‘Granddad,’ Oldest Aquarium Fish In The World, Dies


The world’s oldest aquarium resident has passed away.

Known as Granddad,” the Australian lungfish had resided in a tank at the Shedd Aquarium in Chicago since 1933.

Shedd President and CEO Bridget Coughlin, Ph.D., said:

“It is incredible to know that more than 104 million guests had the opportunity to see Granddad in our care and learn about his unique species over eight decades.”

When first captured in Australia, Granddad was already a full-grown adult lungfish, so chances are it was probably close to (or past) the age of 100 when its health deteriorated earlier this month and aquarium officials decided to humanely euthanize it.
