Did you know?

  1. The great star coral in this exhibit was collected under permit in the Florida Keys National Marine Sanctuary. National marine sanctuaries protect natural and historical marine resources through education, research and management.
  2. When our excess carbon dioxide enters the water, the ocean becomes more acidic. This harms protective skeleton growth in corals and shell growth in lobsters, crabs and other shellfish.
  3. Want to help corals in the wild? Joining your community to reduce the use of fossil fuels is one way to keep our excess carbon dioxide out of the ocean and support corals reefs for generations to come.
