Living Coral Reef

Located in the Coral Reef Room is a giant living coral reef with several thousand inhabitants. Most of our living corals were donated from Player’s Island Casino. Our exhibit was created from what Player’s Island public relations department billed as “The World’s Largest Living Inland Reef.” See what living corals look like and how shrimps, fishes, sea stars, tube worms, anemones, etc. interact within this compact ecosystem. Observe the different shapes of tentacles of each coral and how they sway in the current. Corals are relatives of jellyfish and sea anemones, all of which have nematocysts or stinging cells to sting their prey. Tiny shoots of harpoons inject poison to immobilize their prey.
