Marine Mammals

Meet our delightful otters and seals!

These exhibits, some of our most popular and   action-packed, are home to a fabulous assortment of charming and entertaining marine mammals. Plan to stay for a while as you get to know our gregarious sea otters, river otters, harbor seals and fur seals—and learn how to tell the difference between them all! 

Choose your view—you can watch animals swimming and diving underwater, on the surface from a spot at the edge of the exhibit, or from a comfortable perch in our seating areas. No matter where you are, you’ll be entranced by the antics of these wonderful creatures as they play, eat, groom, lounge, interact and more. And if you time it right, you can enjoy one of our daily talks and animal feedings.

Don't miss our harbor seal exhibit. With plenty of dry resting area (or haul-out space), a spacious pool, acrylic viewing panels on three sides, and seating for up to 100 visitors, you're sure to get a prime view of Barney, Q and Hogan.

While you’re here, learn about the Seattle Aquarium’s long history with marine mammals. Our research and work impacts not only the animals in our care, but captive and wild populations around the globe as well. We are proud to have the distinction of being the first facility in the world to have a sea otter conceived and born in captivity—and subsequently live to adulthood. We are actively involved in captive fur seal breeding efforts, and were the first to have a northern fur seal conceived and born in captivity.

Each fall, salmon make their way from the open ocean to freshwater—most often, the streams in which they were born—to spawn. It’s an amazing journey…
