CHICAGO (AP) - The veterinary staff at Chicago’s Shedd Aquarium has euthanized a long-time resident river otter because of deteriorating health.

At 21 years old, Rio lived nearly a decade beyond the species’ median life expectancy of 12 years.

The Shedd Aquarium says despite her age, Rio still had a zest for swimming around her exhibit and playing with toys, especially those stuffed with food.

But the aquarium says she was euthanized Tuesday because her quality of life had diminished.

Ken Ramirez is vice president of animal care and training. He says “Rio became a testament to the zoological community’s emerging expertise in geriatric animal care and welfare.”

Rio came to Chicago from the Little Rock Zoo in Arkansas in 1992 at a time when river otters were considered endangered in Illinois.
