This historic building was constructed in 1924, originally a saltwater bath house. In 1937, it was rebranded as an aquarium. It is the oldest privately owned aquarium on the West Coast. The aquarium's draw is their colony of seals who have been in captivity for six generations and holds the record for having the oldest seal, Clara, who died at 35 years of age in 1979; wild seals live on average for 15 years. The seals are fed on schedule, but you can pay extra to feed the seals yourself. Other animals include an octopus and several invertebrates - some of which you can pet in the touch tank.
