It sits dockside on Boston Harbor, and along with a jam-packed main exhibit hall, there are outside exhibits, a sea lion show in a separate building, and an Activity Center located across the street. An extensive medical center treats injured sea mammals and reptiles some of the labs are visible behind glass so that equipment and staff are on display. It s a big responsibility, and although you won t see the injured animals, take the time to look at the labs that treat them. What you will see here are penguins, tanks and tanks of fish, shellfish, crustaceans, and every water habitat imaginable. In the center of the main hall is the Giant Ocean Tank a four story, round tank filled with saltwater fish, sharks, sea turtles, rays, a coral reef and its tiny inhabitants.
Divers enter the tank five times daily.
Thanks to the ramp that skirts it, the tank is easily accessible, even on crowded days. Once you ve reached the top, go upstairs and look down inside it. The view is different and the turtles often surface for air. Around the perimeter of the big tank are three levels of other exhibits. In addition, there is a new section on the lower lever just at the entrance.
