WATERFRONT. Marine-themed exhibits, programs, and demonstrations take place throughout the day at this spectacular, above-ground aquatic extravaganza. Seals, penguins, sharks, and other creatures reside at the aquarium, and a massive, four-story, 187,000-gallon tank features a living coral reef. The West Wing's unique glass and steel exterior mimics fish scales, and special exhibits change monthly. Whale watching excursions are offered seasonally as well.
