Do Sea Turtles Have Gills Or Lungs. The lungs are located right under the carapace and the vertebral column. A green turtle comes up for a breath, maldives.
Just like other reptiles, sea turtles have lungs. Instead of a diaphragm, they have muscles lining the inside of their shells to help push air in and out. They have a slightly different structure than mammalian lungs, but work just as well when it comes to exchanging gases (oxygen and carbondioxide).
