A view of a vegetated inland coastline overlooking the water on Dauphin Island, Alabama. The island protects mainland Alabama’s coastal communities and resources from storms, while also providing recreational opportunities (fishing, beach tourism, etc.) and other economic benefits to the local community and state.

“The ocean is the closest I can get to an unexplored world, without going into space... I mean, I feel a deep connection to the ocean and its constant rhythms, but when I visit, there's a new discovery or appreciation every time.

Diadema antillarum, the long-spined sea urchin, is an ecologically important species in Caribbean coral reef habitats where it controls algal growth and coverage and helps keep reef surfaces clear for corals to grow and settle. In early 2022, the remaining D. antillarum populations began experiencing mass mortality in the Caribbean.
