Adult frogs can t live without water, so how do they hibernate when the river freezes?

They will hide under the water or in wet places such as caves.

Will go into hibernation early, or in a humid place.

Find a good habitat in advance by sensing in advance.

They will perceive in advance and find a suitable place for their hibernation.

They will find a good place in advance in case they need it.

They go to wet places to take root before winter sets in.

They hibernate in wetter places.

Before the river freezes, find a place to the east.

Because they will feel the temperature change, find another nest in advance.

Find a place that suits the east side early.

Frogs generally lie dormant underwater, burrows, and mud for the winter, and will also enter a state of suspended animation, which is commonly known as hibernation. Because frogs are cold-blooded, they will freeze to death if the temperature is too low, and they hibernate in the winter, and can resume their activities when the temperature warms up the following spring.

Frogs often inhabit rivers, ponds, and rice paddies, and are mainly found in the grass near the water, but sometimes they can also lurk in the water. Most of them are active at night, eating insects as their staple food, and also eating some snails, snails, small shrimp, small fish, etc.

Frogs are cold-blooded animals that hibernate underwater or in burrows when winter comes, and come out to breed when the weather warms up the following spring.

Normally, they hibernate in winter, so they don't do anything about it, just let us fall asleep.

Baby frogs survive the winter by hibernation in dark places.

Frogs spend their winters in hibernation.

They will hibernate.

Frogs (frogs) belong to the phylum Chordates, amphibians, anceridae, and amphibians of the frog family, adults without tails, eggs laid in water, fertilized in vitro, hatched into tadpoles, respiration with gills, after mutation, adults mainly use lung breathing, and also use ** breathing.

Frogs survive the winter by hibernation because frogs are amphibians that have a smooth surface of their body and are devoid of hairs and feathers. It is an ectothermic animal with a very poor body temperature regulation, which changes with the temperature and if it does not hibernate, it will freeze to death. When hibernating, it lowers its metabolism and tries to live with the nutrients it already has, without eating or drinking.

Wake up again in the spring.

Hibernation, the body temperature of cold-blooded animals will be affected by the air temperature, and as the temperature gets colder, their body temperature will gradually decrease. When the temperature drops to a certain level, some animals will freeze to death, in order to survive, cold-blooded animals such as frogs burrow into the dirt, in a state of suspended animation, in order to escape the cold, and wait until the next spring when the ground temperature rises before coming out to move, which is why frogs hibernate.

In late autumn, when the weather gets colder, frogs hibernate at the bottom of the water or in burrows, and come out to breed when the temperature rises the following spring. In general, when frogs hibernate, their body's metabolism slows down, and they squat in their burrows motionless, so that they do not consume energy and can survive without eating or drinking. <

1. When the weather gets cold in late autumn, frogs will hibernate at the bottom of the water or in their burrows, and then come out to breed when the temperature rises in the following spring. In general, when frogs hibernate, their body's metabolism slows down, and they squat in their burrows motionless, so that they do not consume energy and can survive without eating or drinking.

2. The frog is a cold-blooded ectothermic animal, and when the ambient temperature drops below 10, the frog's body temperature will also drop. The drop in their body temperature causes their metabolism to slow down, so that they stop eating, their activity decreases, and they do not even eat or exercise, lurking in burrows and under the water, which is the hibernation phenomenon of frogs.

3. At the same time, not only cold-blooded animals such as frogs should hibernate in winter, but also some warm-blooded animals should hibernate in winter. However, the hibernation of these animals is different from that of frogs, and they will burrow into warmer places to spend the winter, and they will not eat or drink, and wait for the temperature to rise. Frogs, on the other hand, burrow into burrows and underwater, and come out in the spring when the temperature rises.

Baby frogs go into hibernation for the winter.

The frog is an animal that hibernates in winter, so it does not move at all during the winter, as if it is asleep, and before winter comes, it burrows itself in the soil by the pond.

Because frogs are cold-blooded animals, the temperature is too low will freeze to death, as the temperature drops, it will slowly enter a state of hibernation, they will not eat or drink water during hibernation, only rely on their own nutrients to maintain vital signs, and reduce their metabolism.

Introduction to frogs

Frogs belong to the amphibians of the phylum Chordates, amphibians, tailless, frogs, adults without tails, eggs laid in water, fertilization in vitro, hatching into tadpoles, respiration with gills, after mutation, adults mainly use lungs to breathe, and also use ** breathing. The upper jaw has teeth, usually vomer teeth.

shoulder girdle fixed thoracic type, vertebral body uneven type, recommended vertebral transverse process columnar; There is no intermediated cartilage between the two bone nodes at the end of the toes. The tympanic membrane is distinctly hidden under the skin,** smooth or with wart grains. The tongue is generally oblong, and the posterior end is mostly notched.

Frogs are slimmer and are more good swimmers. The neck is inconspicuous and has no ribs. The ulna of the forelimbs heals with the radius, and the tibia of the hind limbs heals with the fibula, so the claws cannot rotate flexibly, but the limbs are muscular.

There are two main groups of animals: frogs and toads. But there is no strict distinction between the two groups of animals.

Generally speaking, toads mostly live on land, so they are rough; Frogs are slimmer and more good at swimming.

Hibernation It turns out that these animals are cold-blooded animals, and the body temperature of cold-blooded animals will be affected by the air temperature, and as the temperature gets colder, their body temperature will gradually drop. When the temperature drops to a certain level, some animals will freeze to death, in order to survive, cold-blooded animals such as frogs burrow into the dirt, in a state of suspended animation, in order to escape the cold, and wait until the next spring when the ground temperature rises before coming out to move, which is why frogs hibernate.

During the winter, it is dormant and relies on the fat stored in the body to maintain its vital characteristics.

Hibernation is a type of animal.

Dormancy is an adaptation to the deterioration of conditions such as temperature, humidity or food. By lowering the level of metabolism, the animal enters a state of paralysis and resumes its activities when the environmental conditions improve. Due to the imperfect regulation mechanism of heat production and heat dissipation, the body temperature changes with the change of environmental temperature, and is usually suitable for living at a temperature of 10 20, and when the temperature drops to 7 8, it enters a dormant state, which is called hibernation.

Frogs (e.g., black spotted frogs) hibernate in tree roots, rocks, burrows, or soil layers, while others (e.g., giant toads, Chinese forest frogs) sink into the mud at the bottom of rivers and lakes.

Frogs hibernate in the soil of rivers, lakes, pond banks or rice paddies. When the temperature drops below 10, the frog chooses a place to hibern, squats on the softer ground, sways its hind limbs from side to side, and sits little by little in the soil. Finally, a frog hole is formed around the frog, the walls of which are very smooth.

If the frog is taken out, the soil hole is like a sand mold for a sand casting.

To understand how frogs sit in the soil when they hibernate, do a small experiment. In winter, take a wooden box or large flower pot and fill it with damp and soft soil. Then place the preserved black spotted frog on the soil surface, buckle the bell or large beaker, and place it in the room of 7 8.

The frog will begin to sit on its legs and sit in the soil, passing left and right, and the frog will be buried in the soil.
