Planeta Aqua

Buy This Tickets

Water covers over three-quarters of our globe. Despite this, we know less about the oceans and their inhabitants than we do about the Moon’s surface. 

The journey continues on the second floor after visiting our enormous and stunning oceanariums.

Planeta Aqua will assist you in discovering many of the organisms that have adapted to the most different aquatic environments: brutal cold, deep darkness, and warm tropical waters. 

You can also see how different varieties of rays, such as freshwater stingrays and eagle rays, swim thanks to a 20,000-liter open tank.

On Planeta Aqua’s circular mezzanine Floor, you may see living fossils and learn about phenomena like camouflage, symbiosis, oceanographic secrets, and environmental challenges. 

Through computer games, information panels, small aquariums, and interactive features, you can learn about the evolution of various mammals, reptiles, and fish adapted to the marine environment.

Life in the cold

A newly designed enclosure that matches the natural climatic conditions of Humboldt penguin habitats allows you to watch these animals while swimming underwater.

To enable them to swim, their wings have been converted into fins. Their thick fat layers protect them from the cold and deflect water. 

Moreover, they have a thick coat of feathers that allows them to retain warm air from their body heat. 

They can blend in with the sunlight or the blackness of the bed when they are in the water thanks to their camouflage mechanism, which is why they have dark backs and light bellies. 

While adults have white bellies with an arched black line, juvenile Humboldt penguins have silvery bellies. 

They consume plankton-containing fish, squid, and tiny crustaceans as food. The Humboldt penguins swim about 45 km/h and descend to depths of 70 m. 

About the Humboldt penguins:

Length65 cm 
Feeding Time11.30 am to 4.30 pm
FactsHumboldt penguins typically swim at an average speed of 4.5 km/h. They usually dive underwater for about 20 seconds before resurfacing, alternating between swimming below and on the surface.

The Tropical Universe

Planeta Aqua has also replicated the three main sections of a tropical river: the upper, middle, and lower courses. 

At the mouths of these tropical rivers, we discover specific ecosystems: mangrove swamps with their maze of roots, where the young of many marine fish take shelter and feed. 

You’ll be able to observe exotic species, including piranhas, tropical turtles, and iguanas, here.

The World Of Darkness

Planeta Aqua invites you to stroll through the immensity of the marine cosmos and discover various unique forms of existence.

Ranging from living animals such as jellyfish that drift around in places still reachable by light to others that have adapted to the extreme pressures of the deep.

Current Research

This section informs you about the history of conquering and ocean knowledge and how much remains to be found. 

You can discover how various oceanographic equipment functions and see what a submarine’s inside looks like in the bathyscaphe.
