Pls at what degree can a frog survive the winter?

Frogs: When spring comes, amphibians such as frogs, lizards, snakes, and reptiles wake up from their long hibernation and crawl out of their burrows to start a new life.

It turns out that these animals are cold-blooded, and the body temperature of cold-blooded animals will be affected by the 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, in order to escape the cold, and wait until the ground temperature rises the next spring before coming out to move, which is why frogs hibernate.

Snakes: Hibernation is determined by the thermotropic characteristics of snakes. The metabolic activity of snakes is the result of the action of enzymes, which are the catalysts for chemical reactions in the body.

In general, enzymes require certain temperature conditions for their action. When this condition is satisfied, the catalytic effect of the enzyme can be played at its best, and the metabolism can be carried out most vigorously. Only then can the snake obtain sufficient energy, increase the activity and emergency of the body, and improve the ability to hunt prey and evade predators.

When the cold winter arrives, the snake dives underground. As the temperature decreases, the activity of enzymes in the snake also decreases, and the metabolism is extremely slow, so that it is unable to maintain normal activities and has to be in a state of hibernation. When snakes hibernate, they have the lowest energy consumption and the weakest life phenomena.

Because a snake is ectothermic, its body temperature can change depending on the environment.

Bears: Lack of food is the main cause of hibernation, and if food is sufficient, many bears do not hibernate and instead hunt all winter. But when there is not much food, the bear hides in the burrow for the winter.

Small mammals have a rapid drop in body temperature when they hibernat, but bears only have a body temperature of about 4 degrees, which slows their heart rate by 75%.Once a bear begins to hibernate, its energy** is converted from diet to stored fat in the body. Tom Evans, a field biologist in Alaska who works for the U.S. Fish and Wildlife Service's polar bear program, said the chemical changes were dramatic.

When fat is burned, the metabolism produces toxins. But when bears hibernate in hibernation, the cells break down these toxins into harmless substances and recycle them. This biochemical action also allows bears to ** water in their bodies so they don't urinate during hibernation, and polar bears can also take advantage of fat burning mechanisms.

This waking hibernation allows polar bears to remain active throughout the winter without hiding in their holes.

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.

As the temperature drops, it slowly enters a state of hibernation, during which they do not eat or drink, relying only on their own nutrients to maintain their vital signs and reduce their metabolism.

Frogs are good at camouflage:

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. The eyes of a frog are dull to see things that are still and sharp to things that are moving.

If the soil in the area where it is active is soft, in the autumn after the water has withdrawn, find a more secluded place to dig a hole deep enough to burrow without eating or drinking. If you can find a ready-made hole that is deep enough not to freeze in winter, it is also an ideal place for them to winter. When they hibernate, they slow their heartbeat, their metabolism becomes very slow, and they crouch there motionless, waiting for the next spring to bloom and the temperature rises.

One winter, I found flocks of frogs squatting there in several corners of a deep pit dug by hand
