in the timing of hibernating cycle events.
