Can snails see with their eyes?

Although the eyes of garden snails can’t focus or see colour, they would just about be able to make out this other snail moving past, or a predator approaching. The snail’s ability to discern different intensities of light helps it navigate towards dark places.

How do snails see?

A: Yes, snails can see. For most North American land snails, the eyes are located at the ends of the two upper (longer) tentacles. In a few species, the eyes are located at the bases of these tentacles. The snails’ eyes are fairly advanced, with lenses that can focus, similar to the lenses in our eyes.

Is it possible for a snail to have eyes?

Snails are strange-looking creatures with shells and large stalks sticking out of the tops of their heads. Because most snails are small, it can be difficult to see their primary features. However, snails do have eyes and vision, though the exact location of the eyes and their use depends on the specific type of snail.

What kind of eyes does a pulmonate snail have?

In the case of the Pulmonates [lung breathers] who have two pairs of tentacles, the eyes sit at the tip of the top pair. Snails have very poor vision. Even though they have a lens on their eye, they have no muscles to focus the images. They can sense light and dark and work out where the light source is.

Is it true that snails have a sense of smell?
