WATER PYTHON Katrinus fuscus (Peters, 1873)
Sometimes measuring nearly 3 metres in length, this snake averages about 2 metres. It is found throughout tropical Australia, usually near water.
The scalation is smooth with 41-55 mid-body rows, 270-300 ventrals, single anal and 60-90 paired subcaudals.
The Water Python is most common in swampy localities, and is particularly common around the large grassy swamps at the top end of the Northern Territory. This nocturnal snake feeds on a variety of vertebrates, and is a major predator of young crocodiles.
About ten eggs are laid at the beginning of the wet season. These hatch about eighty days later, with the young measuring about 45 cm.
