April 19, 10am -11:30am. An Advanced Florida Master Naturalist will be in the park to share information on shells and the mysterious creatures that reside inside.  Find out how shells are created, learn about behaviors, anatomy, and some fun facts. There will be opportunities to hold and see the shells of species that live in the Gulf of Mexico and Estero Bay. The session is informal, and attendees may come and go to suit their schedules.
