Chimelong Ocean Kingdom, The Largest Aquarium In The World, Holds 48.7 Million Liters Of Water, Houses Whale Sharks, And Features The Largest Glass Panel Ever Built.
Located in Zhuhai, Guangdong Province, southern China, is one of the greatest feats of aquatic engineering and architecture ever achieved: the Chimelong Ocean Kingdom. Opened in 2014, the theme park quickly made history by securing five Guinness World Records, including that of the largest aquarium in the world, thanks to a colossal structure that holds 48.75 million liters of saltwater distributed among giant tanks.
The space is not just an amusement park, but a scientific, tourist, and architectural complex capable of simulating marine ecosystems on a monumental scale. Its construction cost over US$ 2 billion and transformed the city of Zhuhai into an international destination for marine life enthusiasts, scientists, and engineers interested in the challenges of recreating an ocean within concrete and glass walls.
Colossal Dimensions That Challenge The Imagination
To understand the grandeur of Chimelong Ocean Kingdom, just analyze a few numbers:
-
With over 14 million baskets of earth moved, an ancient North American metropolis built a monumental pyramid of 30 meters and established a city with 20,000 inhabitants nearly a thousand years ago.
-
A 1,900-year-old treasure emerges from a Roman house destroyed by fire and sealed since antiquity in Romania, with coins and metals fused among the ashes.
-
The Brazilian colonial city that stopped in time and shares territory with a rocket launch base.
-
79-year-old woman challenges limits, visits 193 countries in the world after 56 years of planning and reveals the behind-the-scenes of a global journey that few have managed to accomplish.
- 48.75 million liters of water circulate in the tanks, enough to fill almost 20 Olympic-sized swimming pools.
- The main tank alone contains 22.7 million liters of water.
- The largest acrylic panel in the world measures 39.6 meters in length by 8.3 meters in height, with a thickness of 65 cm, allowing visitors to observe the giant tank as if they were looking at an ocean wall.
- The park hosts whale sharks, the largest fish on the planet, as well as giant rays, dolphins, and hundreds of rare species.
These figures explain why the Guinness World Records recognized the structure as the largest ever built to recreate marine life.
The Engineering Behind The Glass Giant
Building the largest aquarium in the world required a combination of science, technology, and architectural boldness.
The glass panel, for instance, needed to be designed in layers of acrylic capable of withstanding pressures equivalent to hundreds of tons of water.
The water filtration and quality control system is also impressive: thousands of pumps, sensors, and filters work continuously to maintain the ideal conditions of salinity, temperature, and oxygen.
The goal is to ensure the well-being of the animals and prevent imbalances in an artificially recreated ecosystem.
Engineers explain that the challenge was not only to erect the physical structure but also to simulate ocean behavior in terms of internal currents, natural lighting, and the animals’ food cycles.
Whale Sharks: Stars Of An Artificial Sea
Among the hundreds of species present, the absolute highlight is the whale sharks, fish that can exceed 12 meters in length and weigh over 20 tons.
Rare in aquariums due to their colossal size, they make Chimelong one of the few places in the world where it is possible to observe them up close in a controlled environment.
The main tank, with its 22.7 million liters of water, was specifically designed to house these giants, ensuring enough space for them to swim freely.
Alongside them swim large manta rays and schools of thousands of fish, creating a visual experience that makes visitors feel like they are literally in the ocean.
Impressive Guinness Records
Chimelong Ocean Kingdom has achieved five world records recognized by the Guinness World Records:
- Largest Volume Of Water In An Aquarium – 48.75 million liters.
- Largest Individual Aquarium Tank – 22.7 million liters.
- Largest Acrylic Panel – 39.6 m x 8.3 m, with 65 cm thickness.
- Largest Underwater Window – with 129 m² of transparent area.
- Largest Observation Dome – structure that allows 360º views inside the aquarium.
These records consolidate the aquarium as not only the largest but also the most advanced in terms of engineering and design for marine life.
Between Science And Spectacle
Although it is known worldwide as a tourist attraction, Chimelong also plays a scientific role.
The park maintains programs for marine biology research and reproduction of endangered species, in addition to working with universities and conservation centers to expand knowledge about sharks, rays, and tropical fish.
The presence of rare species in captivity, however, generates debates. Environmental organizations question the impact of keeping whale sharks in artificial tanks, arguing that their size and migratory habits make them unsuitable for confinement.
Chimelong, in turn, defends that the animals receive veterinary care and controlled nutrition, and serve as ambassadors for marine preservation.
Tourism And Economic Impact
Since its opening in 2014, Chimelong Ocean Kingdom has welcomed millions of visitors per year, becoming one of China’s most popular attractions. Its existence has spurred the development of the city of Zhuhai as a tourist hub, with new hotels, restaurants, and infrastructure to accommodate tourists from all over the world.
The economic impact is estimated at hundreds of millions of dollars annually, consolidating the park as a symbol of the Chinese entertainment industry and its capacity to build megaprojects that unite tourism and spectacle.
The Human Fascination With The Colossal
The grandeur of Chimelong Ocean Kingdom reflects a distinctive characteristic of humanity: the desire to dominate, recreate, and contemplate nature on an epic scale.
Just like skyscrapers and record-breaking bridges, the largest aquarium in the world is an example of how humans seek to push technological limits to approach what once seemed impossible.
But at the same time, it raises a reflection: to what extent does the reproduction of ecosystems in artificial environments solely serve the spectacle, and how far can it contribute to science and environmental preservation?
A Bottled Ocean
With almost 49 million liters of saltwater, Chimelong Ocean Kingdom shows that the largest aquarium in the world is, in practice, a bottled ocean in glass.
Its transparent panel, equivalent to a three-story wall, allows the public to contemplate the grandeur of species that would normally only be seen in deep dives in the seas.
More than numbers, what impresses is the experience: being in front of whale sharks swimming in a tank with millions of liters of water is a feeling that mixes fascination, respect, and even fear.
The Legacy Of The Largest Aquarium In The World
A decade after its inauguration, Chimelong Ocean Kingdom continues to be a global reference in aquatic engineering, tourism, and debate regarding the limits of interaction between humans and nature.
Its title of largest aquarium in the world is not just a matter of numbers, but a landmark in human capability to recreate environments that challenge the imagination.
Just like iceberg B-15 or the fungus Armillaria ostoyae, Chimelong Ocean Kingdom is a reminder that scale can both fascinate and frighten at the same time. It is a man-made ocean — controlled, measured, and framed — yet still a reflection of the force and beauty that only marine life can offer.
