The Seaside Aquarium is a family favorite with it near 100 species of marine life, and it's also one of the oldest aquariums on the West Coast. It established the first program to breed harbor seals in captivity and allows visitors the chance to feed the popular seal family. The aquarium’s Discovery Center features microscopes to view their tiniest creatures and an expert staff to answer questions. Guests can get up close and personal with ornately colored sea anemones, starfish and sea urchins in the Touch Tank. An underwater exhibit displays a constant parade of giant octopus, wolf eels, flatfish, crawling crustaceans, plant-like animals and more – all part of the Pacific's amazing ecosystem.

The aquarium was founded in 1937 and its location has quite the notable history. The marine museum’s building was constructed in 1924. Originally it was a salt water bath house and swimming pool known as the Seaside Baths Natatorium. The baths and pools were filled with water pumped from the Pacific Ocean through a pipe still visible today at tide line and currently used to fill the aquarium’s tanks.  

The Seaside Baths Natatorium has since closed and underwent major renovations to reopen as the Seaside Aquarium. In 1938 apartments were added upstairs but are no longer in use. Nope, it’s just sea dwellers currently calling the Seaside Aquarium home, but they readily welcome human visitors throughout the year.
