A ll modern mollusks have the same fundamental body plan. There are three distinct body zones: a head-foot, a visceral mass and a mantle. Some common features are 1  : Unsegmented soft body with bilateral symmetry.
Most molluscan species are readily recognizable as such. The Mollusca constitute a successful phylum; there are probably over 110,000 living species of mollusks, a number second only to that of the phylum Arthropoda, and more than double the number of vertebrate species.More than 99% of living molluscan species belong to two classes: Gastropoda (snails) and Bivalvia.ost molluscan species are readily recognizable as such.
