The black caiman (Melanosuchus niger) is one of the largest predators in South America, yet we know little about adult diets. We studied stomach contents of adults in Guyana and found the largest individuals target mammals instead of fish and males exhibit cannibalism, a behavior never recorded for this species previously.
