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.

Baja Diving

In clear, blue Baja Bay, three scuba divers are drifting alongside eagle rays and brightly-colored fish. They’re moving slowly, and unlike most divers in tropical waters, they’re not gazing admiringly at the animals around them. Because these divers are aquarists at Point Defiance Zoo & Aquarium – and they’re hard at work. “We clean, we … Continued
