In Mollusca, each eye is located upon a stumpy peduncle called ommatophore.
Mantle, a loose skin fold, dorsally covers Mollusca body and encloses a mantle cavity. It further contains rectum, genital duct, a penis and a small chemoreceptor called Osphradium.
The large, oval aperture or mouth of the shell can be tightly closed by a thick, plate- like operculum attached to the foot.
