Underwater Dome

Be surrounded by Puget Sound's sea life!

Step through a short tunnel and into our one-of-a-kind undersea dome with a 360º view into a 400,000-gallon habitat, filled with hundreds of fascinating Puget Sound fish!

In the Underwater Dome, our largest habitat, you’ll experience a beautiful, ever-changing snapshot of life in Puget Sound. See schools of silvery, open-water salmon flash in the filtered light from above. Large lingcod lurking around underwater reefs with sharks swimming past and brightly colored deep-water rockfish hovering near crevices. Large sturgeon prowling the bottom for leftovers. Skates banking upward against the current. A live, seasonal kelp forest. And more!

Creatures you're likely to see


Some rockfish species can live to be well over 100 years old!

Salmon fry

Seasonally, 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 for an animal that’s critically important in a variety of ways.
