Tragic Loss: Minnesota Zoo’s Beloved Amur Tiger Succumbs to Rare Cancer
In a sorrowful announcement that has sent ripples through the animal conservation community, the Minnesota Zoo confirmed the passing of _Sundari_, affectionately known as “_Dari_,” a 13-year-old female Amur tiger who was humanely euthanized in June 2025 following a rapid progression of mesothelioma, a devastating and aggressive cancer.
Understanding Mesothelioma
Mesothelioma is a rare form of cancer that specifically targets the mesothelial linings surrounding the lungs, abdomen, and heart. While this form of cancer is most commonly associated with humans who have been exposed to asbestos, a mineral made up of tiny fibers that can easily be inhaled or ingested, its occurrence in animals is significantly underreported. There have been only a few instances of mesothelioma in non-domesticated species, with most documented cases occurring in pet dogs.
Significance of Asbestos Exposure
Experts assert that asbestos exposure stands as one of the most prevalent triggers for mesothelioma in both humans and potentially susceptible animals. Interestingly, the cancer can also manifest in individuals with no known history of asbestos contact, adding layers of complexity to understanding its causes and implications.
Dari’s Remarkable Life and Legacy
Born in June 2012 at the Minnesota Zoo, Dari was a remarkable figure in the tiger conservation movement. Over her lifetime, she gave birth to six cubs—named _Vera_, _Brosno_, _Vostok_, _Yana_, _Amaliya_, and _Andrei_. Her maternal instincts and nurturing behavior exemplified the care and attention that species survival plans seek to foster in wild felid populations. Not only did she play a vital role in the zoo’s breeding program, but her exemplary maternal care has also served as an effective model for caring for tiger cubs in other institutions throughout the country.
Impact on Conservation Efforts
Dari’s impact extended beyond the walls of the Minnesota Zoo. As an ambassador for her species, she contributed significantly to various conservation and education initiatives aimed at preserving the endangered Amur tiger population, which currently stands at approximately 500 individuals remaining in the wild. Conservation efforts over the decades have showcased some degree of success in stabilizing and even increasing the population through managed breeding programs and habitat preservation.
Ongoing Conservation Initiatives
The Minnesota Zoo has long been an advocate for tiger conservation and actively participates in the Species Survival Plan (SSP) for Amur tigers. This plan is crucial, as it connects accredited zoos and aquariums to ensure genetically diverse populations and the well-being of these magnificent creatures. Additionally, the Tiger Conservation Fund, coordinated by the Association of Zoos and Aquariums, is being promoted to support ongoing efforts to protect tigers in their natural habitats.
A Final Goodbye
The zoo director described Dari as much more than just a tiger; she was a powerful symbol of her species and a beloved member of the community. Her untimely death from mesothelioma adds to the need for further research on the disease’s impact on animals, as understanding its ramifications could play a pivotal role in addressing similar cases in the future.
As the Minnesota Zoo mourns the loss of this beloved tiger, the legacy of Dari will undoubtedly continue through conservation efforts aimed at saving her endangered species from extinction.
