Fodor's Expert Review Maritime Aquarium at Norwalk
This 5-acre waterfront center, the cornerstone of the SoNo district, explores the marine life and maritime culture of Long Island Sound. The aquarium's more than 20 habitats include some 1,000 creatures indigenous to the sound, including stately loggerhead sea turtles, happy harbor seals, and the dozens of jellyfish that perform their ghostly ballet in "Jellyfish Encounter." You can see toothy bluefish and sand tiger sharks in the 110,000-gallon Ocean Beyond the Sound aquarium. The aquarium also operates an Environmental Education Center and leads marine-mammal cruises aboard the Spirit of the Sound, and has a towering IMAX theater.
