What are the characteristics and functions of frog tongue

The frog's tongue is highly retractable and can roll up insects at a very fast speed to achieve the purpose of predation.

The root of the frog's tongue is at the front of the bottom of the mouth, but the tongue extends into the mouth. It is long and wide, with a forked front and a mucus-covered surface. When an insect flies, the frog jumps up, opens its mouth wide, quickly turns out its tongue, and sticks the insect into its mouth.

The body of a frog can be divided into three parts: head, trunk and limbs. The frog has four toes on its front feet, five toes on its back feet, and webbed feet. There are two slightly bulging small bags on both sides of the frog's head. That is its eardrum, through which the frog can hear sounds. The back of the frog is green, very smooth, very soft, and has patterns, and the abdomen is white. It can make it hide in the grass, making it easier to catch pests, and it can also protect itself. Its skin can also help it breathe. Its air sacs are only found in male frogs. Frogs use their tongues to hunt, and there is mucus on their tongues.
