Located on the shoreline of Nantucket Harbor, the Aquarium displays local Nantucket species and is an excellent place to learn about the amazing sealife around the island. Displays are always changing and range from crabs and shellfish to fish and eels. All animals at the Aquarium are locally-collected and are released back into the wild at the end of the season. Displays can also include anything from seahorses to octopus to sharks!
The slideshow above shows pictures from the Aquarium microscope taken over several years. The microscope displays interesting microscopic things all summer long.
Thank you for an exciting summer!
Fish that would not survive the cold water have moved to the Natural Science Museum. These include permit, jack crevalle, flying gurnard, and a snowy grouper. The seahorses made the move too!
Thank you local fishermen and charter captains who brought many of the bigger animals this summer. Just Do It 2 brought in trigger fish and striped bass, among others. Critter Cruises has donated all sorts of creatures from searobins to black seabass.
Also thanks to Shearwater Excursions for taking out Aquarium Interns each week to help on their seal tours. This is a great way to get out onto the water!

Outdoor Circle Tank
One of the larger tanks at the Aquarium, the circle tank is home to large fish, dogfish (small sharks), spider crabs, and horseshoe crabs. It overlooks the harbor and is a perfect place to contemplate the natural beauty of Nantucket.
Each room is filled with more than 50 animals including trigger fish, lobsters, mantis shrimp, tropical fish, and common local species. All the animals are either caught by our staff during research trips or donated by local fishermen and fishing charters. Exhibits change weekly to highlight new species or local ecosystems. There is always something new to discover!
