Rio, beloved river otter at Chicago aquarium, euthanized

CHICAGO, Oct. 30 (UPI) — The Shedd Aquarium in Chicago euthanized Rio, its only river otter, a fixture for the past two decades.

The aquarium announced the death Tuesday, the Chicago Sun-Times reported. Rio was 21.

Rio came to the aquarium as a pup from the Little Rock, Ark., zoo. She was a fixture in the At Home on the Great Lakes exhibit.

“It’s been a remarkable experience watching Rio inspire our guests throughout her years at the aquarium. As she grew older, Rio became a testament to the zoological community’s emerging expertise in geriatric animal care and welfare,” Source:
