The Fitzroy River turtle, Rheodytes leukops, is a freshwater turtle found only in central Queensland’s Fitzroy River drainage. It is often called a bum-breathing turtle, but the scientific term is cloacal respiration: specialised sacs in the cloaca exchange gases with the water.
A turtle linked to healthy river flow
This species is closely associated with clear, well-oxygenated running water, especially riffle habitat. It can also use other parts of the river system, so it should not be described as living only in rapids. Clean water, natural flow patterns and suitable refuges all matter to its survival.
Why its breathing adaptation matters
Cloacal respiration helps the turtle remain underwater for long periods, particularly when water is cool and oxygen-rich. It does not make the turtle independent of air or immune to degraded habitat. Sediment, altered flows and reduced oxygen can affect the river conditions on which this specialised breathing system depends.
Conservation needs
The Fitzroy River turtle is listed as Endangered under Australia’s national environmental law. River regulation, sedimentation, habitat disturbance, nest predation and changes to catchment land use can all create pressure. Conservation work is strongest when it protects river processes as well as individual nests and hatchlings.
How to describe it accurately
Colloquial names can help people remember the species, but they should not replace the biology. The Fitzroy River turtle is a distinctive Australian freshwater turtle with an exceptional form of aquatic gas exchange. Its story is about river health, not a novelty trick.
