Essentially, the only difference between slugs and snails is that snails carry coiled shells on their backs while slugs don't. Both have eyes at the tips of short stalks arising below the base of much longer, more slender tentacles-these tentacles feel what the simple eyes may not see.
The class Gastropoda includes snails and slugs of all kinds and all sizes from microscopic to large. There are many thousands of species of sea snails and sea slugs, as well as freshwater snails, freshwater limpets, land snails and land slugs.The class Gastropoda contains a vast total of named species, second only to the insects in overall number.The fossil history of this class goes back to the Late Cambrian.There are 611 families of gastropods known, of which 202 are extinct and appear only in the fossil record.owever, eyes in gastropods range from simple ocelli that only distinguish light and dark, to more complex pit eyes, and even to lens eyes. In land snails and slugs, vision is not the most important sense, because they are mainly nocturnal animals.
