The Aquariums That House Whale Sharks

Only a handful of aquariums in the world keep whale sharks, because these fish are enormous, require specific water conditions, and are difficult to breed in captivity. The Georgia Aquarium in Atlanta holds the most whale sharks of any facility — four animals in its Ocean Voyager exhibit, the largest indoor tank in the United States. The Okinawa Churaumi Aquarium in Japan displays two whale sharks in its Kuroshio Sea tank, one of the largest acrylic panels in the world. The Dubai Aquarium & Underwater Zoo in the United Arab Emirates houses one whale shark in its main tank. These three facilities represent the vast majority of whale sharks on public display.

Each aquarium took years to prepare its exhibits before bringing in whale sharks. The fish need tanks with millions of gallons of water, precise temperature control, and constant food supplies — whale sharks eat plankton and small fish, requiring staff to maintain live feeding systems. Most aquariums that attempted to keep whale sharks in the past have since released them back to the ocean or closed their programs because the cost and complexity became unsustainable.

Key Takeaways

  • The Georgia Aquarium in Atlanta has the largest collection of whale sharks in captivity, with four animals in a single massive tank.
  • The Okinawa Churaumi Aquarium in Japan and the Dubai Aquarium each house one or two whale sharks and are among the few facilities worldwide with these animals.
  • Whale sharks require enormous tanks with millions of gallons of water and specialized feeding systems, which is why so few aquariums can support them.
  • Most whale sharks on display were caught in the wild or bred in facilities with existing populations, and breeding in captivity remains extremely rare.

The Georgia Aquarium's Ocean Voyager Exhibit

The Georgia Aquarium opened in 2005 with four whale sharks — Trixie, Ralph, Norton, and Alice — all caught in the wild off the coast of Western Australia. The Ocean Voyager tank holds 6.3 million gallons of saltwater and is 209 feet long, 78 feet wide, and 33 feet deep. The tank also contains manta rays, sea turtles, and thousands of smaller fish, creating a mixed-species environment that mimics open ocean conditions.

The aquarium maintains the water temperature at 72 to 78 degrees Fahrenheit and filters the entire tank multiple times per day. Staff feed the whale sharks a mixture of live fish and plankton-based supplements several times daily. The facility employs a dedicated team of marine biologists and veterinarians who monitor the sharks' health through regular observations and blood tests. Visitors can view the tank from multiple levels, including an underwater acrylic tunnel that allows face-to-face viewing of the sharks as they swim overhead.

The Okinawa Churaumi Aquarium's Kuroshio Sea Tank

The Okinawa Churaumi Aquarium in Japan opened its Kuroshio Sea exhibit in 2002 with two whale sharks, Chura and Kailani. The tank holds 7.5 million gallons of water and features one of the world's largest acrylic panels — 22.5 meters wide, 8.2 meters tall, and 60 centimeters thick. The panel is so large that it bends slightly under water pressure, and the aquarium had to develop custom acrylic formulations to prevent cracking.

The Kuroshio Sea tank also houses manta rays, sea turtles, and large schools of trevally and other fish. The water temperature is maintained between 72 and 77 degrees Fahrenheit. The aquarium sources live plankton and small fish from local waters and supplements the whale sharks' diet with specially prepared food. The facility is located on the island of Okinawa and draws visitors from across Japan and Asia.

The Dubai Aquarium's Main Tank

The Dubai Aquarium & Underwater Zoo, located inside the Dubai Mall, houses one whale shark in its main tank alongside sawfish, groupers, and rays. The main tank holds 10 million gallons of water and is one of the largest single-panel acrylic tanks in the world. The whale shark shares the space with hundreds of other species, making it one of the most biodiverse exhibits housing a whale shark.

The facility maintains strict water quality standards and employs a large team of aquarists and marine specialists. The tank is viewable from multiple angles, including through the main acrylic panel and from an underwater tunnel. The Dubai Aquarium is a major tourist attraction in the United Arab Emirates and receives millions of visitors annually.

Why So Few Aquariums Keep Whale Sharks

Whale sharks are the world's largest fish, reaching lengths of 40 feet or more and weighing up to 20 tons. Building a tank large enough to house them requires enormous capital investment — the Georgia Aquarium cost over $250 million to construct, with a significant portion dedicated to the Ocean Voyager exhibit. The ongoing operational costs are equally steep: feeding, water treatment, and specialized veterinary care run into millions of dollars annually.

Breeding whale sharks in captivity has proven nearly impossible. The Georgia Aquarium has never successfully bred its whale sharks, and no other facility has either. Scientists do not fully understand the reproductive triggers for whale sharks in the wild, making it difficult to create the conditions necessary for breeding in tanks. This means that any whale shark in an aquarium was caught from the ocean, raising ethical concerns about removing these animals from their natural habitat.

Several aquariums have closed their whale shark programs over the past two decades. The Monterey Bay Aquarium in California, which housed a whale shark from 2007 to 2012, released its animal back to the Pacific Ocean after determining that long-term captivity was not sustainable. The decision reflected growing scientific consensus that whale sharks do not thrive in confined spaces and that the resources required to keep them could be better spent on ocean conservation.

What to Expect When Visiting a Whale Shark Exhibit

If you visit an aquarium with a whale shark, expect to see a massive, slow-moving fish with a distinctive spotted pattern on its body. Whale sharks are filter feeders and spend most of their time swimming with their mouths open, taking in water and plankton. They are generally docile and show little interest in humans, though they may approach viewing areas out of curiosity.

Most whale shark exhibits are designed to allow viewing from multiple angles — above the water, at water level, and sometimes from underwater tunnels. The tanks are large enough that the sharks have room to swim, though marine biologists debate whether captive tanks can ever truly replicate the open ocean environment. Visiting times and viewing areas vary by facility, so check the aquarium's website before your visit for current information about hours and any temporary closures.

Conservation and the Future of Whale Sharks in Captivity

The future of whale sharks in aquariums remains uncertain. Conservation organizations increasingly argue that resources should focus on protecting whale sharks in the wild rather than maintaining small captive populations. The International Union for Conservation of Nature lists whale sharks as vulnerable, meaning their populations are declining due to fishing, ship strikes, and habitat loss.

Some aquariums are shifting their approach by funding ocean research and marine protected areas instead of maintaining large captive collections. The Georgia Aquarium, for example, supports whale shark research programs in Mexico, the Maldives, and other regions where the fish are found in the wild. These programs track migration patterns, study breeding behavior, and work with local communities to reduce threats to wild populations.

Frequently Asked Questions

Can whale sharks breed in aquariums?

No aquarium has successfully bred whale sharks in captivity. Scientists do not fully understand what triggers reproduction in the wild, making it extremely difficult to create the right conditions in a tank. All whale sharks currently in aquariums were caught from the ocean.

How long do whale sharks live in aquariums?

Whale sharks in aquariums typically live 10 to 20 years, though some have lived longer. The oldest whale shark on record in captivity is Trixie at the Georgia Aquarium, who has been there since 2005. Lifespan in the wild is estimated at 100 to 150 years, suggesting that captivity may shorten their lives.

Are whale sharks dangerous to other fish in the tank?

Whale sharks are filter feeders and eat only plankton and small fish. They do not hunt large fish and generally coexist peacefully with other species in mixed tanks. Manta rays, sea turtles, and groupers commonly share exhibits with whale sharks without conflict.

How much does it cost to visit a whale shark aquarium?

Admission prices vary by facility. The Georgia Aquarium charges between $30 and $45 for general admission, depending on the season. The Okinawa Churaumi Aquarium charges around $25 to $30. The Dubai Aquarium charges approximately $30 to $35. Check each facility's website for current pricing and any discounts.

What do aquariums feed whale sharks?

Whale sharks are fed a combination of live plankton, small fish, and specially formulated supplements. Aquariums source live food from local waters or breed it in-house. Staff feed the sharks multiple times per day to meet their nutritional needs, which can be challenging because whale sharks naturally consume vast quantities of plankton in the ocean.
