The Burmese python (Python bivittatus) is one of the five largest species of snakes in the world (about the third-largest as measured either by length or weight). It is native to a large variation of tropic and subtropic areas of South and Southeast Asia. Until 2009, it was considered a subspecies of Python molurus, but now is recognized as belonging to a distinct species.
They are often found near water and are sometimes semi-aquatic, but can also be found in trees. Wild individuals average 3.7 m (12.1 ft) long, but have been known to reach 5.74 m (18.8 ft).
Burmese pythons are dark-colored snakes with many brown blotches bordered in black down the back. The perceived attractiveness of their skin pattern contributes to their popularity with both reptile keepers and the leather industry. The pattern is similar in colour, but different in actual pattern from the African rock python (Python sebae), sometimes resulting in confusion of the two species outside of their natural habitats. The African rock python can generally be distinguished by its tighter pattern of markings, compared to the Burmese python, which has bolder patterns, similar to those seen on a giraffe.
