This species characteristically have black speckling on the dorsal surface of its grey-colored body; however, juveniles lack this pigmentation. In rare cases adult specimens may also lack the characteristic speckling. The ocular tentaclesTentacles:
Sensory projections on the head end of a mollusc. There are generally two pairs; upper (posterior) and smaller, lower (anterior). The upper pair bears the eyes. In many snails the eyes are located at the tips of this structure; however, in Basommatophoran snail species, the eyes are located at the base of the tentacles.
