About The Maritime Aquarium

Easy access from I-95 or Metro North Railroad, convenient covered parking next door, warm and spacious with two on-site cafes, gift shop and a 4D Theater, the Aquarium is a most excellent family outing, date or solo visit! The Maritime Aquarium is the only aquarium devoted to Long Island Sound, the “Estuary of National Significance” just outside our doors. As an arm of the Atlantic Ocean, the Sound is an environment rich in aquatic life … even within sight of heavily urbanized New York City.

The marine population we exhibit includes varieties of sharks, big and small, stingrays, harbor seals, sea turtles, game fish, jellies, crabs, lobsters, mollusks and more. We also exhibit tropical travelers that follow the Gulf Stream north to our waters. Plus we have some other fun animals, from tamarins to meerkats. We offer lots of touch experiences including stingrays, sharks, jellyfish and intertidal animals.
