    Love Ocean Animals? Support Our Animal Care Center

    We're expanding our Animal Care Center to better meet the needs of ocean animals at the Aquarium and in the wild.

Look into a mysterious, mesmerizing world where life looms large.

You'll see giant tuna power their way through the water, while pelagic rays and green sea turtles swim just inches away.

The stunning one-million-gallon Open Sea exhibit is home to one of the most diverse communities of open-ocean animals to be found in any aquarium.

We recently added 5,000 new Pacific sardines to our Open Sea exhibit! Like synchronized swimmers, sardines in a school move together as one. When predators come near, there's safety in numbers for these small fish.

Discover the Ocean's Past

To protect the ocean today, we must learn about its past health, and how ecosystems are changing. Scientists at our new Ocean Memory Lab are analyzing the tissues of long-dead sea creatures to unlock stored secrets about ocean dynamics dating back a century or more.

Revealing Tuna Secrets

Our Tuna Research and Conservation Center, a partnership with Stanford University, is achieving unprecedented insight into the lives of bluefin tuna.
