From Wikipedia, the free encyclopedia. In addition to its use as a snorkel, the unusual snout is equipped with sensory receptors that allow the turtle to locate prey in murky water or sand 9.

Pig-nosed turtles inhabit freshwater and estuarine bodies of water. Males never come out of the water and females only come out when they are about to lay eggs. In New Guinea, pig-nosed turtles are hunted for meat. Smithsonian Institution Press, Washington D.

They also retain a solid plastron, connected to the carapace by a strong bony bridge, rather than the soft margin of the trionychids. At hatching, nutrition comes from the left-over yolk of the egg.
