The Georgia Aquarium's Whale Shark and Its Age

The Georgia Aquarium in Atlanta is home to Trixie, a female whale shark who was born around 1994. That makes her roughly 30 years old as of 2024. Whale sharks in the wild can live 70 years or longer, so Trixie is still in her middle years—she has decades of life ahead of her under the aquarium's care.

Trixie arrived at the Georgia Aquarium in 2006 from Taiwan, where she had been living in another facility. She shares the Ocean Voyager exhibit with three other whale sharks: Ocho, Trixie's mate; and two younger sharks named Taroko and Ike. The Ocean Voyager tank holds 6.3 million gallons of water and is one of the largest aquarium habitats in the world.

Key Takeaways

  • Trixie, the Georgia Aquarium's most well-known whale shark, was born around 1994 and is approximately 30 years old.
  • Whale sharks can live 70 years or longer in the wild, so Trixie is in the middle of her natural lifespan.
  • Trixie arrived at the Georgia Aquarium in 2006 from a facility in Taiwan.
  • The Ocean Voyager exhibit where Trixie lives holds 6.3 million gallons of water and houses four whale sharks total.

What Makes Whale Sharks Live So Long

Whale sharks are the largest fish in the ocean, and their size is connected to their longevity. They grow slowly and reach sexual maturity late in life—usually not until they are 25 to 35 years old. This slow growth pattern is typical of long-lived animals and means that a whale shark's body does not wear out as quickly as smaller fish species.

In the wild, whale sharks face threats from fishing nets, boat strikes, and ocean pollution, which can shorten their lives. In captivity, where Trixie lives, these dangers are removed. The aquarium controls water temperature, provides consistent food, and monitors her health regularly. These conditions allow captive whale sharks to live out more of their natural lifespan.

How the Georgia Aquarium Cares for Whale Sharks

The Ocean Voyager exhibit is designed to mimic the open ocean as closely as possible. The tank is 203 feet long, 84 feet wide, and 37 feet deep—large enough that the whale sharks can swim in patterns similar to those they would follow in nature. The water is kept at 76 degrees Fahrenheit, which matches the tropical and subtropical waters where whale sharks are found.

Trixie and the other whale sharks are fed a mix of foods including fish, squid, and specially formulated pellets. In the wild, whale sharks eat plankton by filtering it through their gills, but in captivity they eat larger food items because the aquarium cannot replicate the massive plankton blooms they would encounter in the ocean. The aquarium's veterinary team monitors each shark's weight, behavior, and overall health throughout the year.

Trixie's Role in Research and Conservation

Whale sharks are listed as vulnerable on the International Union for Conservation of Nature (IUCN) Red List, meaning their population is declining in the wild. By keeping whale sharks like Trixie in captivity, the Georgia Aquarium contributes to research that helps scientists understand the species better. Researchers study Trixie's behavior, reproduction, and health to learn what whale sharks need to survive.

The aquarium also uses Trixie and the other whale sharks to teach visitors about ocean conservation. Millions of people visit the Georgia Aquarium each year, and many see a whale shark for the first time. This direct experience can inspire people to support ocean protection efforts and reduce practices that harm whale sharks in the wild, such as overfishing and pollution.

The Other Whale Sharks at the Georgia Aquarium

Trixie is not the only whale shark at the aquarium. Ocho, a male, arrived in 2006 alongside Trixie and is also around 30 years old. Taroko, a younger female, was born in captivity at the Georgia Aquarium in 2007, making her about 17 years old. Ike, the youngest, was also born at the aquarium and is in his early teens.

The presence of multiple whale sharks of different ages allows researchers to study how the species develops from youth to adulthood. Taroko and Ike represent a new generation of whale sharks born in human care, which provides valuable information about reproduction and early development that is difficult to observe in the wild.

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 general admission tickets as well as special experiences like behind-the-scenes tours and animal encounters, though these vary by season and availability.

If you plan to visit, the best times to see the whale sharks are typically early morning or late afternoon, when the tanks are less crowded and the sharks are often more active. The aquarium's website lists current hours, ticket prices, and any special programs happening during your visit.

Frequently Asked Questions

How big is Trixie compared to other whale sharks?

Trixie is one of the largest whale sharks in captivity, measuring around 35 feet long. In the wild, whale sharks can grow to 40 feet or longer, so Trixie is near the upper end of the size range. Her size reflects her age and the stable conditions of the aquarium, where she has had consistent food and care for nearly two decades.

Can whale sharks reproduce in captivity?

Whale shark reproduction in captivity is extremely rare. The Georgia Aquarium has successfully bred whale sharks, with Taroko being born there in 2007. However, breeding does not happen regularly, and scientists still do not fully understand the conditions that trigger reproduction in whale sharks, even in large facilities.

Why do whale sharks need such a large tank?

Whale sharks are ocean animals that swim long distances in the wild. A large tank allows them to move naturally and exercise their muscles, which supports their physical and mental health. The 6.3-million-gallon Ocean Voyager exhibit is one of the few tanks in the world large enough to house whale sharks responsibly.

What do whale sharks eat in the wild versus in captivity?

In the wild, whale sharks filter-feed on plankton, consuming millions of tiny organisms by swimming through plankton-rich waters with their mouths open. In captivity, they cannot access natural plankton blooms, so the Georgia Aquarium feeds them fish, squid, and pellets instead. This diet keeps them healthy, though it is different from what they would eat in nature.
