Adaptations for Survival
|Sea turtle's have modified forelimbs that are shaped like long paddle-like flippers used for swimming. Because of these long wing-like adaptations green turtles can swim at about .9-1.4 mph and leatherbacks at about .9- 5.8 mph.|
Since sea turtles are ecothermic, they have a slow metabolic rate. This slow metabolic rate allows them to be submerged for long periods of time. Also during long dives, blood is kept away from tissues tolerant of low oxygen levels and pushed towards the heart, brain, and central nervous system. In order to retain more oxygen, leatherbacks have high concentrations of red blood cells. Also leatherback's muscles have a high concentration of myoglobin, which transports and stores oxygen within the muscle tissue.
|Sea turtle have a salt gland to rid their bodies of excess salt. This gland is located at the sea turtle's eyes and when the female turtles leave the ocean to lay their eggs on land it appears as if they're crying because their bodies are excreting salt and fluid in order to maintain equilibrium.|
