Question 1: What are the parts of a snail’s body? The main components of a snail's body: shell, feet, mouth, eyespots, and two pairs of antennae

Question 2: Where is the snail? Snails generally live in relatively humid places, such as hiding from the sun among plants. sun. Snails hibernate in cold areas, and snails living in the tropics also hibernate during the dry season. They hibernate when the temperature is below 15°C and above 33°C. Only come out when the temperature and humidity are right. Snails generally like to live in dark, humid, loose and humus-rich environments. They live day and night, are most afraid of direct sunlight, and are sensitive to the environment. All in all, snails will appear at night or early in the morning when the ecological environment is good, humid, with green vegetation, and the temperature is higher than 15°C and lower than 33°C.

Question 3: How many parts is a snail made of? The entire body of a snail includes eyes, mouth, feet, shell, antennae and other parts, with a spiral body on its back. Shells vary in shape, color, and size. Their shells are pagoda-shaped, gyro-shaped, conical, spherical, pipe-shaped, etc. The white jade snails, capped snails, loose snails, bright snails, brown cloud agate snails, etc. that are currently farmed in China all have their own unique appearance. The snail's eyes are located on the back of its head.

Question 4: What are the parts of a snail’s body? The entire body of a snail includes shells, heads, necks, shell membranes, feet, internal organs, sacs and other parts. It carries a spiral shell with various shapes. ***, different sizes, including pagoda-shaped, gyro-shaped, conical, spherical, pipe-shaped, etc. The snail's eyes are on the antennae (there are two small black dots), which are called visual antennae. Amazingly, experiments have proven that snail eyes have the ability to regenerate. That is, after the snail's eyes are removed, small black dots appear on the top of the optic antennae about three days later; small white meat balls grow after eleven days.

Question 5: Where do snails often appear? In the grass or flowers after the rain.

Question 6: Which part of the snail uses to eat food? Snail teeth - an amazing number

Snails are the animals with the most teeth in the world. Although its mouth is about the size of a pinhead, it has 25,600 teeth!

There is a small hole a little lower in the middle of the snail's small antennae. This is its mouth. There is a serrated tongue inside, which scientists call the "radula". The surface of the radula is like a rasp used for grinding ginger powder, with some small horny teeth arranged neatly. When the snail eats, it uses this "small rasp" to grind the leaves of the plant, and then eats them bit by bit. Although its teeth are small and cannot be seen with the naked eye, they are very powerful. Even if you put the snail in a cardboard box that is harder than its body, it can bite through the cardboard and crawl out. Snails have a variety of food habits and have many hosts. In addition to damaging green leafy vegetables, they also damage many types of vegetables and crops such as Brassicaceae, Solanaceae, Leguminosae, and Cucurbitaceae. Both seedlings and adult plants can be harmed. When the snails are young, they only feed on the mesophylls and leave the epidermis; larger individuals use their radula to scrape the leaves and stems of plants, lick and grind them into small holes or even break off the stems, or the leaves may have irregular nicks, or the veins may remain, which is serious. When the damage is caused, it can cause a lack of seedlings

Question 7: The functions of each part of the snail's body are the tentacles and abdominal legs

The head of the snail has two pairs of tentacles, one of which is a large pair. The tips of the tentacles have eyes. The mouth is on the ventral surface of the head; the feet are very fat and the ventral surface is flat, making it suitable for crawling. The visceral sac is hidden inside the shell and contains the snail's internal organs.

The two pairs of tentacles of a snail are very special. When the head and feet are stretched out and crawling on the ground, the two pairs of tentacles always stretch out and move slowly. Just because it usually shrinks its body into its shell and has horn-like tentacles on its head when crawling, people call it a snail.

The snail’s antennae are organs used to sense the external environment. Some people say that a snail's tentacles are like a blind man's crutch, used to touch the road. When a snail is walking, if it touches an obstacle with its antennae, it will immediately change its direction. However, just using this metaphor to explain the function of snail's tentacles is not complete, because there are eyes growing on the top of snail's tentacles. So some people compare its tentacles to the flashlights people use when walking at night.

Snails have very poor eyesight. It can see farther under weak light, but it can't see far under strong light. Someone once did an experiment and proved that a certain snail can see 6 centimeters away under weak light, but can only see 4 to 5 millimeters under strong light, which is only equivalent to about 1/12 of the vision under weak light.

In addition to these uses, the snail's antennae also serve as a nose, allowing it to smell. If a snail's antennae were cut off, the poor little creature would be unable to smell anything and therefore would be unable to find food. It seems that the snail's tentacles are really important to its life.

The snail’s mouth is located on the ventral surface of its head, which is perfect for crawling and looking for food. There are two pairs of touching lips on the two sides of the mouth. The touching lips are very sensitive and function just like human lips. Inside the mouth are jaws and radula, which are essential organs for snails to eat. There is only one jaw, which is used for chewing food.

The radula is a long chitinous band, much like the tongue of higher animals, but there are many rows of neatly arranged small teeth growing on this band, which is the same structure as the radula of chitons, abalone, and field snails. The front end of the radula can be extended from the mouth to scrape food and, like the grater we use, can grind the food. Snails mostly eat the roots, stems and leaves of plants, so they are harmful to crops.

There is a neck at the back of the snail's head, which is approximately semi-cylindrical when extended. The back of the neck is connected to the internal organs.

The ventral surface of the neck is the foot, which is composed of muscle fibers and stretches backward into a tongue shape when crawling. There is a gland in the center of the front end of the abdomen of the foot, called the foot gland, which can secrete mucus to keep the foot constantly moist to avoid damage when crawling. When a snail crawls over, there is always a clear trace left on walls, trees or stems and leaves. We can often follow this trace to find the snail. This mark is caused by the mucus secreted by the foot glands. If you put the captured snail in a glass tank and observe its activities from the bottom or side of the tank, you can see that its abdomen and legs are constantly contracting in waves and moving forward slowly.

When it crawls, a small circular hole is exposed on the right side of the shell mouth. This small hole can continuously open and close, called the breathing hole or valve, which is the opening used by the snail to breathe.
