Planeta Aqua

Nearly three quarters of our planet is covered with water. In spite of this, we know less about the oceans and their inhabitants than we do about the surface of the Moon.

After visiting our large aquariums and spectacular Oceanarium, the tour continues on the second floor. Planeta Aqua will help you discover many of the creatures that have adapted to the most diverse of aquatic environments: the bitter cold, the darkness of the deep, warm tropical waters. You can also admire the way different types of ray, such as freshwater stingrays and eagle rays, swim, thanks to an open tank containing 20,000 litres of water.

On Planeta Aqua’s circular mezzanine floor, you can observe living fossils and find out about phenomena such as camouflage, symbiosis, some secrets of oceanography and environmental issues. Through computer games, information panels, small aquariums and interactive elements, you can learn about the evolution of different mammals, reptiles and fish, which have all adapted to the marine environment.


A specially-designed enclosure that replicates the natural climatic conditions of regions inhabited by the Humboldt penguin enables you to observe these animals even when swimming underwater.

Pingüinos Aquarium


In Planeta Aqua, we have also recreated the three main sections of a tropical river: the upper, middle and lower courses. At the mouth of these tropical rivers, we find particular ecosystems: mangrove swamps with their maze of roots where the young of many marine fish take shelter and feed. Here, you’ll have the opportunity to see certain exotic species, such as piranhas, tropical turtles and iguanas.

Planeta Aqua L'Aquàrium


In this life-size sperm whale recreation, Planeta Aqua invites you to walk through the vastness of the marine universe and discover other remarkable ways of life, ranging from living organisms that drift around in areas still reached by light, such as jellyfish, to others that have adapted to the high pressures of the deep.

Medusas L'Aquàrium de Barcelona


This corner enables you to find out about the history of the conquest and knowledge of the oceans, and also how much still remains to be discovered. In the bathyscaphe, you can learn how some oceanographic instruments work and see what the inside of a submarine looks like.
