Get a scuba diver’s eye view without even getting wet when you visit the Giant Ocean Tank at the New England Aquarium. This 24-foot-deep tank holds about 200,000 gallons of Boston Harbor saltwater that is heated and filtered. The tank is home to a man-made reef with more than 3,000 corals and sponges, representing about 35 species found in the Caribbean. You can spy sharks, barracudas, sea turtles, and many other small exotic tropical fish.

The top of the Giant Ocean Tank is open to the public, where Aquarium staff host special discussions about the creatures you will find in the tank.

For those of you who want to sleep with the jellies, the Aquarium offers an overnight package, where children and adults can sleep overnight in the Amazing Jellies Exhibit. Every Friday and Saturday night throughout the school year, overnight visitors will have the opportunity to do science experiments and squid dissections in the Harborside Learning Lab. Visitors will also get to take a tour of the Aquarium the next morning before the building is open to the public.
