The woma python is distinguished from other Australian pythons by its narrow head which is barely distinct from the neck (2). It has small eyes, smooth scales, a broad body and a thin tail (3). This species is coloured grey, olive, brown or rich red-brown above, with several darker olive brown to black cross-bands on the body. The sides are paler and the underside is a cream to yellow colour, with pink or brown blotches (2). The woma python and its relative the black-headed python, do not have heat sensitive pits bordering the mouth like other pythons (4).
