The Georgia Aquarium holds four whale sharks as of 2026

The Georgia Aquarium in Atlanta is home to four whale sharks: Trixie, Ralph, Norton, and Echo. These are the largest fish in the world, and the aquarium's whale shark exhibit — called Tropical Diver — is one of the few places in North America where you can see them in person. The tank holds 6.3 million gallons of water and is designed to mimic the warm ocean environments where whale sharks naturally live.

The four sharks at Georgia have lived there for different lengths of time. Trixie and Ralph arrived in 2006 when the aquarium first opened its doors. Norton joined them in 2007, and Echo was added later. Each shark has its own personality and feeding routine, and the aquarium staff tracks their health and growth closely.

Why the Georgia Aquarium keeps whale sharks

Whale sharks are endangered in the wild, and public aquariums play a role in research and education about these animals. The Georgia Aquarium's whale shark program contributes to scientific understanding of their behavior, diet, and health. The aquarium works with other institutions and researchers to share what they learn about keeping these massive fish healthy in captivity.

Seeing whale sharks in person helps visitors understand why ocean conservation matters. The aquarium uses its whale shark exhibit to teach guests about threats to marine life, including overfishing and habitat loss. Many visitors say that watching these gentle giants swim changes how they think about protecting the ocean.

What whale sharks eat and how they grow

Whale sharks are filter feeders, meaning they eat by swimming through the water with their mouths open and straining out tiny organisms called plankton. At the Georgia Aquarium, the four sharks are fed a specialized diet that mimics what they would eat in the ocean. The aquarium staff monitors how much each shark eats and adjusts portions based on the individual animal's size and health.

In the wild, whale sharks can grow to 40 feet long or longer. The sharks at Georgia are smaller than the largest wild whale sharks, but they continue to grow throughout their lives. The aquarium's veterinary team tracks their measurements and weight regularly to make sure they are developing normally.

The Tropical Diver exhibit and tank conditions

The Tropical Diver is one of the largest aquarium exhibits in the world. The tank is 203 feet long, 84 feet wide, and 27 feet deep — large enough to give the whale sharks room to swim naturally. The water is kept at a warm temperature year-round to match the tropical and subtropical waters where whale sharks live in nature.

The exhibit also houses other fish species that share the tank with the whale sharks, including manta rays, sea turtles, and various tropical fish. This mixed-species environment is designed to be as close as possible to a natural reef ecosystem. The aquarium's filtration and life support systems work continuously to keep the water clean and the conditions stable for all the animals living there.

How many visitors see the whale sharks each year

The Georgia Aquarium is one of the most visited aquariums in the United States, and the whale shark exhibit is one of its main attractions. Hundreds of thousands of people visit the Tropical Diver each year to see Trixie, Ralph, Norton, and Echo. The exhibit is designed so visitors can view the sharks from multiple levels and angles, including through a large acrylic window.

The aquarium offers different ways to experience the whale sharks, from general admission viewing to special programs where visitors can learn more about the animals and the aquarium's conservation work. Some visitors book behind-the-scenes tours or educational programs that explain how the aquarium cares for these massive fish.

Changes to the whale shark population over time

The number of whale sharks at the Georgia Aquarium has remained stable at four for several years. In the past, the aquarium has had different numbers — sometimes more, sometimes fewer — as animals have been born, transferred to other facilities, or passed away. The aquarium makes decisions about its whale shark population based on the animals' welfare, available space, and breeding recommendations from other institutions.

Whale sharks breed rarely in captivity, and the Georgia Aquarium has not had successful breeding of its whale sharks. The four sharks currently at the facility represent a long-term commitment to their care and to the research and education that comes from housing them.

Frequently Asked Questions

Can you touch or swim with the whale sharks at Georgia Aquarium?

No. Visitors view the whale sharks from designated areas outside the tank. The aquarium does not offer swimming or touching experiences with the whale sharks. Special behind-the-scenes programs may allow closer observation, but direct contact is not permitted to protect both the animals and visitors.

How long do whale sharks live?

In the wild, whale sharks are thought to live 100 years or more, though exact lifespans are not well documented because they are difficult to study in nature. The whale sharks at Georgia Aquarium are monitored closely, and the aquarium's veterinary team works to keep them healthy throughout their lives.

Are whale sharks dangerous?

Whale sharks are not aggressive toward humans. They are filter feeders that eat plankton and small fish, not large animals. In the wild, whale sharks are generally calm and have been known to tolerate human swimmers nearby, though approaching them is not recommended or permitted in most places.

Why does the Georgia Aquarium have whale sharks if they are endangered?

Public aquariums house endangered animals for research, education, and conservation purposes. The Georgia Aquarium's whale shark program contributes to scientific knowledge about the species and helps raise awareness about ocean conservation. The aquarium works with conservation organizations to support whale shark protection in the wild.
