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!
Release day coming September 6! This event is free and runs from 10am to 1pm. By 1pm virtually all the animals have been released.
Here is a short video of some of the cool creatures you can see during your visit:
All Local Species
All of the animals displayed at the Aquarium are from Nantucket waters and things change every year based on what is found throughout the summer. No summer is the same as the one before!
The Aquarium depends on many local people for our exhibits. Local fishermen and charter captains bring many of the bigger animals this summer. Special thanks to Just Do It 2, Critter Cruises, and Sayles Seafood for lots of recent donations.
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!
