Feeding snapping turtles can stay underwater for a few hours. They can stay under so long because they do not need to burn oxygen to make their own heat because they are cold-blooded. Metabolizing oxygen at a very low rate is the key to a turtle's ability to stay underwater for long periods. For example, during winter hibernation, a turtle will bury himself in the mud at the bottom of a pond or lake. The water surrounding the turtle will remain at about 39 degrees F and will not freeze, allowing the turtle to extract oxygen from the water. The turtle's heart will only beat one time every 10 minutes during hibernation.Please sight a reference before putting inane remarks here. Snapping turtles are a fascination of of mine because of their unique pulmonary systems (easily the most efficient in the world).

Turtles have lungs, not gills. They don't breathe underwater. When they dive, they hold their breath.
