Our seals welcome all visitors to the Long Island Aquarium! Located right outside the main entrance, the 800-square foot natural rockscape pool provides a home to our harbor seals (Phoca vitulina) and our gray seal (Halichoerus grypus).

Unlike sea lions, harbor seals and gray seals are true seals. They lack the ear flaps that sea lions have, but they are just as beautiful! They spend much of their day either lying around on the shorelines or hunting for fish and marine invertebrates in the sea.

The Long Island Aquarium’s gray seal, Gray Beauty, has a particularly compelling story. She was rescued by the Riverhead Foundation for Marine Research and Preservation. Despite her blindness from cataracts, Gray Beauty was patiently nurtured at the Long Island Aquarium until she was able to comfortably navigate the exhibit on her own.

The Aquarium’s Marine Mammal trainers work with our seals throughout the day. You can stop by anytime to watch the seals perform a variety of training behaviors or you can simply watch them play! Don’t miss the Seal Training & Feed Session each day at 11:30am.
