The 42-year-old bear named Debby died on Monday at a zoo in Winnipeg, Manitoba, where she had lived since 1967 after being captured as a orphaned cub in the Russian Arctic in 1966.

Debby was in declining health due to her advanced age, and veterinarians decided to euthanize her after it was discovered she had suffered multiple organ failure.
She was listed as the world's oldest polar bear by the Guinness Book of World Records when she turned 41, according to officials at the Assiniboine Park Zoo.
