Mystic Aquarium & Institute for Exploration

This state-of-the-art aquarium boasts more than 6000 species of sea creatures, as well as an outdoor viewing area for watching seals and sea lions below the waterline and a penguin pavilion. The aquarium's most famous (and controversial) residents are the three beluga whales, who reside in the Arctic Coast exhibit. Animal welfare groups claim it is debilitating to keep whales in enclosed containers.
