World's largest captive croc turns 120, giving scientists 'serious knowledge on longevity'

[Still Waters]

Cassius, the world's largest crocodile living in captivity, just turned 120 years old. Or at least that's his estimated age, scientists say. 

It's difficult to determine a crocodile's age based on its size. Once they reach adulthood, the rate at which crocodiles grow slows down and eventually grinds to a halt. The largest crocodiles are usually the ones that grow in irregular spurts as juveniles, with males typically growing bigger than females.

"There is no way of knowing Cassius' actual age as he was born in the wild and the age is just an estimate," Toody Scott, a crocodile keeper who looks after Cassius at Marineland Crocodile Park on Green Island, told Live Science in an email. The nearly 18-foot-long (5.5 meters) saltwater giant's birthday "was essentially made up a few years ago" and this time of year is actually "the wrong time of year for a crocodile to be born in northern Australia," Scott added.

The key to long life. Eat raw chicken with the feathers.

I can imagine it gets a bit boring after spending 120 years in a cage of 3x4 meters.
