The New England Aquarium in Boston showcases marine life from all over the world. Its main attraction is the Giant Ocean Tank, a cylindrical exhibit that mimics a Caribbean coral reef. It houses Myrtle, the green sea turtle, loggerhead sea turtles, and various tropical fish. Visitors can see the exhibit from all angles through 67 acrylic windows on a spiral walkway. The aquarium also has a shark and ray touch tank, where guests can interact with multiple species of stingray and sharks.
