Opisthobranchia and Prosobranchia are two subclasses of gastropod mollusks. The main difference between them is the position of the gills: Opisthobranchia have their gills located behind the heart (opisthobranch), while Prosobranchia have their gills in front of the heart (prosobranch). Opisthobranchs are often marine and have no (or reduced) shells, while Prosobranchs typically have well-developed shells.
