When the tide is low, they sit still on the sand or rock and dry their shells. I seem to find them more often on beaches where snorkeling is especially great. Having enjoyed the sun, they slowly moves and swim back to the ocean as the tide gets higher. They live by the clock of the nature. No hurry.
In Japan their is an old saying that a turtle lives for ten thousand years. What's the secret of longevity? Obviously they don't try to go faster than they have to.
