What animals sleep in summer?

African lungfish is the most famous summer sleeping creature. When there is enough rain, it can breathe happily with its cheeks. In the dry season, when the swamp dries up, African lungfish will get into the mud to sleep. Due to the hot weather, the mud pile outside has already dried up and become a mud hole invisibly. African lungfish opens a "small skylight" with its mouth, and then oozes a mucus from the skin, which hardens the wall of the mud hole. It goes through this hole and breathes fresh air with its lungs. It can sleep in a mud hole for several months without eating or drinking, and then it will come back to life in the water when the rainy season comes.

2, porcupine

There is a mammal porcupine that eats earthworms in Margash Island, Africa. In hot summer, the ground is very hot, and earthworms can't live in shallow layers, which makes it difficult for porcupines to get food. Due to the temporary break of the food chain, porcupines have to go into a long summer sleep. Don't wake up until autumn comes.

3. Misgurnus anguillicaudatus in the waters along the Danube River

Misgurnus anguillicaudatus, who lives in the waters along the Danube, will sleep in the mud when the river dries up in summer. It only relies on its special intestine to breathe air to maintain its life.

4.snails

Snails are animals that sleep in winter and summer. Whenever the dry and hot season comes, it hides in its shell and sleeps in summer. When late autumn comes, it begins to move again, often climbing into crevices, caves or underground seclusion, and then hibernating again. Every time a snail sleeps, it secretes a kind of mucus, which seals the mouth of the shell to resist the heat outside or the freezing cold in the ice and snow.

5. Black viper

The black viper mainly exists in Shedao, Lushun Nature Reserve, Dalian, at the southern end of Liaodong Peninsula stratum. They hibernate like other snakes, but they sleep when snakes are most active in summer, because they can't find food not only in winter, but also in summer. There is only one animal in this snake island, the viper. Other animals gradually disappeared after the island became an island due to crustal movement thousands of years ago, leaving only this kind of reptile with strong endurance. In order to survive, they can eat nothing for a long time and only prey on birds when migratory birds pass by in spring and autumn, so they can only hibernate and sleep in summer and winter.

Extended data

Summer sleep, like hibernation, is a natural phenomenon for animals to survive in the season of food shortage. Xia Mian is also called Xia Zhe. In summer, the life activities of animals are extremely reduced, which is an adaptation of some animals to the hot and dry season. For example, ground tigers (insects), African lungfish, sand lizards, grassland turtles and ground squirrels all have the habit of sleeping in summer.

squirrel

Whenever the summer heat comes, chipmunks and striped squirrels in some areas lie curled up in their "bedrooms" paved with leaves, sleeping soundly. At that time, their bodies were as cold as death. After a while, the summer heat faded and the weather turned cold, and these little guys started to move as usual.
