Black-headed Python

found across the Northern third of Australia, form arid deserts through to monsoonal tropics, it is most common in savannah woodlands. The head is black it looks like if it had been dipped into tar, which probably accounts for its common name tarpot. The reason for the black head is it acts like a solar panel so the snake can hide in its burrow and only the head needs to be out to warm up the blood of the snake, this protect the snake from being preyed on. They grow to 3 metres and weighing up to 16kgs.
