Both slugs and snails are gastropods and belong to phylum Mollusca. Both have soft bodies with a muscular foot. Both slugs and snails are similar in many respects but with only a few differences. One of the noticeable differences is that snails have a shell on their backs whereas slugs do not have shells. The shell is coiled and about one to one and one-half inches long.
