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.
According to the Sea Turtle Conservancy, sea turtles can hold their breath for much longer periods of time. A sea turtle that is not engaged in strenuous activity is able to hold its breath underwater for anywhere from 4 to 7 hours. However, when a sea turtle is hibernating, it may stay underwater for several months at a time. Turtles are able to stay underwater for long periods because of their ability to metabolize oxygen at a very low rate.
