This kid-friendly aquarium has several different exhibits around its central courtyard. Penguins, otters and seals frolic in the Sea Cliffs display. The sea-lion show is the big draw, taking place in an outdoor Aquatheater with stadium seating. The 'Ocean's Wonders: Sharks!' exhibit features various species of the fearsome fish in a 500,000-gallon tank with a tunnel you can walk through. (Please note that animal welfare experts say being kept in captivity is stressful for sharks.)
