Shedd To Celebrate Birthday Of Oldest Living Fish In Captivity

Granddad is an Australian Lungfish with both gills and one lung and fins that help him crawl from a dry puddle to one that still has water.

Sattler says he’ll be honored for making 80 years at least with an aquatic birthday cake in the morning.

“The base of it is ice to hold together all of his favorite treats, melt, krill, clam, grapes, lettuce,” said Sattler.

For all the hoopla surrounding this esteemed senior, Granddad seems unmoved—literally. At 25 pounds and 4 feet long, he lingers near the habitat floor like a fallen log. Except to catch some air.
