Sanibel Island

Clip | 9m 46s

Sanibel Island is a barrier island, a term for long, straight, parallel islands separated from the mainland by lagoons and bays. Since they are parallel to the shoreline, they act as barriers for the mainland against the destructive actions of the ocean. They form as a result of the transportation and deposition of sand by winds, tides, and the ocean.
