A 90-year-old Australian lungfish acquired by a Chicago aquarium in 1933 has been euthanised after becoming the longest-living fish in a zoological setting.
The fish, known as Granddad, was euthanised because of failing health, officials from the Shedd Aquarium announced.
Granddad came to Shedd from Australia in anticipation of the 1933-34 Chicago World's Fair and was seen by more than 104 million people during his time in Chicago, aquarium president Bridget Coughlin said.
"For a fish who spent much of his time imitating a fallen log, he sparked curiosity, excitement and wonder among guests of all ages who would hear his story and learn about the incredible biology that makes his species a living fossil and one of the oldest living vertebrate genera on the planet," Coughlin said.
