Why do frogs hibernate and why do frogs hibernate

Frogs are amphibians, and amphibians are cold-blooded, and their body temperature 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, the frog burrows into the dirt, does not eat or move, and sleeps in a state to escape the cold, and waits until the ground temperature rises in the spring of the following year before coming out to move, which is why the frog hibernates. Therefore, hibernation is a survival method for animals to adapt to the cold external environment.

Scientists have conducted in-depth research on frog eyes and found that the retina of frog eyes is composed of three layers of cells: the photoreceptor cell layer, the intermediate contact cell layer, and the ganglion cell layer.

The photoreceptor cells in the first layer convert images of external objects into images on the retina and convert the images into electrical nerve signals. The second layer of contact cells is responsible for transmitting electrical signals to the third layer; The third layer of ganglion cells detects image features and codes these electrical signals to the brain. Ganglion cells are further divided into four categories, each of which performs a specific detection function and only responds to a certain feature of the moving target, identifying and extracting different features of the retinal image. In this way, a complex image is broken down into several easily recognizable features, improving the speed and accuracy of target discovery and identification.

Therefore, scientists call these four types of ganglion cells "detectors", which are "edge detectors", "convex edge detectors", "contrast detectors" and "dimming detectors". Taken together, the frog's eyes are particularly sensitive to both "fast-moving objects with rounded fronts" – insects that it likes to eat, and predators that are "fast-moving with large shadows". It does not respond to things that have no meaning to its existence, such as trees and blades of grass that do not move or shake.

The frog's eye can not only present images of the objects seen on the retina, but also analyze the images it sees, pick out specific image features, and then "communicate" to the brain through the optic nerve. After the "meticulous carving" of nature, this visual inspection system of frog eye has reached a very perfect point. The frog eye does not react to the background, but instead concentrates on moving relative to the background.

Moving, objects with specific morphological characteristics. As soon as the "shadow" of an insect or predator passes in front of its eyes, it is instantaneous.

Will react, pounce on food or flee into the water.

Frogs don't usually really hibernate, but they reduce their metabolic rate during the cold season to slow down their body's activity. This state is called "dormancy" rather than true hibernation.

During the winter months, food becomes scarce for frogs and water is not readily available. At this point, the frog slows down the body's metabolic rate to conserve energy and water. This allows them to survive for a longer period of time without food and water.

In addition, hibernation can help frogs cope with cold temperatures and prevent their bodies from being damaged by the cold.

Frogs hibernate to escape the cold. Frogs are amphibians, and their body temperature is affected by the temperature, and as the weather gets colder, their body temperature will slowly drop. When the temperature drops to a certain level, the frog hides in its burrow, does not eat or move, and sleeps to survive the winter.

Tips: Frogs are wild protected animals, and the protection of wild animals starts from themselves, refuses to buy and sell wild animal products, and does not interfere with the free life of wild animals. At present, the consumption of rare and endangered wild animals in society is not only a bad social habit, but also one of the reasons for the repeated prohibition of illegal hunting and killing of rare and endangered wild animals.

If there is no trade, there is no killing, and the consumption of wild animals is not eliminated, they do not belong on the table.

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 water source, in winter, the insects will also decrease a lot, and the frog's food ** will be reduced a lot, and they will choose to use hibernation to spend the winter safely 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 about 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 near 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, frogs hibernate under the water or in burrows, and return to the water to breed when the weather warms up the following spring.

Frogs are amphibians, and amphibians are cold-blooded. Body temperature is affected by the temperature, and as the temperature gets colder, the body temperature will gradually drop. When the temperature drops to a certain level, the frog burrows into the dirt, does not eat or move, and sleeps, using this plum chain to escape the cold, and waits for the source to travel until the next spring when the ground temperature rises before coming out to move.
