This 4½-acre complex brings visitors face to face with the creatures living in offshore and near-shore Pacific marine habitats: Flirting, frolicking sea otters, colorful puffins, pulsating jellyfish, and even a 60-pound octopus. There's a hands-on interactive area for children, including tide pools perfect for "petting" sea anemones and urchins. The aquarium houses one of North America's largest seabird aviaries, including glowering turkey vultures. Permanent exhibits include Passages of the Deep, where visitors walk through a 200-foot underwater tunnel with 360-degree views of sharks, wolf eels, halibut, and a truly captivating array of sea life. Large coho salmon and sturgeon can be viewed in a naturalistic setting through a window wall 9-feet high and 20-feet wide. The sherbet-colored nettles are hypnotizing.
