River Fitzroy turtle inhalation through the secretory sinus in the buttock.

Observations by the scientists showed that in the buttock of this turtle there are two very smooth large follicles, smooth follicles that can help the real secretion of the sinuses (intestine, ureter, gonads of some fish and birds, amphibians, reptiles are all in a sinus) taking oxygen in the water to extend the time they dive underwater.

In fact, most like turtles snapping turtles (North America's largest freshwater turtle) can also take air in the water through real sinuses. In 2002, Toni E. Pries and Craig E. Franklin studied the Fitzroy River turtle, showing that their ability to breathe through their secretory sinuses could reach a level where no turtles could catch up. The amount of air that snaps turtle normally inhales through sinusitis only accounts for 4% of the total air intake, while in the Fitzroy turtle this is 41%, which proves close to half the amount of air they breathe through the sinuses in the buttock.
