What is the largest frog in the world?

The largest frog in the world is the African giant frog. It is the largest frog in the world and can be called the "giant" among frogs. The length from mouth to buttocks reaches 33 cm, and the diameter of the eyes can reach 2.5 cm, which can be called the "big eyes" among frogs.

The mouth is wide and can swallow relatively large food. There are small teeth on the upper jaw to prevent food from slipping out of the mouth.

The skin on the back is granular and warty, with a greenish-brown color, and the adult frogs are well camouflaged when basking on wet moss-covered rocks.

The root of its tongue grows in the front part of the lower jaw, while the tip of the tongue is facing inside the mouth. The tongue can be turned out of the mouth and stretched out very long, thus expanding its feeding range.

How do frogs spend the winter?

Frogs usually hibernate in water, caves, or mud during the winter, and enter a state of suspended animation, or hibernation. Frogs are cold-blooded animals, and will freeze to death if the temperature is too low. Frogs hibernate in the winter, and will come out again when the temperature warms up in the spring of the following year.

Frogs are amphibians belonging to the phylum Chordata, class Amphibia, order Anura, and family Ranidae. They breathe with gills, but after mutation, adults mainly breathe with lungs and also through the skin.

Frogs often live in rivers, ponds, and rice fields. They mainly move in the grass near the water, and sometimes lurk in the water. They are mostly active at night and feed mainly on insects.

Frog meat is tender, low in fat and sugar, and contains protein, carbohydrates, calcium, phosphorus, iron, vitamin A, vitamin B, vitamin C and various hormones.

When and where frogs hibernate

Frogs usually hibernate in water or caves when the weather turns cold in late autumn. Frogs are amphibians, and their body temperature is affected by the air temperature. When the temperature drops to a certain level, frogs hibernate in water or caves, and return to the water to reproduce when the weather warms up in the spring of the following year.

The reason why frogs hibernate is that they cannot regulate their body temperature. When the weather is cold, the body temperature is too low and the frog's movements become slow. In addition, insects cannot survive in winter and frogs cannot obtain sufficient food sources.

Hibernation is also called "winter hibernation". The life activities of some animals are extremely reduced in winter. It is an adaptation of animals to adverse environmental conditions in winter, such as lack of food and cold. Bats, hedgehogs, polar squirrels, etc. all have the habit of hibernation.

The body temperature of some heterothermic and poikilothermic animals can drop to close to the ambient temperature during cold winters, and their whole bodies become paralyzed. When the ambient temperature drops further or rises to a certain level or under other stimuli, their body temperature can quickly return to normal levels.
