The black caiman (Melanosuchus niger) is a crocodilian reptile endemic to South America. With a maximum length of around 5 to 6.5 m (16 to 21 ft) and a mass of over 450 kg (1,000 lb), it is the largest living species of the family Alligatoridae, and the third-largest crocodilian in the Neotropical realm. True to its common and scientific names, the black caiman has a dark greenish-black coloration as an adult. In some individuals, the pigmentation can appear almost jet-black. It has grey to brown banding on the lower jaw; juveniles have a more vibrant coloration compared to adults, with prominent white-pale yellow banding on the flanks that remains present well into adulthood (more than most other species). The banding on young helps with camouflage by breaking up their body outline, on land or in water, in an effort to avoid predation. Wikipedia →
