Partly occupying an Art Deco building, this large and particularly impressive aquarium offers a diversified approach to the marine biotope and the special links that Biarritz has with the ocean. It features around twenty tanks home to the fauna found in the Bay of Biscay. Enhanced by a presentation on whale hunting, the Cetacean gallery exhibits skeletons of animals that have been washed up on shore. Visitors can also view seals, sharks (the highlight of the visit), the touch tank, and an exhibit that follows the Gulf Stream.
