The sea turtles are coming ashore on the beaches of Manasota Key, the barrier island just west of Englewood, a 40-minute drive directly west of our home. During the night, Loggerhead, Green, and Kemp's Ridley turtles climb from the water and travel across the sand to lay eggs from May through October on Gulf of America beaches. Car headlights are prohibited at night during these months in the parking lots fronting the beach, as they would disturb nesting female turtles and their hatchlings, who navigate by light. The car's strong artificial light overwhelms the subtle natural clues of moonlight and starlight reflecting off the water that the turtles rely on. Even streetlights and house lights can create false horizons for the turtles whose eyes have adapted to dim, blue-toned natural lights. The nests consist of holes in the sand dug by the turtles. Once her eggs have been laid in the hole, she covers them with sand and then makes her way back to the water. Both she and her hatchlings will return to the beach where they were born to continue their species in this way, exhibiting one of the most amazing feats of navigation in the animal kingdom. Marked nests were visible in several locations on the beach when we visited this past Monday, June 15th.
Previously, I have seen sea turtles in the Atlantic Ocean from a boat, but we have not gone out on a boat in the Gulf, so I can't claim to have personally seen our turtles in the water here. We will also miss seeing them on the beach, as we avoid night driving. It would be fun, though, to be with those who monitor the turtles at night on just one occasion to actually see these creatures complete their mission.
