Shells of the freshwater snail Theodoxus danubialis Shells of the land snail species Helicina rostrata Titiscania, a shellless neritimorph. Despite their relatively low diversity, with only around 2,000 species, neritomorphs have achieved a remarkable diversity of forms, resembling a smaller-scale version of the diversity achieved by Gastropoda as a whole.
