==Description==

The Burmese python is a dark-colored non-venomous snake with many brown blotches bordered by black down the back.

In the wild, Burmese pythons typically grow to {{cvt|5|m}},<ref name="Smith" /><ref name="Campden"/> while specimens of more than {{cvt|7|m}} are unconfirmed.<ref name="Barker2012">{{cite journal |author1=Barker, D.G. |name-list-style=amp |author2=Barten, S.L. |author3=Ehrsam, J.P. |author4=Daddono, L. |title=The corrected lengths of two well-known giant pythons and the establishment of a new maximum length record for Burmese Pythons, ''Python bivittatus'' |journal=Bulletin of the Chicago Herpetological Society|volume=47|issue=1|pages=1–6|date=2012|url=http://www.vpi.com/sites/default/files/Barker-et-al_CorrectPythonLengths_2.pdf|access-date=2020-03-02}}</ref> This species is [[sexually dimorphic]] in size; females average only slightly longer, but are considerably heavier and bulkier than the males.
