What is the function of a snail s shell and eyes?

The role of a snail's eyes is simply to perceive ambient light. The head of a snail has two pairs of antennae, one of which has eyes at the tip of a large antennae.

The snail's eye has poor vision and is unable to distinguish colors due to the absence of an optic cone in the eye. Use your fingers to approach the eye quickly, but don't touch it. By looking at whether it reacts to this, you can see if the snail's eyes can see or not.

The shell of the snail mainly plays a protective role. The snail lives in the shell, and the main vital organs of the snail (heart, lungs, etc.) are in the shell. The shell of a snail also protects against the cold.

In winter, the snail will close the mouth of the shell and make it as thick as possible to keep it warm. If the snail shell is damaged and repaired poorly, the snail will most likely die.

Extended Materials. The tentacles of a snail.

The head of a snail has two pairs of antennae. The antennae of a snail are organs used to sense the external environment. Normally, the antennae shrink into the shell, and the snail will extend its antennae when crawling. The tentacles of the snail also function as a nose and can smell scents.

Snail teeth.

Snails are the animals with the most teeth, but their teeth are not "three-dimensional teeth". Despite having tens of thousands of teeth, they are unable to chew food. This is because they crush food with a toothed tongue – a ribbon-like structure covered with teeth – so that it can be digested.

The snail's shell contains vital organs such as its heart and lungs, which can also be retracted when it is dry and then sealed.

Needless to say, the eyes are certainly seeing.

<>1. Protective effect: The main function of the snail shell is to protect the soft body and internal organs. The shell is like a house where a snail lives permanently, not only to shelter from the wind and rain, but also to hide from enemies.

2. Body moisturization: snails generally live in relatively humid places and avoid direct sunlight in the plants. They only appear after rain in arid places and are almost not seen on sunny days.

When the air is too dry and hot, they will go dormant, and when dormant, they can secrete mucus, forming a dry membrane to close the shell opening, hiding the whole body in the shell, and when the temperature and humidity are right, they will come out to move.

3. Help respiration.

The mantle cavity of the snail will create 1 opening at the mouth of the shell, called the "breathing hole", which is where the gas enters and exits. When the snail is retracted into the shell, the opening of the breathing hole is left at the mouth of the shell for breathing.

The snail shell is mainly used to protect the internal organs and body of the snail, and its shell is the "house" where the snail lives for a long time, which can not only play a role in sheltering from the wind and rain, but also better resist predators, and can also avoid excessive loss of water in the snail's body. The shell of the snail is a very important feature and structure, and it is also a basis for judging the species of the snail, just like its signboard, the shell of each snail looks different, and there will be certain differences in size, shape and color, so the species of the snail can be distinguished by the shell of the snail.

The snail shell is an important feature and structure of the snail, and it is also an important classification basis for the snail. Just like the snail's sign, each snail's shell grows differently and comes in different sizes, shapes, structures and colors, which can be used to distinguish the species of snails.

I believe that many people have seen a snail, it moves very slowly, and it carries a very hard shell, so what is the function of the snail shell? It is mainly used to protect the internal organs and body of the snail, and its shell is the house where the snail lives for a long time, which can not only play a role in sheltering from the wind and rain, but also better resist the enemy, and can also avoid excessive loss of water in the snail's body.

The role of snail shells can be ground to make fertilizer.
