Bullia digitalis, the finger plough shell, plough snail or surfing snail, is a species of sea snail, a marine gastropod mollusk in the family Nassariidae, the Nassa mud snails or dog whelks.

The snails are a unique part of the neuston, organisms which live on or near the surface of the water, because of their relatively large size. They have veliger , or free swimming larvae, but the adults do not swim, and cannot create their rafts, except at the surface where air bubbles are available.
Planorbarius corneus is the largest European species of ramshorn snail (family Planorbidae), with a shell typically measuring 35 millimetres (1.4 in) across when fully-grown. [ 4 ] The 10–17 by 22–40 millimetres (0.39–0.67 by 0.87–1.57 in) coiled shell has between 3 and 4.5 rounded whorls with deep sutures , the last whorl predominating.
