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.
Differences in Shell. The long body and tentacles of slug is very similar to those of a snail, but the main physical difference between the two species is the shell.The snail uses its shell as an external attachment to protect and cover its body.The slug, however, has a small inner shell, which lies underneath the skin. Slugs and snails both breathe through an air hole on their mantle, called a pneumostome. On snails, the pneumostome lies is juxtaposed next to the shell.he snail uses its shell as an external attachment to protect and cover its body.
