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

Figure 6

(A) SEM images of one radula from specimen of control group, with depicted zones (degenerative zone, working zone, unworn teeth); schematic illustrations of teeth (drawn with Adobe Illustrator CS 6) were plotted on the SEM image to allow identification of tooth schemes (EG), scale bar = 200 μm. (BD) Schemes (drawn with Adobe Illustrator CS 6) of the sandpapers used ((B) rough, (C) medium, (D) fine) scaled identically to tooth scheme dimensions (EG). (EG) Schematic illustration (drawn with Adobe Illustrator CS 6) of tooth types (inner 15 marginals: stylus = yellow, cusps = orange; lateral I: basis and stylus = purple, cusp = light purple; lateral II: basis = green, thickening = dark green) of every second row (tooth rows 1–11), to depict area loss due to the sandpaper-tooth contact (wear patterns) for each sandpaper type (rough, medium, fine). (H) Degree of wear from posterior (slightly worn) to anterior (greatly worn).
