Seaside Aquarium, Public aquarium in Seaside, Oregon, United States.
The Seaside Aquarium maintains tanks filled with local marine species including harbor seals, wolf eels, octopuses, and numerous varieties of starfish and crabs.
Built in 1924 as a natatorium with heated saltwater from the Pacific Ocean, the structure transformed into an aquarium in 1937 using the original seawater pipe system.
This facility established the first program for breeding harbor seals in captivity, contributing to marine research and public understanding of coastal wildlife.
Located on the beachfront promenade, the aquarium welcomes visitors every day from 9:00 AM to 5:00 PM, offering opportunities to feed seals and touch tide pool creatures.
The aquarium displayed a fish that survived a trans-Pacific journey inside a boat displaced by the 2011 Tōhoku earthquake and tsunami.
