Loggerhead turtles typically are found in shallow coastal waters, bays and lagoons. They are cold-blooded and have a slow metabolic rate. They can easily stay submerged for more than 45 minutes.
Sea turtles have a special adaption for diving.
In comparison, we use oxygen in all areas of our body. But diving turtles can shut down the oxygen to certain areas of their bodies, keeping as much oxygen as possible for the crucial systems, such as the heart, brain and central nervous system. These turtles are diving experts. The green sea turtle can dive for five hours. Loggerheads have jaws adapted for crushing and grinding.
