The movement of a dead frog is a biological discharge. It was discovered by the Italian biologist Professor Galvani, which shows that the organism itself is also electrified, and the most typical is the electric eel discharge phenomenon. In fact, the discovery of the Dead Frog movement, like Fleming's invention of penicillin, shows that success is reserved for those who are observant and knowledgeable.

Frogs move differently from other animals, and most of them use jumping to move, because their body structure is the result of adapting to jumping. Leaving aside the question of evolution, we will divide this topic into three parts: body shape, bones, and muscles to understand the movement of frogs.
Generally speaking, frogs are slender and streamlined, and their limbs are mostly webbed between their fingers, which are the characteristics of frogs adapted to swimming. In terms of limbs, the forelimbs are shorter than the hind limbs, and the slender hind limbs are usually folded up, and when they want to move, they stretch out and bounce out, so the shape and principle of the frog legs are similar to springs. And the function of the forelimbs, like the shock absorbers of the car, is to cushion the impact of landing after jumping.
However, there are still some frogs that are not good at swimming and jumping, such as the broad toad, which has webbed hind limbs but is not good at swimming. However, the bulky appearance and the inflexible structure of the limbs make it impossible for the toad to jump far if it wants to (hence the development of a special defensive structure - the toad).
In addition, the way frog limbs connect with the body is more primitive, the knee and hand joints are on the outside of the body, and the body cannot be lifted off the ground, and is always spread on the ground. Therefore, when crawling, it appears clumsy, so jumping is the best way for frogs to exercise.

The vocal organs of frogs are the vocal cords. Located above the laryngeal hilar cartilage. Some male frogs also have external vocal sacs that can bulge and vibrate on both sides of the mouth, and the vocal sacs resonate, so that the frog's song is majestic and loud After the rain, when you walk to the pond, you will hear the male frogs' calls echoing each other, one after another, and merging into a chorus. >>>More
