Sensory organs of gastropods
The
Olfactory organs
In terrestrial gastropods the most important sensory organs are the olfactory organs which are located on the tips of the 4

Eyes
In terrestrial pulmonate gastropods, eye spots are present at the tips of the tentacles in the
Some gastropods, for example the freshwater apple snails (family Ampullariidae)[7] and marine species of genus Strombus[8] can completely regenerate their eyes. The gastropods in both of these families have lens eyes.

Statocysts
In the statocysts of Haliotis asinina was found the expression of a conserved gene (Pax-258 gene), which is also important for forming structures for balance in eumetazoans.[10]

The mechanoreceptors are very crucial to the snail's sensory.
