Do snails have eyes, do snails have eyes?

Snails are animals with eyes. The eyes are located on the head at the front of the body, but there are two locations - the base of the antennae and the antennae. Usually 1 pair of tentacle snails, such as mountain snails, bean snails, etc., have eyes located at the base of the antennae; The eyes of snails with 2 pairs of antennae, such as the common African giant snail and Svenhaus's giant snail, are located on the large antennae.

With the naked eye, the snail's eyes are just two small black dots, which feel a little shiny and transparent. In fact, the eyes of a snail are similar to that of humans, and are composed of corneas, lenses, retinas, and nerves, but the structure is very simple, so they can only sense changes in light and shadow, and cannot really see objects like human eyes.

To put it bluntly, snails don't have good eyesight. But for snails, the eyes are not the most important, because most snails are nocturnal. In the dark of night, especially at the bottom of dense forests, most of the fingers are missing, so the snails do not need to use their eyes to see the road or find food.

However, the light-sensitive eye can remind the snail to go home and rest at dawn, or let the snail accidentally come out during the day to hide, and these places are usually more humid and suitable for snails to inhabit.

Although the eyes are not very important to the snail, the snail is still a very precious structure. You can look at the tentacles of the snail by touching your fingers, and the frightened snail always immediately retracts its eyes into the antennae. If the snail's antennae happen to be a little transparent, you can see the snail's eyes moving inside the antennae, and the snail often retracts its eyes under the base of the antennae and inside the top of the head!

It wasn't until the snail felt that the danger was out of the way that it stuck its eyes out for a long time.

Yes, snails have two pairs of antennae, the long pair has eyes at the tip, and the short pair has a nose.

Snails have eyes! Its eyes grow on its antennae!

The snail tentacles in the cartoon have two round eyes on them.

Yes Yes When he crawls, there are 2 long things, each with a small dot at the top, and that is his eye pull, friend.

Such a hilarious question, of course.

The eyes of the snail grow at the tip of the tentacles of the plum. When the snail's body is fully relaxed, it has a pair of antennae on the top of its head, and there are two small black dots at the top of the antennae, which are its eyes. Its eyes don't have much effect, and can only feel the light and shade changes of the outside world

The morphology of snails varies greatly, and the shells are generally conical or spherical in shape. Left or right hand. The body spiral layer is large and expanded. The shell surface is smooth, often with dark brown bands. The head has 2 pairs of antennae, and the eyes are located at the tip of the last 1 pair of antennae. Hermaphroditism.

Growing environment

Snails like to live in a dark and damp, loose and humic environment, day and night, most afraid of direct sunlight, sensitive to the environment, most suitable for the environment: temperature 16 30 (23 30 times, the fastest growth and development); Air humidity 60% 90%; The humidity of the feeding soil is about 40%; The pH is 5 7. When the temperature is below 15 and above 33, it is dormant, and when it is lower than 5 or higher than 40, it may freeze to death or heat death.

But the various snail snails are different.

Snails like to burrow into loose humus soil to inhabit, lay eggs, regulate the humidity in their bodies and absorb some nutrients, which can last up to 12 hours. Omnivorous and partial feeding coexist. Likes humidity and is afraid of flooding.

Snails, molluscs of the phylum Gastropods, are the most common mollusks on land and have high edible and medicinal value.

The snail has a carapace, shaped like a small snail, with a variety of colors, and its head has four antennae, and when it walks, its head sticks out, and when it is frightened, its head and tail are retracted into the carapace together, feeding on plants, and laying eggs in the soil or on trees.

It prefers to live in a dark and damp, loose and humus environment, is nocturnal, most afraid of direct sunlight, sensitive to environmental reactions, and is widely distributed all over the world. Snails not only hibernate in summer, but also in winter.

Range of distribution of snails.

There are 40,000 species of snails all over the world, and snails are distributed in all provinces and regions of China, living in forests, shrubs, orchards, vegetable gardens, farmlands, parks, gardens, temples, mountains, flatlands, hills and other dark and damp areas.

It feeds mainly on plant stems, leaves, flowers, fruits and roots. It is one of the agricultural pests and an intermediate host for some parasites of livestock and poultry. <>
