As sea turtles are air breathing reptiles, they need to surface to breathe. Sea turtles can hold their breath for several hours, depending upon the level of activity. A resting or sleeping turtle can remain underwater for 4-7 hours.
Depending on the species, a turtle can stay under water for hours, days, weeks or even months. Turtles that spend large amounts of time submerged have developed specialized means of capturing oxygen from the surrounding water via gills, special cells or their skin.
