A black-headed python, scientifically named Aspidites melanocephalus is a medium-sized member of the python family of snakes. An adult black-headed python averages about 4-5 feet in length (1.2-1.5 m) and weighs 6-15 pounds (2.7-6.8 kg), with the female usually larger than the male. Black-headed pythons are thick, muscular snakes and have a striking physical appearance that makes them one of the easiest species of python to identify. The head, neck and throat of these snakes is a striking, glossy jet-black color, and the rest of its body ranges from cream or yellow to a dark brown color. From its neck to the end of its tail, the black-headed python has a series of 70-110 wavy bands that range in tint from black and dark brown to a reddish color.
Geographically, the distribution of black-headed pythons is confined to the continent of Australia. Within Australia, the black-headed python is found only across the northern third of the country. As a species, it is commonly encountered in Queensland, the Northern Territories and West Australia.
The black-headed python is found in a variety of habitats ranging from semiarid scrubland to open woodlands, temperate forests and tropical rainforest. This type of python will seek shelter under debris on the ground, in burrows and clumps of grass or in hollow logs. Although the black-headed python is an excellent climber, it is a burrowing snake and prefers to remain on the ground. Instead of basking in the sun for heat and putting itself in danger from predators, this snake will often remain in its burrow and just push its head out. Its black head serves as something of a solar panel and warms the entire body.
Black-headed pythons are carnivores whose diet consists mainly of other cold-blooded reptiles. In fact, because of its preference for cold-blooded prey, the black-headed python lacks the infrared sensing pits around its mouth that other species of pythons use to detect heat. Although black-headed pythons eat lizards and frogs, a significant portion of their diet consists of venomous snakes. Black-headed pythons seem to be immune to the venom from the most toxic Australian snakes. Occasionally, these snakes will eat birds and small mammals.
Prior to breeding, male black-headed pythons are known to sometimes engage in combat and bite each other. Mating might from about 20 minutes to six or seven hours. Females lay clutches of about eight eggs. The female black-headed python stays coiled around her clutch until the eggs hatch, usually in about 60 days.
