The Aquarium of the Bay first opened its doors on April 19, 1996, initially known as "UnderWater World." Constructed at a cost of US$38 million, it began by showcasing approximately 4,000 fish representing 100 unique species indigenous to the San Francisco Bay. Since 2005, the aquarium has significantly evolved its mission, placing a strong emphasis on ocean conservation and climate action, both locally and globally. A notable addition to its offerings was the North American river otter exhibit, which opened on June 28, 2013, quickly becoming a beloved feature.

During the winter, "Otter Snow Days" feature snow in the river otter enclosure, adding a unique element to their habitat. The nearby Sea Lion Center at Pier 39 is also active in winter, when large numbers of sea lions gather on the docks.
