Santos Aquarium delivers hours of fun for all ages. Inside are 32 tanks. Half have sea water and the others have fresh water. They replicate the natural habitat of the 4,000 marine creatures on display. The most popular residents are sea lions, sharks, tartaruga-de-pente (hawksbill) sea turtles and Patagonia penguins. The Touch Tank is also very exciting for children. Admirers of world-famous sea-life muralist Robert Wyland will enjoy seeing two of his 400 foot paintings inside.
