Does a sea turtle have gills?

Answer 1

No, sea turtles have lungs that can quickly refill when they come up to breathe on the surface of the water. Green and Loggerhead turtles can hold their breath for about 4 to 5 minutes during a routine activity. But Loggerheads are known for longer dives.

Answer 2

Sea turtles have lungs, not gills. They hold their breath - which they're very good at - when they dive.
