LM of Waved Whelk tooth and radula

Light micrograph in interference contrast illumination of a tooth plate on the radula of the Waved Whelk (Buccinum undatum). The radula is a strip-like organ studded with rows of horny tooth plates. B.undatum has a rachoglossate radula, in that each row contains only three tooth plates. In this image, the centre tooth plate in a row is seen with seven tooth-like projections from the edge of the plate. The radula is used to rasp food, in this case the corpses of marine animals, into particles that are small enough to digest. Magnification x200 at 35mm size
