Hiking through Clifton Gorge, we stopped to observe all kinds of aquatic life at the Blue Hole–large  leatherback turtles, some swimming with young on their backs, a huge water snake (moccasin?) speeding through the water, large and small fish, probably carp, little birds swooping in to catch a water meal, and one big goose serenely floating right past us.  It was fascinating to pause to watch the water show.
