where does the sand in destin come from
Destin, Florida "Crab Island," was actually two islands made from sand that the Army Corps of Engineers dredged up from the East Pass. These islands were large enough to inhabit sea grass, small shrubs and nesting seabirds. It has been reduced to a significant sandbar, which appears only when the tide is out. It has become a popular anchorage[15] in the area. The entrance to Destin Harbor, a lagoon between the beaches and the main body of the western portion of the peninsula, is located just north of the East Pass jetty. The lagoon is formed by a sand spit named Holiday Isle; many condominiums have been built along the harbor since the 1970s.[12]
Sand dollar The bodies of adult sand dollars, like those of other echinoids, display radial symmetry. The petal-like pattern in sand dollars consists of five paired rows of pores. The pores are perforations in the endoskeleton through which podia for gas exchange project from the body. The mouth of the sand dollar is located on the bottom of its body at the center of the petal-like pattern. Unlike other urchins, the bodies of sand dollars also display secondary front-to-back bilateral symmetry. The anus of sand dollars is located at the back rather than at the top as in most urchins, with many more bilateral features appearing in some species. These result from the adaptation of sand dollars, in the course of their evolution, from creatures that originally lived their lives on top of the seabed (epibenthos) to creatures that burrow beneath it (endobenthos).
