Fig. 3From: Ontogeny of the elemental composition and the biomechanics of radular teeth in the chiton Lepidochitona cinereaa, b Broken teeth (Ct, central tooth; Lt I, lateral tooth I; Lt II, lateral tooth II; Mt, marginal tooth) of a one dry, native radula and b one wet, treated radula. c Breaking force, mN, for each radular zone, tooth type, and condition (native dry, native wet, treated dry, treated wet) with quantity (n) of broken teeth. Brown colour highlight the results obtained by testing dry teeth and blue the results obtained from testing wet teeth. Scale bars: a–b =  200 μm. D, dry; W, wetBack to article page
