i think you mean what is a Mollusk?
Mollusks are invertebrate animals belonging to the Phylum Mollusca. They have a soft body consisting of a visceral mass containing the internal organs, a muscular foot used for locomotion, and, in all mollusks except the bivalves, a head. In addition to the mouth, which may be located at the end of an elongated organ called a proboscis, the head often bears sensory tentacles and eyes. The mouth leads into a chamber known as the pharynx, which usually contains a radula, a flexible, ribbon-like structure consisting of numerous rows of minute teeth, used in obtaining food. In all mollusks the body wall surrounding the visceral mass is prolonged into a fleshy or sheet-like mantle, which usually contains glands that secrete the shell.
All molluscs belong to the taxonomic domain of Eukarya.Eukarya covers all organisms in the Kingdom Animalia, as well as the Kingdoms Plantae, Fungi and Protista.
Which organ do most mollusks and crustaceans use to obtain oxygen?
Gills, in the shell in molluscs, and between the hind legs in crustaceans.

Why are many gastropods monoecious?
it is because of hormonal changes at different stages of their life cycle. many gastropods during their juvenile stage will be males and as they get older they will become females. also you have to take into account that there are environmental changes that also affect their behavior.
