10 What is a hibernating animal?

? There are many hibernating animals, such as hedgehogs, snakes, bats, turtles, frogs, ants, snails, bears, toads, earthworms, crocodiles, squirrels, wasps, lizards, polar bears and so on. Let's talk about these animals.

1: Hedgehog: When the hedgehog hibernates in its nest, its body temperature drops to 6℃. In this case, the hedgehog is the animal with the lowest body temperature in the world, breathing 1- 10 times per minute. Litter is hedgehog's favorite hibernation place. When the temperature drops to 12℃, hedgehogs refuse to hibernate, and in order to drive away the cold, they still keep their body temperature by eating more. When the temperature drops to 7℃, the hedgehog goes into hibernation. Hedgehogs hibernate for four or five months. After hibernation, their body temperature drops and other physiological functions weaken.

2. Ants: Ants are temperature-changing insects and are extremely sensitive to low temperatures. Ants spend the winter in the underground part of their nests. When winter comes and the temperature is below 10℃, they nest underground and hibernate. During hibernation, ants don't eat, drink or move, and their metabolism drops, so they can survive the cold winter safely. Compared with the active state, the metabolism of dormant ants is not only slow, but also significantly different in quality. Ants consume fat when they are dormant. Ants in the natural environment have to resist the harsh environment and consume a lot of nutrients in the body. Not only not long, but also thin.

3. Snails: Snails retract their bodies into their shells, and use their own secretions to form a film to seal the mouth of the shells to protect their soft bodies from the cold. Safe winter can save your strength. Its mucus can provide it with nutrition.

Hibernation is a state in which the extreme but regular decline of body temperature, metabolism and other physiological activities is an adaptation to reducing energy consumption. Hibernating species can be roughly divided into active hibernating animals and passive hibernating animals. The latter, such as hamster, external factors, including photoperiod, food and external temperature, play a major role in the timing of this hibernation cycle event.
