More than 6,000 sea creatures make their home here at one of the most ecologically minded aquariums in the nation. In the indoor Stingray Bay and Shark Lagoon exhibits, bonnethead sharks prowl a 30,000-gallon tank along with other exotic fish, while Sunlit Seas features species that thrive in estuaries and coral reefs. Don't miss frolicsome sea lions performing in the Marine Theater, or the Challenge of the Deep attraction, which "submerges" visitors to explore diverse sea life and the resting place of the Titanic. Outdoor habitats hold penguins, sea lions and the aquarium's three beluga whales.
