The 100,000-gallon Northern California Coast tank replicates the habitats of the Gulf of the Farallones National Marine Sanctuary. A walkway along the surface allows visitors to smell the seawater and witness the filling and draining of tidepools as waves spill onto a small beach. A large, L-shaped underwater window reveals the eels, anemones, sea stars, rockfish, herring, sardines, and urchins that live beneath the water's surface.
Nearby tanks feature a giant sea bass and a giant Pacific octopus. There's also Discovery Tidepool where visitors can touch and examine a wide variety of ocean creatures.
