Abstract

Gut proportions in four small-bodied Amazonian cebids (Callicebus caligatus, Callicebus moloch, Pithecia irrorata, and Saimiri madeirae) are reported and compared in the context of known differences in feeding ecology. The gastrointestinal tracts of both Callicebus and Pithecia were found to be relatively undifferentiated, as expected from their predominantly frugivorous diets. In Saimiri, the marked dominance of the small intestine correlates with a highly insectivorous diet. © 1995 Wiley-Liss, Inc.
