The Broad-snouted Caiman is found in northeastern South America.
There is marked sexual dimorphism, with females being noticeably smaller. In addition to its colouring, it can be distinguished from similar species by its short, robust snout, which is as wide as its head, and the larger size of the protective plates on its neck.
Each clutch contains between 20 and 50 eggs and the incubation period is about 70 days. The female protects her nest and the hatchlings call out to their mother a few days before hatching.
The main threat faced by the Broad-snouted Caiman is the destruction of its habitat and, to a lesser extent now, hunting for its skin, which was once highly sought after, causing it to have been seriously endangered in the past.
