The world's largest crocodile in captivity¹, Cassius, died at a wildlife sanctuary² in Australia.

The Marineland Melanesia Crocodile Habitat & Gift Shop posted on Facebook about the loss of Cassius.

"It is with deep sadness that we share the passing of our beloved mate Cassius," the post read. "He was more than just a crocodile he was a cherished member of our family and brought joy and companionship to his best mate George for over 37 years."

Cassius, a saltwater crocodile, was thought to be at least 110 years old, according to the BBC, but no one is certain.
