It has seven aquariums that replicate the seas. You can learn everything about them here.

Tropical Aquarium

Tropical Aquarium

Tropical shark species can be found in the world’s largest pool of tropical aquariums. 

Some live on coral reefs, while others hunt for food in the open sea.

The water temperature ranges from 23 to 27 degrees Celsius, substantially higher than the Mediterranean basin.

The pool is spectacular, with tropical poison fish and aggressively attacking fish.

Another pool is dedicated to the vibrant diversity of tropical coral reefs, notably the Great Barrier Reef off the coast of Australia.

The residents, which can be found in the Red and Caribbean Seas, may be seen in two basins.

Explora! Children’s Area Barcelona 


Explora! is an interactive room within L’Aquàrium de Barcelona to educate youngsters about the marine world. 

It includes over 50 activities that allow children to touch, see, hear, examine, and discover nature. 

Children will undoubtedly be fascinated by the intriguing underwater world. 

Visitors can access this area by purchasing entry tickets to the Barcelona Aquarium

The inhabitants of the oceans and their ecosystems are introduced to youngsters. It is exciting and engaging for children in a play area.

Three Mediterranean coastline habitats are represented in Explora! – the Ebro Delta wetlands, a section in the Costa Brava and exploring an underwater cave in the Medes Islands. 

The Costa Brava

The coastline that stretches from just outside of Barcelona to the French border is known as the Costa Brava. 

It is distinguished by adorable little towns and villages, rocky, steep peaks, and breathtaking beaches, bays, and inlets.

Discover the Costa Brava’s marshes and beaches in this Explora! section, where you can feel the waves crash over you without getting wet.

The Medes Islands’ Underwater Cave

Explore the reef and the ruins of a shipwreck in this marine reserve off the coast of Catalonia—site of refuge for numerous creatures.

The Medes Islands are a tiny group of rocky outcrops that are situated near the coast of Spain’s Costa Brava. 

They are just across from the resort town and fishing village of L’Estartit. 

The Oceanarium


The Oceanarium is the largest aquarium basin inside the Barcelona Aquarium, with a diameter of 36 meters, a depth of almost 5 meters, and a volume of nearly 4 million liters.

You can find sea bream, moray eels, sunfish, rays, and two shark species, sand tiger sharks (Carcharias taurus) and sandbank sharks (Carcharhinus plumbeus) here. 

Enjoy strolling through this 80-meter-long translucent water tunnel and view the stars of L’Aquàrium. 

In the translucent tube on the “seabed,” you may get up close and personal with sharks and other curious sea creatures.

The Mediterranean

An example of the Mediterranean Sea in miniature is the Oceanarium.

Visit the Oceanarium and have the thrilling sensation of exploring the Mediterranean as though you were walking along the seafloor – only centimeters away from sharks and other marine creatures. 

In the Oceanarium, you may also find the following typical marine organisms:

Planeta Aqua

Planeta Aqua

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

The journey to the Planeta Aqua continues on the second floor after the enormous and stunning oceanariums.

With Barcelona Aquarium tickets, you can experience many diverse organisms adapted to different aquatic environments.

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

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

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

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.

The Tropical Universe

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 can discover specific ecosystems. mangrove swamps with their maze of roots, where the young marine fish take shelter and feed. 

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

The world of darkness

Discover unique forms of existence and stroll through the marine cosmos of Planeta Aqua.

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

Current Research

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

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

The Mediterranean Aquariums

The Mediterranean Aquariums

The L’Aquàrium de Barcelona is the world’s largest aquarium dedicated to the Mediterranean. 

The Mediterranean’s most diverse residents from the most varied locations are found in 14 pools ranging from 6 to 120 m3.

Get your Barcelona Aquarium ticket, watch the animals in their natural habitat, and admire the local fauna!

The Mediterranean Sea, with a length of 3,800 kilometers, a maximum width of 800 kilometers, and an average depth of 1,500 meters, is one of the world’s most perfect marginal seas. 

Despite being a nutrient-poor (oligotrophic) sea, it supports various ecosystems and species. 

One of the most notable is a significant predator – the shark. 

The Strait of Gibraltar connects it to the Atlantic Ocean, and the Bosporus connects it to the Black Sea.

Because of the limited size of its basin and its short connection with the Atlantic, its tides have a very modest amplitude (about 25 cm), giving the sea its distinct aspect. 

The Oceanarium in the Barcelona Aquarium is a miniature representation of the Mediterranean Sea.

Take advantage of the Ebro Delta and the Medes Islands, two recreations of Spain’s coastline.

Ebro Delta

Ebro Delta

Freshwater and saltwater mix in the delta’s coastal lagoons, resulting in a habitat with unique properties.

The Ebro Delta, located in Catalonia’s extreme southeast, stretches for approximately 350 km2. 

This area is designated as a nature preserve as it provides a unique environment for marine species and occasionally visiting migratory sea birds.

It is an intermediate stage between freshwater (from the river Ebro) and seawater, where the first progressively mixes with the second as it flows out into the sea, lowering salinity. 

This results in a succession of intermediate, variable saline conditions that are not conducive to the survival of the various creatures that reside there. 

Because of good management of internal fluids, the many species that reside there can endure relatively high falls and elevations in salt. 

Themed Aquarium

Themed Aquarium barcelona

The themed aquariums in Aquarium Barcelona have small tanks that allow visitors to see little animals. 

The themed aquariums in Aquarium Barcelona include marine invertebrates (sea urchins and starfish), seahorses, tropical corals, and sea dragons.

Different themed aquariums in Aquarium Barcelona are as follows –

  • Marine invertebrates
  • Seahorses
  • Shark Eggs
  • Tropical Corals
  • Amazing underwater creatures

Marine invertebrates

To better comprehend this group of marine animals, this tank displays some representatives of the various species of invertebrates. 

Sharpen your vision to distinguish some hermit crabs and shrimp in this neighborhood.

Shark eggs

You may want to look closely at the shark eggs in the aquarium, hanging between the corals and marine plants.

Shark eggs have a lengthy and relatively translucent shell that allows you to observe how the shark embryos develop inside. 

Look closely at the eggs because the embryos may be moving within the tank at the bottom because some have already been born.

Tropical corals

Tropical corals

Corals are colonies of microscopic animals known as polyps that construct intricate reef structures. They are genuinely natural architects.

In this tiny aquarium, you can see several beautiful corals up close and how polyps move by opening and shutting their tentacles.

This tank’s coral have been bred in captivity without removing specimens from the wild.

Amazing underwater creatures

In these little aquariums, you can see marine species with unusual shapes that resemble mythological beings. 

They can take on bizarre shapes to adapt to their surroundings. They will pique your interest and take you to a world of myth and legend.

They are currently home to clownfish and leafy seadragons, a type of seahorse that is difficult to identify from its surroundings.
