The pig-nosed turtle, an endangered freshwater turtle native to the Northern Territory and southern New Guinea, is unique in many respects. Unlike most freshwater turtles, it is almost completely adapted to life in water. It has paddle-like flippers similar to sea turtles, a snorkel-like "pig-nose" to help it breathe while staying submerged, and eggs that will only hatch when exposed to the waters of the wet season.
