Sea turtles have been swimming the Earth's oceans for more than 100 million years. They are air-breathing reptiles adapted to life at sea. They vary in size from the small Kemp's Ridley turtle that weights 100 pounds to the enormous leatherback turtle that can weight up to 2,000 pounds. Sanibel's beaches provide nesting ground for primarily loggerhead and green turtles.

One of the first and longest running sea turtle research and monitoring programs was started by Charles LeBuff here at the lighthouse in 1959. Today, over 100 SCCF volunteers monitor the beach daily from May to October. They look for the distinctive tracks left by female sea turtles coming ashore. Nests are marked for protection and monitoring. Three days after a nest hatches it is dug to inventory the nest.
