The adult smooth-fronted caiman has cryptic habits and is seldom observed by day because it hides in underwater burrows or may spend much of its time up to 100 m (330 ft) away from water, concealed in dense undergrowth, in hollow logs, or under fallen trees.[1] Males are territorial and females have small home ranges.[2] Adults are semiterrestrial and mainly feed on such animals as porcupines, pacas, snakes, birds, and lizards, consuming few fish or molluscs.
