Visit San Francisco’s only waterfront aquarium to get up close and personal with the bay’s amazing marine life. Walk through crystal-clear tunnels of water filled with more than 20,000 aquatic animals, including sevengill sharks, the bay’s largest predators. You can touch leopard sharks, rays and sea stars. Daily events include animal feedings and naturalist presentations. Don’t miss the permanent river otter exhibit, where you can watch otters playing, swimming and eating.
