So, here’s the quick answer: Debby holds the record as the oldest known polar bear, living to about 41 years old at Winnipeg’s Assiniboine Park Zoo.
Guinness World Records recognized Debby for her age, which is pretty remarkable since most polar bears in human care live about 20–25 years, and wild bears don’t make it nearly as long.
Debby’s life looked very different from that of wild bears. What made her live so long? And what does her story mean for polar bear care and conservation now?
Let’s look at Debby’s history, what affects polar bear lifespan, and how zoos and conservationists try to protect these animals.
Debby: The Oldest Polar Bear in the World
Debby spent her whole life at the Assiniboine Park Zoo in Winnipeg. She started out in the Arctic, set a world record, and became a local legend.
People still talk about her today.
Early Life and Arrival at Assiniboine Park Zoo
Debby was born around 1966 in the Soviet Arctic. She lost her mother as a cub.
She arrived in Winnipeg in 1967, about a year old, along with another cub named Dennis. Dennis eventually went to the Calgary Zoo.
Zoo staff cared for Debby, giving her food and shelter so she could grow.
Imagine her early days—just a rescued cub, getting used to a new home at the Assiniboine Park Zoo.
Keepers named her Debby and moved her into a polar bear habitat built back in 1958. By today’s standards, it was pretty outdated.
Guinness World Record and Official Age
Guinness World Records named Debby the oldest polar bear alive in August 2008, when she hit 41.
Some reports say she was 41, others say 42—her exact birth date wasn’t known. Guinness also called her one of the oldest bears ever, across all species.
She got there thanks to decades of careful attention, regular vet checks, and a solid diet.
Zoo staff gave credit to her good genes, steady food, daily activity, and keepers who spotted medical issues early.
Life at the Winnipeg Zoo
At the zoo, Debby became a favorite with visitors. She was front and center in zoo life.
People would watch her swim in the pond, snack on veggie dogs and smoked goldeye, or play with keepers.
Her keepers described her as playful and always looking for food.
She had a mate, Skipper, and together they raised six cubs. All six were alive when Debby died.
Debby weighed over 300 kilograms when she was healthy. She inspired books, zoo programs, and even children’s stories.
Kids and adults learned about polar bears and conservation through her story.
Memorials and Lasting Impact
Debby died on November 17, 2008. The zoo held a memorial with songs, speeches, and a smudging ceremony.
If you visit the park, you’ll see a statue of Debby by Charles Johnston. Some of her ashes are inside, making it a special local tribute.
Her passing made the zoo rethink how they housed polar bears. Debby’s old concrete enclosure no longer met Manitoba’s standards.
The zoo later opened a new Polar Bear Conservation Centre and brought in a new bear, Hudson, in 2013.

Polar Bear Longevity and Conservation
Polar bears live longer when they have safe, steady conditions. When food and sea ice run short, their lives get cut short.
Let’s talk about how age differs between wild and captive bears, why health and laws matter, and what zoos and centers do for science and education.
Lifespan of Polar Bears in the Wild and Captivity
Wild polar bears usually live about 15–25 years. Their survival depends on sea ice for hunting seals.
Young bears have it rough—starvation, storms, and predators claim many. Some wild bears make it to their 30s, but that’s rare.
In captivity, bears often outlive their wild cousins. Debby reached 41 at the Assiniboine Park Zoo, setting a record.
Zoos control diet, treat illnesses, and keep out threats like hunting. That stability pushes many captive bears into their 30s.
Some regions do better than others. Bears in parts of the Arctic with stable food and fewer human conflicts tend to live longer.
Conservation centers in Europe, Asia, and North America track these patterns and collect important data.
Factors Affecting Polar Bear Lifespan
Nutrition comes first. Regular access to seals and fat reserves keeps bears healthy and able to raise cubs.
When ice conditions get bad, bears have to swim farther and hunt less, which hurts survival for both cubs and adults.
Disease and injury take a toll too. Older bears deal with organ decline and strokes, just like Debby did.
Human threats—hunting, pollution, ship strikes—add more danger. Laws and protected areas help by limiting hunting and development.
Genetics and individual care play a role. Some bears just have the right genes for long life.
In zoos, vet care and enriched habitats lower stress and help bears live longer.
Events like Fat Bear Week get people thinking about weight and health in wild bears.
Role of Zoos and Conservation Centers
Zoos and dedicated centers give animals food, medical care, and safe places to live. The Polar Bear Conservation Center and Assiniboine Park Zoo work hard to care for animals and teach the public.
Staff run breeding programs and keep an eye on the animals’ health. They also keep records for the long term.
These places back up science and law, too. Researchers use their data to study climate impacts, and policymakers often ask for their advice about protections.
Education programs show visitors in the US, Europe, and Asia why habitat loss matters. They also talk about legal tools that might help bears.
If you want to pitch in, you could visit accredited programs, donate to conservation centers, or follow research from places like Cheyenne Mountain Zoo and international nature reserves. Every bit helps fund rescue, research, and advocacy for polar bears and other bears.
