One of the biggest tourist attractions in Boston is the New England Aquarium, which boasts of over 1.3 million visitors a year. There are great exhibits from different ocean environments. The New England Aquarium houses seadragons, turtles, sharks, jellyfish, seals, penguins, and more! The Great Ocean Tank is a four-story coral reef exhibit where there is always something to see. There is even a hands-on learning area where you can explore the touch tank with sea stars, horseshoe crabs, and sea urchins. For people that are less interested in the marine wildlife there is also an IMAX Theatre.
