The distinctive black-headed python does indeed have a black head and neck, which contrasts strongly with the brown banding along its body. The banding is light to dark brown or orange-brown on a base that can be creamy white, light brown and occasionally even yellow. The head is slightly pointed and barely distinct, in shape, from the body. The snakes grow to 3 metres and have a muscular body. Black-headed pythons are non-venomous and harmless to humans.
