Burmese Python is another famous Python species found in Himalayan and North-east region of India and several other South-east Asian countries. For a long time it was considered as subspecies of Indian Rock Python (P. molurus) but now placed as separate species. Morphologically both species looks same in size and patterns. However these two species does not overlaps in greater part of their geographical distribution. Both species can be differentiated mainly by checking side blotches which are larger and definable in former and much smaller in P. molurus. In scalation these two can be differentiated by checking subocular which is found in P. bivittatus and clearly excludes supralabial from eyes while in P. molurus supralabial remain in contact with eyes.

Indian Rock Python is one of the most famous and one of the largest growing snake of India. In most of the parts of country this is the largest species (excluding North-east where Burmese Python is found in pleace of Indian Rock Python). Most of the times it can be easily identified by checking its large size, dark irregular patches, pinkish head and slow locomotion.

They are the world's longest snakes and longest reptile, but are not the most heavily built. Like all pythons, they are nonvenomous constrictors and normally not considered dangerous to humans. It is an excellent swimmer. The color pattern is a complex geometric pattern that incorporates different colors. The back typically has a series of irregular diamond shapes flanked by smaller markings with light centers. In this species' wide geographic range, much variation of size, color, and markings commonly occurs.
