The country’s oldest marine aquarium, having been established in 1885, makes for a nice little 45-minute visit. Young children will particularly appreciate its charms. Time your visit to coincide with feeding time for the two seals in a special pool out in front of the museum. Their injuries—one is blind—make them unable to be released, so the aquarium is their permanent home. Feeding time is 11am and 4pm most days. The best parts of the aquarium are the touch tanks with lobsters, quahogs, horseshoe crabs, spider crabs, starfish, and hermit crabs. The tanks contain 140 marine animals, mainly fish of the Northeast and Middle Atlantic waters. There are also displays about marine environments, endangered species, and marine science.
