Sea Turtle closeup Although many turtles spend much of their lives underwater, all turtles breathe air and must surface at regular intervals to refill their lungs. They may also spend much of their life on land. Aquatic respiration in Australian freshwater turtles is currently being studied. Some species have large cloacal cavities that are lined with many finger like projections. These projections, called papillae, have a rich blood supply, as well as to increase the surface area of ​​the cloaca. Turtles can take up dissolved oxygen from water using these papillae, in much the same way that fish use gills to breathe.

    1. Original description from Irina:
      Хотя многие черепахи проводят много их жизнь под водой, все черепахи дышат воздухом, и должна поверхности через равные промежутки времени, чтобы пополнить свои легкие. Они могут также проводить большую часть своей жизни на суше. Водные дыхания в австралийском пресноводных черепах в настоящее время изучается. Некоторые виды имеют большие клоаки полости, которые выстланы многих пальцев, как прогнозы. Эти прогнозы, называемые сосочки , имеют богатое кровоснабжение, а также увеличить площадь поверхности клоаку. Черепах может занять до растворенного кислорода из воды с помощью этих сосочков, во многом таким же образом, что рыбы используют жабры , чтобы дышать.
