Aquário de Ubatuba, Public aquarium in Ubatuba, Brazil.

The Aquário de Ubatuba is a private aquarium opened in February 1996, with 21 tanks holding 110 species and 430 animals. Its tanks are mostly medium-sized plus one large one, and freshwater and saltwater organisms are grouped by taxonomy. One space recreates ecosystems such as mangroves and coral reefs, and a highlight is a nurse shark recovered from a private owner.

The facility was founded in 1996 and was Brazil's first private aquarium opened to the general public. Since opening, it has grown into an important place for marine research and visitor experiences.

The aquarium plays an important role in environmental education, showing how the ocean and its creatures matter to people's lives. Many school groups visit to experience marine life directly and learn about protecting the ocean.

The aquarium has 21 tanks, mostly medium-sized plus one large tank, arranged by species taxonomy and by ecosystems such as mangroves and coral reefs. Allow time to see both the freshwater and saltwater displays. The Praça da Baleia, with the skeleton of a humpback whale that stranded on Praia Grande in the early 2000s, is an important reference point in the area.

The Praça da Baleia, an outdoor square linked to the aquarium, holds the skeleton of a humpback whale that stranded on Praia Grande in the early 2000s. In 2009 the aquarium and the city council recovered and restored the bones, which now form the centrepiece of the square.
