That is why you can’t really see them unless there isn’t any dirt on them. The outside eyes are really touch sensors, but they are often covered in dirt. There are actually two pairs of snail eyes-two large ones on the outside which can be seen easily, and two small ones on the inside. Snails do have 4 eyes, but it’s hard to see them because they are so tiny. A snail’s eyes are much smaller than ours and they can barely tell if it is light out or dark.

Giant African land snails can see things that are about 1/4 of an inch in size. Talking about whether snails are blind, what about when it comes to snails and humans, can snails see humans? No, this is because humans are too large for snails to see. Their two large purple-blue eyes are situated on either side of the muscular foot at the base of their tentacles.įurthermore, since these creatures rely on feel and smell to move about, their eyes are useful for distinguishing light/darkness, rather than details about objects in the distance.

Talking of whether or not snails can see, what about when it comes to snail vision, or better yet, how does a snail see? A creature’s way of seeing depends upon hundreds of different kinds of light-sensitive cells made by special genes that fit together like puzzle pieces to give the cell a precise shape. Moreover, a snail’s eyes resemble a little black spot. They can therefore sense the enemy by smelling or hearing them. However, snails can only see straight ahead. Snail’s eyes are simple and near the top of its head or neck. Talking of whether snails have eyes, can snails see? Yes, snails have eyes on the end of their long feet.

However, their eyes are usually very small, so they can’t see anything that’s too far away, but they can see things like changes in light or the direction of approaching objects. They range in color and size depending on what species they are. Talking of snails and their character traits, what about when it comes to snails and sight?ĭo snails have eyes? Yes, snails have eyes. It is a tough journey as they need to shed their shell when they get too big for it. The snail’s shell is made up of calcium carbonate and its soft body inside is protected by this shell.
