Resumo: The mammalian masticatory apparatus is a highly plastic region of the skull and thus subjected to singular ontogenetic trajectories. Here we present the first descriptive allometric pattern study of mandible among the capybara (Hydrochoerus hydrochaeris), based on the study of 37 specimens. Allometric changes in shape were analyzed using geometric morphometrics techniques and the pattern of allometry was visualized. A multivariate regression of the shape component on size, estimated by the logarithm of centroid size, appeared as highly significant. Therefore, a major component of shape variation in these mandibles is related to the attainment of adult size (i.e., growth).
