The other is Aspidites ramsayi , the woma. They have a narrow head, barely distinct from the neck and small black eyes that match the head color and are hard to distinguish. The snout is rounded and used for digging borrows which the animals are fond of. Native to Australia, Black-headed pythons occur from the sub humid forests in the north to the arid interior of the country. They are medium sized pythons with muscular bodies.
Females are generally larger than males and can reach ten feet in length.
It is believed that specimens from the western part of the range are smaller, with whiter ground color and more contrasted pattern. I am not sure this is accurate, as animals alleged to be of western descent have been known to reach relatively large size in captivity. Black-headeds are terrestrial and rock inhabiting pythons. In our habitats, we use a mixed substrate to allow them to burrow, as they are fond of doing. As mentioned, they will often stay entirely underground except for exposing the black portion of their head and neck.
