What parts does a snail's body consist of?

The snail's body consists of shell, head, tentacles, eyes, mouth, abdomen and tail.

The snail has a spiral shell on the outside of its body. Inside the shell is a membrane that wraps around its soft body. The soft body of a snail is divided into three parts: the head, the ventral foot, and the visceral mass. The head has retractable tentacles. The front pair is shorter and can feel the soil and food, which has a sense of touch. The back pair is longer. The eyes at the top can distinguish between light and darkness and have a sense of smell. The snail's mouth is on the ventral side of the head. The ventral foot is wide and muscular, and is the snail's locomotion organ.

When a snail crawls, a small round hole appears on the edge of the mantle on the right side of the shell opening. This is the opening through which the snail exchanges gases with the outside world and is called a respiratory pore.

There is a small hole in the middle of the snail's tentacles, which is its mouth. Inside is a serrated tongue called the radula. The surface of the radula is like a file, with some small keratinous teeth neatly arranged. Snails are the animals with the most teeth in the world. There are tens of thousands of teeth on their tongues, which give them good chewing ability.

Snail's life habits

1. It likes dark, moist and secluded environment, hides during the day and comes out at night, and is very sensitive to strong light stimulation.

2. They like to burrow into loose humus soil to live, lay eggs, regulate body humidity and absorb some nutrients, which can last for 12 hours.

3. It likes humidity and is afraid of waterlogging. On a humid night, feeding the snail with wet food can increase its appetite, but waterlogging can suffocate the snail.

4. Self-eating survival ability. As soon as the snails are hatched, they will crawl and feed without the need for maternal care. When invaded by enemies, the head and feet will retract into the shell and secrete mucus to seal the shell opening. When the shell is damaged, it will secrete certain substances to repair the flesh and shell.

5. Have strong tolerance to cold, heat, hunger and drought.

6. The temperature is kept constant between 25 and 28 degrees Celsius, which ensures vigorous growth, development and reproduction.

Which part of the snail is the most sensitive?

The entire body of a snail includes the shell, head, neck, outer shell membrane, foot, internal organs, sac and other parts. It has a spiral shell on its back. Its shapes and sizes vary, including pagoda-shaped, gyroscope-shaped, cone-shaped, spherical, and pipe-shaped.

The tentacles are the most sensitive part of the snail. If you touch the tentacles of a snail, it will think it is dangerous, so it will hide in its shell. If the snail's shell is slightly cracked, it will repair it with its secretions, but if the shell is completely lost, the snail will die in a short time.

1. The snail's tentacles are organs used to sense the external environment. The snail's tentacles are like a blind man's walking stick, which is used to touch the road. When the snail is walking, if it touches an obstacle with its tentacles, it will immediately change the direction of its advance.

2. The snail has eyes at the top of its tentacles, so some people compare its tentacles to the flashlights people use when walking at night.

3. In addition to these uses, the snail's tentacles also act as a nose and can smell odors.
