The 5 Largest Aquariums in the World

This blog was originally published on my marine aquarist website, Visit my website for monthly aquarium and marine life updates.

Aquariums have been fascinating to me since I was a little boy, and I now spend a lot of my free time building and maintaining my own saltwater tanks. I have amassed over 1,500 gallons of tanks since I started this hobby, and I have also acquired a number of rare fishes, corals, and plants. While my collection is quite large for an individual, it is not even comparable to many commercial aquariums, especially the five listed below.

Turkazoo Aquarium

The Turkazoo aquarium opened in 2009, and it was Turkey’s first super aquarium. Turkazoo is actually located inside the Forum Istanbul Shopping Mall, and it contains a rainforest, a flooded forest, and multiple tropical sea zones. There are over 10,000 sea creatures in the aquarium including various types of sharks, rays, and seahorses. You can walk through a tunnel that is over 200 feet long and weaves through the 1.32 million gallon tank.

L’Oceanografic Aquarium

Located inside the City of Arts and Sciences in Valencia, Spain, L’Oceanogra is the largest aquarium tank in Europe. There are over 45,000 different marine animals in the tanks with over 8,000 different species. There are nine underwater towers that are on two levels to represent the diverse marine ecosystems in place. There’s also a 150 food underwater tunnel giving visitors the ability to walk through and explore the 1.85 million gallons of water.

The Okinawa Churaumi Aquarium

The Ocean Expo Park in Japan is home to the Okinawa Churaumi Aquarium and its 1.98 million gallons of water. The aquarium was constructed in 2002, and it features a 24-inch thick acrylic glass panel that measures 27 feet high by 74 feet wide. When the aquarium opened in 2002 the panel was the largest in the world, but it has since been taken over by one of the next two aquariums on this list. Manta rays and whale sharks are on the short list of animal attractions at Churaumi.

Dubai Mall Aquarium

The Dubai Mall is one of the largest malls in the world, and it is only fitting for the mall to house the second largest aquarium in the world. The 2.64 million gallons of water are held back from the public by the largest acrylic panel in the world that’s 30 inch thick, 27 feet high, and 108 feet wide. The tank had a small leak in 2010 that caused mass panic and a complete evacuation of the mall before it could be repaired.

Georgia Aquarium

The Georgia Aquarium is by far the largest aquarium in the world at over 6.3 million gallons. You could pour the water from the three previously mentioned aquariums into this behemoth. When it opened in 2005 it was the only aquarium outside of Asia where you could see whale sharks. There are over 100,000 sea dwelling animals occupying the waters in Georgia.
