Undoubtedly, one of the highlights of the Aquarium of San Sebastian lies in its over 31 aquariums dedicated to the Cantabrian-Atlantic Sea and tropical themed aquariums.
Noteworthy among these, the large tank, we call Oceanarium, crossed by a 360º tunnel, where you can observe a variety of Atlantic and Cantabrian species and the two sand tiger shark.
But besides the doubtless attraction of this tank, with more than 1.5 million liters of water and more than 40 species of fish, you can enjoy a journey full of aquariums where you can contemplate marvelous invertebrates and many more species that provide the proper measure of the biodiversity that hosts the ocean and the importance of preserving it.
