==Description== [[File:Prosobranchia.gif|thumb|left|Three views of a [[gastropod shell|shell]] of a ''[[Harpa]]'' species, a prosobranch gastropod.]] [[File:Naturalis Biodiversity Center - RMNH.MOL.129087 - Chicoreus ramosus (Linnaeus, 1758) - Muricidae - Mollusc shell.jpeg|thumb|left|''[[Chicoreus ramosus]]'', a prosobranch gastropod.]] The majority of prosobranchs have an [[operculum (gastropod)|operculum]], a [[corneous]] or [[calcareous]] plate situated on the [[Dorsum (biology)|dorsal]] surface of the foot. In many prosobranchs, the animal can completely close the [[aperture (mollusc)|aperture]] with the operculum. The nervous system of prosobranchs is twisted into a figure 8 due to a developmental process known as [[torsion (gastropod)|torsion]]. The eyes are situated at the base of the [[tentacle]]s.
