Turtles have the ability to breathe out of their front sides as well as their back sides — yep, turtles can breathe through their bums. Their respiratory muscles expand, drawing in air from the front and back sides of their shells. When their heads are submerged, most turtles have the ability to draw air in through a bursae sac in their hind end, removing the need for the turtle to come up for air.
