Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Sea turtles (superfamily Chelonioidea) inhabit all of the world''s oceans except the Arctic. Sea turtles are almost always submerged in water, and, therefore, have developed an anaerobic system of respiration. Although all sea turtles breathe air, under dire circumstances they may divert to anaerobic respiration for long periods of time. When surfacing to breathe, a sea turtle can quickly refill its lungs with a single explosive exhalation and rapid inhalation. Their large lungs have adapted to permit rapid exchange of oxygen and to avoid trapping gases during deep dives. However, turtles must emerge while breeding, given the extra level of activity.
