Discover the Pacific Seas

Wander down
in an ocean of discovery.
Stare eye-to-eye with sharks, turtles and eagle rays. Wander down the ramps - perfect for strollers and wheelchairs - to find pulsing jellies, scuttling crabs, darting tropical fish. Descend into underwater magic.
Through shimmer
into deep blue sea.
Pass through shimmers of light art. Enter the deep blue of Baja Bay, then pledge to protect our ocean under giant glass jellyfish. Here, ocean and imagination meet.
All our art

Aquarists care
It takes dedication to be an aquarist, as well as training and time.
Our aquarists spend hundreds of hours getting to know our animals.
Feeding sharks
Using objects the animals have been trained to recognize, each gets its own portion.
It can take awhile! But the aquarists work patiently until everyone is satisfied.
Water is life
Water in the aquarium is pumped straight up from Puget Sound, filtered and warmed through a complex web of pipes.
After it washes nutrients over our animals, it’s treated and flows back into the Sound – no pollution, no waste.

Protecting the Ocean

It takes all of us.

THE THREAT: Our oceans are beautiful – but they face many threats, from plastic pollution to chemicals, oil, overfishing and acidification. Many of the animals in our aquarium are threatened in the wild.

TAKE ACTION: But we can help – the ocean is in our hands. Find out what you can do by visiting the Waves of Change gallery inside the aquarium, or exploring our Protecting Wildlife pages.
