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.
Terrestrial pulmonate snails have a hermaphroditic gonad producing egg cells as well as sperm cells. In a Roman snail's hermaphroditic gland, however, this happens at different times, so there can be no self-fertilization. On the other hand this exactly is what may happen in other snail groups (see below).
