This banding fades only gradually as the animal matures. Structurally dissimilar to other caiman species, particularly in the shape of the skull. Has distinctly larger eyes, and a relatively narrow snout. The bony ridge extending from above the eyes down the snout, as seen in other caiman, is present. Shows more terrestrial hunting activity, particularly at night, having acute sight and hearing.
Juveniles take crustaceans before moving onto larger, terrestrial prey.
Larger adults have been reported to attack domestic animals and humans. Information concerning reproductive ecology is scarce. Nests can be found in both concealed and open locations. Females remain close to the nests. Once the eggs are ready to hatch, she will open the nest and assist in the hatching process.
