Sea Stars
Tropical Storm Hannah departed from Sunset Beach. NC, and Little River, SC, on 9/6/08. after making landfall the preceding evening. At low tide I found the island looking like Mars, with sea stars everywhere covered with sand. A woman and I rinsed them off in the inlet and sorted them.
I brought some sea stars home to save for researchers. Unfortunately, the "stone" of my aerator backed its way out of their container. Several died and broke. The grey sea star with black markings might be Astropecten duplicatus.
