Sealife enthusiasts will enjoy these two passes to the New England Aquarium.  Their 200,000 gallon tank is the centerpiece of the New England Aquarium, and it is one of the region's most popular underwater exhibits. The reef accommodates not only sharks, sea turtles, barracuda and moray, but also hundreds of smaller exotic tropical fishes, and it is one of the most detailed and scientifically accurate recreations of its kind.
