Are snails gastropods

Introduction. Gastropods (class Gastropoda, phylum Mollusca) are comprised of more than 80,000 species and are differentiated from other classes of mollusca by the presence of a torsed body. They are separated into three subclasses: Prosobranchia, Opistobranchia, and Pulmonata. They are found in terrestrial, freshwater and marine environments.

Slugs and snails have a soft, unsegmented body that is 2 to 4 cm (.79 to 1.5 inches) long. The head has one or two pairs of tentacles.
