Which critters sleep in the winter and wake up in the spring

1. Hedgehog. Hedgehogs are isotherms because they can't regulate their body temperature stably to keep it at the same level, so hedgehogs hibernate in winter.

2. Frogs. In late autumn, when the weather gets colder, frogs hibernate under the water or in burrows, and return to the water to breed when the weather warms up the following spring.

3. Dormouse. Dormouse, named because of its hibernation habits. There are about twenty species of dormice, which are found in Africa, Europe, and Asia, and are good at climbing trees. They come out after dark and feed on fruits and nuts.

4. Brown bears. Brown bears hibernate and their body temperature, heartbeat and detoxification system stop during hibernation to reduce the loss of heat and calcium, as well as hypothermia and osteoporosis.

5. Bats. Bats generally have the habit of hibernating, and most of the places of hibernation are in holes, and the ability to metabolize is reduced during hibernation, breathing and heartbeat are only a few times per minute, blood flow slows down, and body temperature is lowered to the same level as the ambient temperature.

The first way is to hibernate. For example, snakes, frogs, turtles, etc., they hide in their holes in winter and sleep until spring, and for such a long time, they do not eat, drink, or move, and slowly consume body fat to survive the cold winter.

Bears are also sleeping, but they will wake up at the slightest noise, and when they are hungry, they will come out to find something to eat, which is called false hibernation or semi-hibernation.

The second way is to move the place of residence. For example, geese, swallows, etc., .They fly to the warmer south to spend the winter before winter arrives. On the one hand, it is because it is warm, and on the other hand, it is good for them to survive.

The third method is to thicken the fur or feathers on the body. For example, rabbits, deer, foxes, sparrows, crows, etc. Their fur or feathers are much thicker in winter than in summer.

As for what to eat, they don't have to worry, that is, they try to eat as much as possible in summer and autumn, and eat fat. In winter, they eat when they can find food, they can't find anything to eat, and they are not afraid to be hungry for a few days.

The fourth way is to store food. For example, squirrels, bees, ants, etc. In the autumn they store a lot of food in their homes, and in the winter they don't have to go out.

The fifth method is to let the eggs overwinter. For example, praying mantises, locusts, etc. In autumn they lay their eggs, which they spend the winter on branches, in the grass, and in the dirt.

The eggs are protected by a special egg pouch and are not afraid of the cold, and when spring comes, their larvae will crawl out and play happily everywhere.

1. Spring is coming, and the small animals that wake up from hibernation include snakes, frogs, lizards, turtles and other animals.

2. Hibernation is also called "winter sting". The extreme reduction in the vital activity of some animals in winter is an adaptation of these animals to the adverse external environmental conditions in winter. Bears, bats, hedgehogs, polar squirrels, frogs, snakes, etc., all have hibernation habits.

There are three types of hibernation, the first is the hibernation of amphibians and reptiles such as snakes and frogs, whose body temperature is in harmony with the surrounding environment, and if the ambient temperature drops, the body temperature will drop and enter a state of hibernation, which cannot be adjusted. The second type is squirrels and other animals whose body temperature is usually kept at a constant temperature, and when hibernating, their body temperature can be lowered to a temperature close to the surrounding environment, but in order to avoid freezing of body fluids below 0, their body temperature is maintained between 5. The third type is bears, whose body temperature only drops by a few degrees when hibernating, but can sleep without eating for a long time, which should be close to sleep and hibernation under strict classification.

3. To sum up, the hibernating animals of the class of mammals include polar squirrels, chinchillas, European dormice, golden hamsters of the order of rodents, bears of the carnivorous order, bats of the order Pterodactyl, hedgehogs of the order Hedgehogs, non-mammalian hibernating animals such as amphibian frogs and reptiles snakes and turtles, and species such as scorpions in the phylum of arthropods cannot be found in winter.

Spring is coming, and there are many small animals that wake up at the east gate, such as snakes and frogs, because these animals have to sleep in winter and wake up in spring.

1. Reptiles. Such as snakes, lizards, turtles and other animals.

2. Amphibians. Such as frogs.

3. Fish. 4. Molluscular animals. Such as snails, shellfish, etc.

5. And a considerable number of perennial insects also have hibernation habits.

6. Some small mammals also have hibernation habits. Such as rodents, bats, badgers, martens, spiny moles, etc.

7. Large mammals like bears wake up.

There are many small animals that wake up from hibernation, and the most annoying of them is flies.

Small animals such as black bears and frogs wake up from hibernation.

Spring is coming, and all the small animals in Domin are awake, snakes, turtles, frogs and other animals.
