Report Abuse. The word snail is a common name that can be used for almost all members of the molluscan class Gastropoda which have coiled shells in the adult stage. (Those snails which do not have a shell or only a very small shell are usually called slugs. Snails which have a broadly conical shell which is not coiled, or appears not to be coiled, are often known as limpets.) When the word snail is used in a general sense, it includes sea snails, land snails and freshwater snails.
