The Mary River turtle is a rare freshwater turtle that lives only in the Mary River in Australia. It has a very long tail and special organs in its cloaca that allow it to breathe oxygen directly from the water without surfacing.
The Mary River turtle differs from other turtles with its very long tail and the ability to breathe underwater through its cloaca. It is important for the river's nature because it helps maintain water cleanliness and is part of the local food chain. The species is endangered due to pollution and changes in the riverbed.
Immature form that undergoes metamorphosis before adulthood.
