The Georgia Aquarium holds four whale sharks
The Georgia Aquarium in Atlanta is home to four whale sharks: Trixie, Ralph, Norton, and Alice. These are the only whale sharks on display in the United States. The aquarium opened its Beluga-Whale Shark exhibit in 2005 with two whale sharks, and the population grew to four over the following years.
Whale sharks are the world's largest fish species. They can grow to 40 feet long or more and weigh as much as 20 tons. Despite their enormous size, they eat only plankton and small fish, filtering food through their gills as they swim. The Georgia Aquarium's whale sharks live in a tank called Ocean Voyager, which holds 6.3 million gallons of water—one of the largest aquarium habitats in the world.
Key Takeaways
- The Georgia Aquarium houses four whale sharks: Trixie, Ralph, Norton, and Alice, making it the only facility in the United States with whale sharks on display.
- Whale sharks are the largest fish species in the world, reaching lengths of 40 feet or more and weighing up to 20 tons.
- The whale sharks live in the Ocean Voyager exhibit, a 6.3-million-gallon tank designed to accommodate their size and swimming behavior.
- The aquarium's whale shark population has remained stable at four individuals since the exhibit expanded beyond its original two sharks.
Why the Georgia Aquarium has whale sharks
The Georgia Aquarium built its whale shark exhibit as part of a broader mission to house and study large marine animals. Whale sharks do not breed well in captivity, so the four at the Georgia Aquarium were all captured from the wild—a practice that would not be permitted under current conservation standards. The aquarium has kept these animals for nearly two decades because moving them or releasing them would likely harm them.
The presence of whale sharks draws visitors from around the world and funds the aquarium's research and conservation work. Scientists at the facility study whale shark behavior, health, and nutrition to better understand the species in its natural habitat. This research has contributed to what marine biologists know about whale shark migration patterns and feeding habits.
The Ocean Voyager tank and its design
Ocean Voyager is not a single tank but a system of interconnected pools. The main viewing area holds 6.3 million gallons and is 100 feet long, 78 feet wide, and 30 feet deep. The tank also includes a separate area where the whale sharks can be isolated if one needs medical care or if the group needs to be separated for any reason.
The water in the tank is kept at a temperature between 72 and 78 degrees Fahrenheit, which mimics the warm tropical waters where whale sharks live in nature. The aquarium uses a sophisticated filtration system to keep the water clean and maintain the right balance of salt and minerals. The tank is also home to thousands of other fish, including manta rays, groupers, and jacks, which share the space with the whale sharks.
How the whale sharks are fed
The Georgia Aquarium's whale sharks are fed a diet of fish eggs, fish larvae, and small fish. In the wild, whale sharks eat plankton by filtering water through their gills, but this feeding method is not practical in captivity. Instead, the aquarium's staff places food directly into the tank, and the whale sharks consume it by swimming through the water with their mouths open.
Each whale shark eats several pounds of food per day. The aquarium's nutritionists work to may support that the diet provides all the vitamins and minerals the sharks need to stay healthy. Feeding time is also an opportunity for staff to observe the sharks' behavior and check for any signs of illness or injury.
The individual whale sharks at the Georgia Aquarium
Trixie and Ralph were the first two whale sharks to arrive at the Georgia Aquarium in 2005. Trixie is female and Ralph is male. Norton and Alice joined them later, expanding the group to four. Each shark has a distinct personality and swimming pattern, which allows staff members to identify them by sight.
The sharks vary in size, with some being noticeably larger than others. Age differences account for some of this variation—younger sharks are smaller than older ones. The aquarium tracks each shark's growth, health, and behavior over time to monitor their well-being and adjust care as needed.
Conservation and the future of whale sharks in captivity
Whale sharks are listed as vulnerable by the International Union for Conservation of Nature, meaning their wild populations face threats from fishing, pollution, and climate change. The Georgia Aquarium's whale sharks cannot be returned to the wild because they have spent most or all of their lives in captivity and would not survive on their own.
The aquarium does not plan to breed its whale sharks, partly because breeding in captivity is extremely difficult and partly because conservation experts believe resources are better spent protecting wild populations. Instead, the facility focuses on research, education, and public awareness about whale shark conservation. Visitors who see the whale sharks often become more interested in ocean conservation and marine life protection.
Visiting the whale sharks at the Georgia Aquarium
The Georgia Aquarium is located in downtown Atlanta and is open year-round. The Ocean Voyager exhibit is one of the main attractions, and visitors can view the whale sharks from multiple levels and angles. The aquarium offers both general admission and special experiences like behind-the-scenes tours and interactive programs where visitors can learn more about the sharks and the aquarium's work.
Peak visiting times are typically weekends and school holidays. If you want a less crowded experience, weekday visits during the school year tend to be quieter. The aquarium's website provides current hours, admission prices, and information about special programs or exhibits.
Frequently Asked Questions
Can you touch the whale sharks at the Georgia Aquarium?
No, visitors cannot touch the whale sharks. They view them from behind glass or from designated viewing areas. The separation protects both the sharks and the visitors. Some special programs allow visitors to get closer to other animals in the aquarium, but whale sharks are not included in these experiences.
Are the whale sharks at the Georgia Aquarium endangered?
Whale sharks as a species are listed as vulnerable, not endangered, but their populations are declining in the wild. The four sharks at the Georgia Aquarium are healthy and well-cared-for, but they represent a tiny fraction of the global whale shark population.
How long do whale sharks live?
In the wild, whale sharks are believed to live 100 to 150 years or more, though exact lifespans are difficult to determine because they live so long. The whale sharks at the Georgia Aquarium have lived in captivity for nearly two decades and show no signs of age-related decline.
Why doesn't the Georgia Aquarium have baby whale sharks?
Whale sharks rarely breed in captivity, and breeding them would require resources and space that the aquarium dedicates to research and conservation instead. The four sharks at the facility are all adults, and the aquarium has no plans to attempt breeding.
How much does it cost to see the whale sharks?
General admission to the Georgia Aquarium includes access to the Ocean Voyager exhibit where the whale sharks live. Admission prices vary by age and whether you purchase tickets online or at the gate. Check the aquarium's website for current pricing and any special offers.
