Table 3 Calculated tooth volume of the teeth (lateral I, lateral II, inner 15 marginal teeth) present in every second row (tooth row 1 = outermost row [oldest and most frequently used one]; tooth row 11 = first [youngest] row with slight signs of wear) after foraging on sandpaper (rough, medium, fine), in %, estimated by manipulating the 3D model until it looks similar to worn teeth.

From: Feeding experiments on Vittina turrita (Mollusca, Gastropoda, Neritidae) reveal tooth contact areas and bent radular shape during foraging
