The Northern Snake-necked or Long-necked Turtle (Chelodina [Macrochelodina] oblonga [until recently referred to as rugosa]) is a common turtle of the lowland freshwater areas of northern Australia.
This video was filmed in a rainforest spring in the catchment of the Finniss River in the Northern Territory, Australia.
The Northern Snake-necked Turtle is a much sort after food source by the local Aboriginal people.
The back legs and tail of a small Freshwater Crocodile (Crocodylus johnstoni) is visible along the left hand edge of the screen just above the centre about half way through the video.
