The tentacles, eyes, osphradium, and statocysts act as the sensory organs. The nervous system of snails, like that of all molluscs, is basically different from vertebrate nervous systems. I first discuss how the embodiment concept explains covariation of body form, nervous system organization, and level of behavioral complexity using the mollusca as an example.
