The Georgia Aquarium in Atlanta Holds the Record
The Georgia Aquarium in Atlanta, Georgia, is the largest aquarium in the world by water volume. It opened to the public in 2005 and holds 11.5 million gallons of water across its exhibits. The building itself spans 550,000 square feet, making it not only the biggest by volume but also one of the most physically massive aquarium facilities on Earth.
The aquarium's size allows it to house some of the ocean's largest animals. The facility is most famous for its whale sharks — the largest fish species in the world — which swim in the Oasis tank alongside manta rays and other large marine life. The sheer volume of water needed to keep these massive creatures healthy is what gives the Georgia Aquarium its record-breaking status.
Key Takeaways
- The Georgia Aquarium in Atlanta, Georgia, is the world's largest by water volume at 11.5 million gallons.
- The facility opened in 2005 and covers 550,000 square feet of indoor space.
- The aquarium is home to whale sharks, manta rays, beluga whales, and thousands of other marine species across multiple themed exhibits.
- The Oasis tank is the signature exhibit and requires the most water of any single tank in the facility.
- The aquarium's record has remained unbroken since its opening, though other large facilities have been built worldwide.
How the Georgia Aquarium Compares to Other Large Facilities
Several other aquariums around the world are massive in their own right, but none exceed the Georgia Aquarium's water volume. The Okinawa Churaumi Aquarium in Japan, which opened in 2002, was the largest before Georgia's facility opened. It holds 7.5 million gallons and is still considered one of the most impressive aquariums globally, particularly for its massive main tank and its focus on coral reef ecosystems.
The Shanghai Ocean Aquarium in China and the Monterey Bay Aquarium in California are also among the world's largest and most visited facilities. However, they hold significantly less water than the Georgia Aquarium. The difference in water volume affects what kinds of animals can be housed and how the exhibits are designed. Larger volumes allow for bigger animals and more complex ecosystems to be maintained.
What Animals Live in the Georgia Aquarium
The Georgia Aquarium houses over 100,000 animals representing more than 500 species. The whale sharks are the main attraction — these gentle giants can grow to 40 feet long and weigh as much as a school bus. The aquarium has successfully maintained whale sharks in captivity for extended periods, which was considered difficult before the facility opened.
Beyond the whale sharks, the aquarium contains beluga whales, sea lions, sea otters, manta rays, and countless species of fish, jellyfish, and other marine creatures. Different sections of the aquarium recreate different ocean environments: tropical coral reefs, cold Arctic waters, and the open ocean. This variety means visitors can see animals from nearly every marine habitat on Earth within a single building.
The Main Exhibits and Their Water Requirements
The Oasis tank is the centerpiece of the Georgia Aquarium and the reason the facility holds so much water. This single tank contains 6.3 million gallons — more than half the aquarium's total water volume. It is designed to mimic the open ocean and houses the whale sharks, manta rays, and large schools of fish that need vast swimming space.
Other major exhibits include the Tropical Diver section, which recreates a coral reef environment with colorful fish and invertebrates, and the Cold Water Quest area, which houses beluga whales and other Arctic species. The Beluga Whale habitat alone requires millions of gallons to provide adequate space for these highly intelligent marine mammals. Each exhibit is carefully designed to match the natural conditions where the animals would live in the wild.
How the Aquarium Maintains Water Quality for So Many Animals
Keeping 11.5 million gallons of water clean and safe for animals is a massive undertaking. The Georgia Aquarium uses advanced filtration systems that run continuously to remove waste, maintain proper chemical balance, and keep oxygen levels stable. The facility employs a large team of marine biologists, veterinarians, and water quality specialists who monitor conditions around the clock.
The aquarium uses a combination of mechanical filtration, biological filtration, and chemical treatment to maintain water quality. Different exhibits require different salinity levels, temperatures, and pH levels depending on what animals live there. The tropical reef exhibits need warmer, saltier water than the Arctic exhibits. This means the facility actually maintains multiple separate water systems rather than one unified system, which adds to the complexity and cost of operations.
Visiting the Georgia Aquarium
The Georgia Aquarium is located in downtown Atlanta near the World of Coca-Cola and the National Center for Civil and Human Rights. It is open year-round, though hours vary by season. The facility attracts millions of visitors annually, making it one of the most visited aquariums in the United States.
Visitors can spend anywhere from two to four hours exploring the exhibits, depending on how much time they spend at each tank. The aquarium offers guided tours, interactive experiences, and special programs where visitors can learn more about marine conservation and the animals on display. Parking is available nearby, and the location is accessible by public transportation in Atlanta.
Why Size Matters for Aquarium Animals
The reason the Georgia Aquarium's size is significant goes beyond just being a record. Large water volumes allow animals to exhibit more natural behaviors. Whale sharks in small tanks often show signs of stress and shortened lifespans, but the massive Oasis tank gives them room to swim long distances and turn without hitting walls. Beluga whales, which are highly social and intelligent, benefit from the space to interact with other whales and explore their environment.
Water volume also affects how stable the environment remains. A larger body of water is more resistant to sudden changes in temperature, salinity, or chemical composition. This stability is crucial for animal health. When something goes wrong in a small tank, conditions can shift rapidly and harm the animals. In a massive tank like those at the Georgia Aquarium, the system has more buffer against problems, making it easier to maintain the precise conditions each species needs.
Frequently Asked Questions
How much does it cost to visit the Georgia Aquarium?
Admission prices vary depending on whether you visit on a weekday or weekend and whether you purchase tickets in advance or at the door. General admission typically ranges from $30 to $40 for adults, with discounts available for children, seniors, and military personnel. The aquarium also offers membership options for frequent visitors.
Can you touch the animals at the Georgia Aquarium?
Most animals cannot be touched, but the aquarium offers interactive experiences where visitors can touch certain species like stingrays and sea stars under staff supervision. These interactive areas are separate from the main exhibits and may require an additional fee or reservation.
How long does it take to see everything at the Georgia Aquarium?
Most visitors spend two to four hours exploring the exhibits. If you move quickly and skip the interactive experiences, you could see the main attractions in about two hours. If you watch the animal presentations, participate in interactive programs, and read all the educational materials, you could easily spend four hours or more.
Is the Georgia Aquarium still the largest in the world?
Yes, as of now, the Georgia Aquarium remains the world's largest by water volume. While other large aquariums have been built since 2005, none have exceeded its 11.5 million gallons of water. However, new facilities are occasionally announced, so this record could potentially change in the future.
Where exactly is the Georgia Aquarium located?
The Georgia Aquarium is located at 225 Baker Street in downtown Atlanta, Georgia, near the World of Coca-Cola and Centennial Olympic Park. It is easily accessible by car, and parking is available in nearby lots and garages. The location is also served by Atlanta's public transportation system.
