The subradular organ is a sensory organ below the grinding mouthparts (radula) of some molluscs, specifically the chitons.
[1] This organ is involved in chemoreception - that is, in judging the nature of food or the substratum.
In this sense, it can be considered a 'smell' or 'taste' organ; food is sensed before each stroke of the radula.
