How do frogs burrow into the ground to hibernate?

Frogs are cold-blooded animals, and the body temperature of cold-blooded animals is 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, and in order to survive, cold-blooded animals such as frogs burrow into the dirt and are in a state of suspended animation, as a way to escape the cold, and wait until the ground temperature rises the following spring before coming out to move.

In one case, the frog spits out a layer of mucus, or bubble-like liquid, wraps itself up, and hides it in the dirt or in a hidden place to sleep ......Spring wakes up.

Frogs are amphibians.

Its lungs are not very well respirated, so its breathing characteristics are:

Tadpoles breathe with their gills, and some species of tadpoles breathe with strong gills that grow outside the body, and adult frogs not only breathe through the lungs (taking swallowing breathing - the lungs are not well evolved), but also through the stomata on the surface and capillaries. Breathe.

Frogs hibernate in soil burrows, under fallen leaves, in soft mud at the bottom of rivers, and in tree cavities. Hibernation begins in mid to late October when the temperature drops to 10 degrees Celsius, and when the temperature rises in March of the following year, the trees have new leaves and the hibernation ends.

In spring, frogs lay eggs on aquatic plants, and the eggs slowly turn into tadpoles. Tadpoles are black, round with a round body and a long tail, the tadpole grows day by day, first growing hind legs, then front legs, the tail gradually shortens and degenerates, and finally becomes a frog.

The frog is an expert at catching pests, the frog catches pests all by his long and wide tongue, the root of the tongue grows in front of the mouth, the tip of the tongue is backward, and it is also forked, there is a lot of mucus on it, as long as the small flying insects fly by, they jump up suddenly, open their big mouths, quickly stretch out their long tongues, and eat the pests at once.

Most will hibernate in sun-dried leaf-covered soil, under stones, rotten wood, or in the mud at the bottom of the pool.

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.

Frogs are cold-blooded animals, and when their body temperature is too low, they will freeze to death, and in order to survive, they have to be in a state of suspended animation, which is hibernation. In the earthen cave, hibernation begins in the middle and late October when the temperature drops to 10 degrees Celsius, and in March of the following year, the temperature rises, and the trees grow new leaves, and the hibernation ends.

When animals hibernate, they don't starve to death if they don't eat for the winter. Because before hibernation, they have already begun to prepare for hibernation to survive this difficult period. The preparation of these animals before hibernation is very special, that is, from the beginning of the summer, they gradually accumulate nutrients in their own bodies, which are enough to meet the basic metabolic consumption of the body throughout the hibernation process.

Despite the accumulation of a large amount of nutrients in the body, how can the hibernation period last for several months? It turns out that during the hibernation period, the animal lies in the nest and does not eat or move, or rarely moves, the number of breaths decreases, the body temperature also drops, the blood circulation slows down, the metabolism is very weak, and the nutrients consumed are relatively reduced, so the nutrients stored in the body are enough. When the body's stored nutrients are almost depleted, the hibernation period will be over.

After hibernation, the body of the animal appears very thin, and after waking up, it has to swallow a lot of food to replenish nutrients, and it is volatile to return to normal body as soon as possible.

In a hole under the roots of a tree near the water or in a hole in the soil.

When the frog hibernates, it hides in a hole under the roots of a tree near the water or in a hole in the soil, and does not eat or drink, and basically does not move.

Not in the water anyway. Haha, in the hole, in the hole.

Frogs are amphibians, cold-blooded, and their body temperature is affected by the temperature. As the temperature gets colder, so does the frog's body temperature. When the temperature drops to a certain level, the frog burrows into the dirt, does not eat or move, and sleeps, which is called "hibernation", as a way to escape the cold and wait for the spring flowers to bloom before coming out to move.

It is a survival method for animals to adapt to the cold.

First of all, because the frog's living environment is in the pond near the source of the water source, in winter, the insects will also be reduced a lot, and the frog's food ** will be reduced a lot, and they will choose to use hibernation to safely spend the winter and consume less energy.

Finally, there is another reason that because ** is also a very important respiratory organ of frogs, frogs cannot be kept warm by regulating their body temperature like other animals, and can only choose to hibernate.

The larvae of frogs are called tadpoles, and their evolution is generally divided into the following three stages:

Clause. 1. Hatch from the eggs and become tadpoles;

Clause. Second, the limbs will gradually grow, and the tail will gradually disappear;

Clause. 3. It takes about three months to completely transform into a young frog.

First of all, frogs are oviparous animals, and they usually lay their eggs in advance and then wait for the fertilized eggs to hatch on their own. The hatchling frog larvae are tadpoles, black all over and with a small tail.

Secondly, tadpoles will initially rely on the nutrients in the egg cells to live, and as the tadpole grows up, it will gradually grow limbs, and the tail will gradually degenerate and disappear over time.

Finally, the process of transforming from a tadpole to a frog lasts for three months, and finally the tadpole will completely metamorphose into a young frog.

Baby frogs will choose to hibernate in ponds, tree holes or mud holes to spend the winter, because frogs are cold-blooded animals, and if the temperature is too low in winter, there is a possibility of freezing to death, so they need to spend the cold weather in a place where they can keep warm, and then come out to play after the temperature warms up.

Frogs generally live close to water sources, and generally frogs lay eggs and fertilize in the water, and after the eggs hatch, they become tadpoles, live in the water, and then become young frogs to land and move. However, the egg-laying method of the tree frog is different, and the eggs produced by the spot-legged tree frog are like a white soap foam, and like a ball of cream, sticking to aquatic plants.

Tadpoles generally feed on plant foods such as diatom and green algae, and when mature, they will eat insects as their staple food, as well as some snails, snails, shrimps, and fish. In late autumn, when the weather gets colder, the frogs hibernate under the water or in their burrows, and return to the water to breed when the weather warms up the following spring.

Frogs hibernate in soil burrows, under fallen leaves, in soft mud at the bottom of rivers, and in tree cavities. Hibernation begins in mid-to-late October when the temperature drops to 10 degrees Celsius, and in March of the following year, when the temperature rises, the trees have new leaves, and hibernation ends.

In spring, frogs lay eggs on aquatic plants, and the eggs slowly turn into tadpoles. Tadpoles are black, round with a round body and a long tail, tadpoles grow day by day, first growing the legs of the Houxiao orange, then the front legs, the tail gradually shortens and degenerates, and finally becomes a frog.

The frog is an expert at catching pests, the frog catches pests all by his long and wide tongue, the root of the tongue grows in front of the mouth, the tip of the tongue is backward, and it is also forked, and there is a lot of mucus on it, as long as the small flying insects fly by, they jump up violently, open their big mouths, quickly stretch out their long tongues, and eat the pests at once.
