Abstract

A lever model of jaw action indicates that the maximum bite force of white-lipped peccary (Tayassu pecari) should be at least 1.3 times that of collared peccary (T. tajacu) on food items of a given size. This prediction is consistent with the measured resistances of seeds and nuts that are eaten by the two species at a rain forest site in southeastern Peru. Such a difference in bite force, in association with differences in group size and digging ability, may be a basis for coexistence of the two species in Neotropical rain forests.
