FIGURE 4 in Ecomorphology of main food processing structures of four ocypodid species: how do they relate to the crabs' trophic habits?

FIGURE 4. Variations in the dorsal urocardiac teeth from the gastric mills of crabs with different diets. A, a deposit-feeder, Uca sp. (Ocypodidae); B, vascular plant-eater, Aratus pisonii (H. Milne Edwards, 1837) (Sesarmidae); C, an opportunistic carnivore/ omnivore (believed), Helice tridens (De Haan, 1835) (Varunidae). Scale = 1 mm. (A, B, after Warner 1977: 91, fig. 28; C, after Sakai et al. 2006: 6, fig. 4C).
