Main Ref. Lowe-McConnell, R.H., 1984
Remarks This species is usually solitary. Adults stay in flooded forests during first 5 months of flooding and consume but fruits and grains. Young and juveniles live in black waters of flood plains until their sexual maturity. Feeds on fruits and nuts of palm and rubber trees. In low water season, feeds on feces, fish, algae, wood, leaves and detritus. Has strong teeth that can chew hard nuts that fall in the water during flowering season. Juveniles are omnivores (Ref. 51869).
