Slug is a common name that is normally applied to any gastropod mollusc that lacks a shell, has a very reduced shell, or has a small internal shell. This is in contrast to the common name snail, which is applied to gastropods that have coiled shells that are big enough to retract into.

I've moved this slug from the Arthropods category to the Other category for you. Arthropods have exoskeletons -- think spiders, dragonflies, crabs.
