The slug is a unit of mass associated with Imperial units and United States customary units. It is a mass that accelerates by 1 ft/s 2 when a force of one pound (lbF) is exerted on it.
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. Both slugs and snails have either a dark green, tan, light gray, or black body. Some of the varieties have patterns or spots on their bodies.
