Chicago aquarium euthanizes more than 90-year-old lungfish

CHICAGO (AP) — An Australian lungfish that entranced visitors to Chicago's Shedd Aquarium for more than 80 years has been euthanized due to old age, the popular tourist attraction announced Monday.

"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," said Bridget C. Coughlin, Shedd Aquarium's president and chief executive officer.

"Granddad lived a pretty relaxed life, enjoyed interactions with us, including gentle pats along his back, and loved to eat his leafy greens," said Michelle Sattler, who was Granddad's caretaker for more than 30 years.
