Loggerhead Sea Turtles Return Home After Rehabilitation Journey

This spring, Georgia Aquarium celebrated a milestone in sea turtle conservation – the release of eight rehabilitated loggerhead sea turtles into the Atlantic Ocean, just off the shores of Jekyll Island.

These turtles’ journey began in early December 2024, when they were found cold-stunned in the icy waters off Cape Cod. Like all sea turtle species, loggerheads are cold-blooded and rely on warm ocean temperatures. When the water drops too quickly, they can become hypothermic, weak, and unable to swim – a life-threatening condition called cold-stunning.

The turtles received the initial round of life-saving care at the New England Aquarium (NEAQ) before being transported to Georgia Aquarium’s off-site animal care facility in mid-December. Their cross-country trip was made possible thanks to the incredible volunteer pilots from Turtles Fly Too, who routinely transport sea turtles to warmer waters and second-stage care facilities nationwide. The trip itself is a remarkable story of teamwork and just the beginning of their road to recovery.

Why Loggerheads? Why Georgia Aquarium?

Loggerhead sea turtles are one of the largest species of sea turtle. Because of their size and strength, not every facility can accommodate them. Georgia Aquarium’s off-site animal care facility is one of only a few U.S. facilities with the specialized space and expertise to care for these endangered giants. The facility is uniquely equipped to give them the room, warmth, and expert veterinary attention needed to heal. The Aquarium’s aquatic sustainability team cared for them with feedings, monitoring their health, and additional animal care support for the entirety of their stay at the off-site facility.

Over the past five years, Georgia Aquarium has taken in a total of 44 cold-stunned sea turtles – each one a step toward protecting this species, which is endangered in the United States.

Upon arrival, the turtles were carefully assessed and treated for various cold-stunning complications, including pneumonia. Each turtle responded quickly to care, regained strength, and began eating well – signs of a hopeful outcome. While each loggerhead had its own story, their resilience was a common thread.

Ready to be Released

After being cleared by our veterinary staff, the turtles were prepped for release. Before their big return to the ocean, all eight were fitted with flipper tags to help identify them if they are reencountered. Two turtles, affectionately named Poblano and Bell, were also equipped with satellite tracking devices. These tags will provide valuable data on their movements and help scientists better understand the migratory patterns of this species.

At the end of March, with the support of our longtime partners at the Georgia Department of Natural Resources (DNR), our aquatic sustainability team – including Mark Olsen, Polly Strott, and Stephanie Salter – traveled to Great Dunes Beach on Jekyll Island to witness the turtles’ long-awaited return to the Atlantic.

The day of the release brought clear skies and a brisk ocean breeze. While the windy conditions meant the team couldn’t release from the boat, it made for a beautiful, shoreline send-off. “Watching them swim away never gets old,” shared Mark Olsen, associate curator of aquatic sustainability at Georgia Aquarium. “It’s a reminder of why we do this work and how far these animals have come.”

How You Can Help

Like many sea turtle species, loggerhead sea turtles face numerous threats in the wild, from climate change to habitat loss and marine debris. Each turtle we rescue and release plays a role in restoring balance to our marine ecosystems, and every success story is a testament to what we can achieve together.

Fortunately, the U.S. has a strong network of government agencies, organizations, and volunteers that work together during cold-stunning events. This network not only plans for these emergencies in advance but also uses alert systems to mobilize people to search for and assist stranded turtles.

This year being our 20th anniversary year, we’re proud to take that commitment beyond our walls. This is more than a day of service—it’s a celebration of two decades of conservation, community, and connection. We’re so grateful to the Atlanta community for supporting us over the years, and this is one small way we can give back. 

Happy Earth Day, Atlanta—let’s keep making waves for good. 🌎💙

Stories of Survival: Georgia Aquarium’s Rescued Residents

At Georgia Aquarium, every animal has a story, but some have overcome incredible odds to find their forever home with us. From sea turtles to sea lions, these animals have been given a second chance thanks to dedicated rescue efforts and support from organizations like ours. Here are some of their remarkable stories:

Stories of Survival: Georgia Aquarium’s Rescued ResidentsTank the Sea Turtle

Tank’s journey began in 1990 when he was rescued after suffering a shark bite to his left rear flipper. Initially rehabilitated at the New York Aquarium, Tank spent time at several zoological facilities, including Disney’s The Seas at Epcot. He first arrived at Georgia Aquarium in 2010 before moving to Marineland Dolphin Adventure in Florida in 2014. In 2015, he returned to Georgia Aquarium, where he now resides in our Ocean Voyager exhibit. At over five feet long and weighing more than 450 pounds, Tank is a true survivor and ambassador for sea turtle conservation.

Stories of Survival: Georgia Aquarium’s Rescued Residents 1Nandi the Manta Ray

In 2007, Nandi was accidentally caught in a shark net off the coast of Durban, South Africa. She spent a year rehabilitating at uShaka Marine World, but due to her size and care needs, officials sought a permanent home for her. Georgia Aquarium stepped in, arranging a remarkable 26-hour, 9,000-mile journey via Jumbo Jet to bring her to Atlanta. Just days after her arrival, she was thriving in her new environment. Manta rays are gentle, endangered giants, and Nandi helps raise awareness about their conservation needs.

Southern Sea Otters: Brighton, Cruz, Bixby, Mara, and Gibson

Each of these rescued sea otters was orphaned at a young age and deemed non-releasable by wildlife officials. Brighton, found in 2010, had medical issues from consuming non-typical food items. Cruz and Bixby, rescued separately the same year, lost their mothers to great white shark attacks. After receiving care at Monterey Bay Aquarium, all three arrived at Georgia Aquarium. They now serve as key figures in educating guests about the importance of marine mammal rescue and rehabilitation. 

Mara and Gibson, the two newest members of the Aquarium’s sea otter family, also have inspiring stories. Mara was rescued in 2022 after being found stranded and alone as a pup. Wildlife experts determined she lacked the survival skills to be released back into the wild. Gibson, rescued as an infant in 2023, was also orphaned and needed round-the-clock care before being deemed non-releasable. Both otters have since found a safe and loving home at Georgia Aquarium, where they continue to receive expert care and help educate the public about conservation efforts for this threatened species.

California Sea Lions: Rescued and Rehabilitated

Several of Georgia Aquarium’s sea lions have unique and heartwarming rescue stories:

  • Diego stranded three separate times in California before being deemed unreleaseable after he was found malnourished and hiding underneath a police car. Diego, now weighing up to 700lbs at his heaviest, has served as larger than life ambassador for his species since first coming to Georgia Aquarium in 2005. 
  • Scout, Beck, Jupiter, and Neptune each stranded multiple times due to malnutrition and maternal separation, making them unfit for release. They arrived at Georgia Aquarium between August and September 2015 after receiving temporary care at various marine rescue centers. Upon his arrival to the Aquarium, Neptune underwent various examinations, where x-ray results showed he had two bullet fragments in his head. 
  • Hunter stranded an astonishing four times, once even voluntarily jumping into a rescue boat! After suffering from boat propeller wounds and eye issues, he came to Georgia Aquarium in 2017, where he underwent surgery and continues to receive expert care.
  • Alex, found in 2014 with severe eye damage, was deemed non-releasable. After arriving at Georgia Aquarium in 2018, he underwent surgery to remove his left eye but continues to thrive in his new home.

Confiscated Corals & Motoro Rays

Since 2005, Georgia Aquarium has provided sanctuary for over 1,000 animals confiscated by the U.S. Fish and Wildlife Service (USFWS), including nearly 600 corals. These corals, brought into the country illegally, cannot be returned to the ocean due to genetic and ecological concerns. Georgia Aquarium has provided a forever home to nearly 300 of them, ensuring their survival and contributing to coral conservation efforts. Additionally, motoro rays and other animals have found refuge here after being intercepted in the illegal wildlife trade.

A Second Chance at Life

Each of these animals represents the incredible work done by rescue organizations, aquariums, and conservationists worldwide. At Georgia Aquarium, we are honored to provide a permanent, caring home for these rescued animals while using their stories to inspire action in marine conservation. Their journeys remind us of the impact we can have in protecting the ocean and its inhabitants.

The Secret Journeys of Giant Tiger Sharks

Adult tiger sharks, as big as cars, swim thousands of miles across the ocean every year, but their migration patterns have been elusive. Scientists have been studying tiger sharks for years, including Dr. Lisa Hoopes, senior director of research and conservation at Georgia Aquarium. Recently, special satellite tags have been used to track their movements to learn where these sharks go and why. A new study, published in the science journal Marine Environment Research, followed 35 of the largest tiger sharks ever monitored (most of them adult females), and what they discovered was astounding.

Super Travelers of the Sea

Tiger sharks are like long-distance ocean explorers. The longest journey recorded in this study was over 17,000 kilometers (10,500 miles) in 468 days—that’s like swimming from New York to Australia!

Despite their long journeys, these sharks exhibit a strong tendency to return to the same place —Norfolk Island, a small island in the Pacific Ocean. Nearly 90% of the tracked sharks revisited this location after their travels.

Why Do They Keep Coming Back?

Scientists found that water temperature plays a big role in when the sharks leave and when they return. Just like birds migrate to warmer places in winter, tiger sharks seem to time their movements based on ocean conditions. The study showed that the sharks usually arrive at Norfolk Island in December and leave around May.

What remains a mystery—and an area for future study—is whether reproductive factors influence their migration patterns.

When not at Norfolk Island, these sharks’ favorite destinations include New Caledonia, the Great Barrier Reef, Fiji, and even New Zealand.

Coastal Areas Are Important for Sharks

Another big discovery in the study was that tiger sharks love hanging out near coastal areas. These places seem to be important for them, possibly because they provide food and shelter.

Scientists now understand that Norfolk Island and other nearshore areas are critical for these tiger sharks, especially large females. Protecting these areas can help ensure these top predators continue to play their important role in the ocean’s ecosystem.

Why Does This Matter?

Sharks are often misunderstood, but they are key players in keeping the ocean healthy. They help control fish populations and keep marine life in balance. Learning about where they go and what influences their movements can help scientists and conservationists protect them.

This research provides new insights into the lives of these incredible ocean wanderers and their secret migration patterns. Thanks to satellite tracking, researchers are finally learning where they go, when, and why.

This study on tiger sharks was done in collaboration and with support from Flinders University in Adelaide, Australia, Biopixel Oceans Foundation, Norfolk Island National Park, New South Wales Department of Primary Industries and Regional Development Port Stephens Fisheries Institute, and Georgia Aquarium.

Exploring the Mysteries of Whale Sharks: A Groundbreaking Expedition to Wreck Bay

In the remote northern reaches of the Great Barrier Reef lies a previously unknown whale shark aggregation in an area called Wreck Bay. Recently, Dr. Cameron Perry, a research scientist from Georgia Aquarium’s conservation team, embarked on a 10-day expedition to this secluded region. The goal? To deepen our understanding of whale sharks and their elusive behaviors, while also furthering conservation efforts.

Exploring the Mysteries of Whale Sharks: A Groundbreaking Expedition to Wreck Bay

A Needle in a Vast Ocean

The story of discovering whale sharks in Wreck Bay is nothing short of remarkable. Finding whale sharks within a large ocean basin is literally equivalent to finding a needle in a haystack. While Ningaloo Reef in Western Australia has long been a hub for whale shark research, the lack of whale shark sightings along the eastern coast represented a large data gap for whale shark populations in the southwest Pacific. 

However, researchers from Biopixel Ocean Foundation, Georgia Aquarium’s partner on this project, suspected suitable habitats existed along the eastern coast of Australia. Using environmental modeling—analyzing sea surface temperature, bathymetry, and marine productivity—they were able to identify a potential whale shark habitat. Thus, the first expeditions to Wreck Bay began.

Uncovering the Mysteries at Wreck Bay: Expedition Highlights

Over seven days in Wreck Bay, the research team encountered 45 whale sharks, identifying over 25 unique individuals and nearly doubling previous photo-ID records. But numbers tell only part of the story.

Groundbreaking Research Techniques

We deployed 15 tags on 14 individuals, using a mix of tracking technologies:

  • Location tracking tags (SPOT)
  • Advanced movement and environmental data tags (SPLASH10)
  • Five special deep-dive tags capable of withstanding pressures at 2,500 meters depth

“This trip was incredibly successful,” said Dr. Perry. “Not only did we identify new individuals, but we also deployed 15 cutting-edge tags to track their vertical and horizontal movements, as well as environmental data.” 

Particularly noteworthy is the potential to document the deepest whale shark dive to date, surpassing the current record of 1,928 meters. 

Why This Matters

Wreck Bay’s story is one of persistence and discovery. For years, researchers believed that whale sharks were confined to Western Australia. Identifying Wreck Bay as an aggregation site has sparked numerous expeditions, providing valuable insights and data on whale shark movement patterns.

“Studying this population is crucial because it fills a critical data gap for whale sharks in the Southwest Pacific,” Dr. Perry explained. “While there are still significant data gaps in our understanding of whale shark populations. This expedition helps us build a more comprehensive picture of their movements, behaviors, and potential threats.”

The team also conducted pioneering research during this expedition, including:

  • The first camera tag deployment on whale sharks along Eastern Australia
  • Capturing microplastic samples to assess potential threats
  • Collection of 17 biopsy samples – which will be used to study the genetics and feeding ecology of whale sharks within Wreck Bay

A Collaborative Effort

Field research on this scale requires a village. Georgia Aquarium, in partnership with organizations like Conservation International, Marine Megafauna Foundation, and Biopixel Ocean Foundation, pooled resources to make this expedition possible. 

“This expedition exemplifies the power of collaborative research,” said Dr. Perry. “By combining resources from other organizations, we maximize our potential for discovery.” 

The team’s efforts also extended beyond whale sharks. They tagged tiger sharks in southern reefs, collected genetic samples, and tracked sightings of other marine megafauna, such as oceanic manta rays and the rare Omura’s whale.

Looking Ahead

Georgia Aquarium’s work in Wreck Bay is just the beginning. The next steps include analyzing data from the tags, expanding habitat suitability models, and engaging with local communities to deepen understanding of whale shark movements. Plans are already underway to explore new regions further south, with the help of Marlin fishermen who report occasional sightings of these gentle giants.

For Dr. Perry, the mystery of whale sharks is what keeps him passionate about this work. “They’re the largest fish in the sea, yet we know so little about them.”

This expedition underscores Georgia Aquarium’s commitment to advancing marine conservation on a global scale. By bridging gaps in knowledge and fostering collaborations, these efforts help protect not only whale sharks but the ecosystems they call home.

Tracking Sharks and Rays: A Collaborative Dive into Marine Research with Chi-Ju Yu (Debbie)

In the vast mysteries surrounding ocean life, few creatures captivate the imagination like sharks and rays. But beyond fascination lies the crucial work of research and conservation—a mission that Chi-Ju Yu (Debbie), a postdoctoral researcher from Dr. Shoou-Jeng Joung’s lab at National Taiwan Ocean University, knows well. Her journey in marine research began 13 years ago and has taken her across continents, most recently bringing her to Georgia Aquarium for a collaborative project aimed at improving the understanding and management of these species.

A Passion Born in the Classroom  

Debbie’s love for sharks was ignited during a Fisheries Dynamic and Chondrichthyes class taught by Dr. Joung. “Through the course, I realized Taiwan needs more researchers focusing on sustainable fisheries management,” she explains. This realization propelled her to join Dr. Joung’s team and dedicate herself to shark and ray research. 

Her postdoctoral work currently involves using acoustic telemetry, a technique that tracks animal movements by attaching tags that communicate with underwater receivers. Supported by the Georgia Aquarium, this project aims to monitor large species, such as whale sharks and Taiwanese wedgefish, within Taiwan’s waters.  

Collaborative Research Across Oceans  

Debbie’s research goes beyond tracking sharks. She’s working with the Fisheries Research Institute (FRI) and Georgia Aquarium to deploy acoustic receivers around Taiwan. These tools help detect tagged marine animals and gather data on their movements and behaviors. “I’ve also participated in satellite tagging programs for whale sharks and studies on the scalloped hammerhead shark in Western Taiwan,” she adds. 

Her visit to Georgia Aquarium offered invaluable insights. “I wanted to observe the Aquarium’s animal monitoring, handling techniques, and fieldwork,” Debbie shares. It also provided an opportunity to explore future collaborative projects. “Research challenges differ between regions, and Taiwan’s work is often limited by funding, staff, and techniques. Collaborating with Georgia Aquarium helps us address these gaps and fosters a mutual exchange.”

Learning from the Experts  

While at Georgia Aquarium, Debbie immersed herself in various activities, from feeding animals in the Ocean Voyager exhibit to assisting with assessments in the field. “I even got to take my first blood sample from a shark and implant an acoustic transmitter with Dr. Lisa Hoopes and Dr. Kady Lyons,” she recalls fondly. 

Her time with the Aquarium’s teams reinforced the importance of different monitoring techniques—ultrasound examinations, behavior tracking, and data analysis—all essential tools for understanding marine life. “Although I couldn’t observe everything the Aquarium’s team does, every moment spent here was priceless.”

Facing Challenges in Shark Research  

Field research presents unique hurdles, from safety risks to the unpredictability of wildlife encounters. “The biggest challenge is that you can’t always get the sample or data you need,” Debbie reflects. In Taiwan, habitat destruction and fishing practices also pose significant threats to sharks. However, the country has adopted sustainable management strategies, including whole-fish utilization and bycatch monitoring under international guidelines. Despite these efforts, Debbie notes that traditional surveys remain insufficient, underlining the need for continued research and international collaboration.

A Global Vision for Shark Conservation  

Debbie’s work highlights how acoustic tracking programs foster global conservation efforts. “Our receivers might detect species tagged by other research teams, and our tagged sharks could be tracked in other regions,” she explains. Connecting nations like Taiwan, Australia, the Philippines, and Japan could yield crucial insights into the movement patterns, population structures, and life stages of marine animals. “These collaborative efforts will help us develop sustainable resource management strategies.” 

Priceless Memories and a Hopeful Future  

For Debbie, her time with Georgia Aquarium wasn’t just about research—it was also about meaningful experiences. “I saw how the Ocean Voyager team creates unique feeding plans for the whale sharks and conducts regular health checks. I even got to dive with the team and assist in training activities.” 

Her gratitude for the experience is evident. “This opportunity to learn and explore means so much to me. I hope to meet everyone again soon, and they’re always welcome to visit me in Taiwan.”  

Debbie’s work is a testament to the power of collaboration in advancing marine conservation. With every tag deployed and every data point collected, she moves one step closer to ensuring the future of these majestic creatures—both in Taiwan’s waters and across the globe.
