Our second-to-last landing on isabela leads us to a very unusual place. On a rocky coast, a natural channel filled with sea water exists, maybe 100 meters long, 2 meters narrow and rather shallow. Surrounded by sea iguanas, both sea turtles and black-tip sharks are breeding in this channel nearby. We see 5 or 6 sharks resting on the ground, and sea turtles swimming across them seemingly careless.
Close to the end of the channel there is a group of sea turtles mating. Let me be more precise: 1 female and N males, where N ranges from 1 to 4! Apparently someone has chatted up a guy from the swimming relay team.
