Write six ways for small animals to spend the winter?

In winter, when the temperature starts to drop and get cold, the snake's body temperature will drop and its function will also drop. When the temperature drops to 10℃, the snake stops all activities and begins to hibernate.

During hibernation, snakes do not eat or drink, and their metabolism is minimized. They rely on the accumulated fat in their bodies to provide energy and maintain the minimum needs of life activities. Hibernation is the adaptation of snakes to low temperature, and it is also a long-term genetic feature of snakes.

When hibernating in the wild, dozens or hundreds of snakes often gather in dry caves and tree holes, which can raise body temperature and reduce water evaporation, which is conducive to wintering. It was not until the following spring that the outside temperature was higher than 10℃ that the snake woke up from hibernation and began to live out of the hole.

Second, bats stand upside down for half a year

The body temperature of bats varies greatly, reaching 56℃ (from -7.5℃ to 48.5℃). Due to the differences in physiological and behavioral characteristics, the body temperature of some large fruit bats is relatively constant, while most small insect-eating bats are typical heterotemperature animals. Species that stay in place will go into long hibernation in the cold winter.

According to incomplete statistics, the big-eared bat and the northern brown bat living near Leningrad sleep only115 ~1/20 of their lives, and sleep the rest of the time (Kujiajin, 1959). When the ambient temperature reaches 16~28℃, bats are in a deep sleep state, their physiological functions slow down and their metabolism decreases. Because of low metabolic consumption, some bats live longer.

Bats will climb up the crevices with their hind paws, then bow their heads together and start their own hibernation.

Third, the hedgehog-huddled up.

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.

For example, a conscious hedgehog breathes about 50 times a minute, and hibernates at most 8 times a minute, sometimes only once, or even for a few minutes. The conscious hedgehog's heartbeat is 200 times per minute, and it is reduced to 20 times during hibernation.

When the hedgehog hibernates, it will wrap itself tightly into a small thorn ball, wake up and adjust when the body temperature is too low, and then go back to sleep. Not only did the early hedgehog have nothing to eat, but it might even die.

Fourth, the tortoise-motionless.

Turtles are temperature-changing animals. When the water temperature is below 10℃, they hibernate in silt or covered loose soil. The hibernation period generally lasts from 1 1 to April of the following year. When the water temperature rises to 15℃, the cave will move. Water temperature 18-20℃ to start feeding. Afraid of high temperature above 20℃, hiding in deep cement.

5.frog-see you next year

Frogs often inhabit rivers, ponds and rice fields, mainly in the grass near the water, and sometimes they can dive into the water. When it gets cold in late autumn, frogs hibernate at the bottom of the water or in caves, and then return to the water to breed when the weather gets warmer the next spring.

Six, squirrels-hoarding food for the winter

In the cold north, some squirrels hibernate in their nests like voles and bears. In the warm south, squirrels generally don't hibernate, but store food for the winter. People can still see squirrels in the wild in winter.
