This undated photo provided by the Sanibel & Captiva Chamber of Commerce shows a junonia shell amid an array of seashells found on the beaches of Sanibel Island in Florida. The Gulf Coast barrier island is known for quiet beaches, wildlife and good opportunities for finding seashells, especially for visitors who are motivated to check tide tables and comb the beaches at dawn and after dark, when there’s less competition for spotting whatever the tide washes ashore.
