Sensory organs of gastropods Sensory organs of gastropods The sensory organs of gastropods (snails and slugs) include olfactory organs, eyes, statocysts and mechanoreceptors. Gastropods have no sense of hearing. In terrestrial gastropods the most important sensory organs are the olfactory organs which are located on the tips of the 4 tentacles. In opisthobranch marine gastropods, the chemosensory organs are two protruding structures on top of the head. These are known as rhinophores.
