How do snails taste?

a looks like a fat flat worm with eyes on tentacles and it has a shell in a spiral shape

A snail has a spiral shell, is usually small, has a soft squishy body with no legs, just a "tummy foot", and a land snail has two pair of tentacles, and the top pair, (longest) is its eyes, the bottom (shortest), is its feelers, sea snails have no bottom pair.
