Marineland Melanesia Crocodile Habitat said in a social media post that Cassius was “our beloved partner” and a “respected member of our family”.
Cassius used to live in the wild where he was known for catching and eating cattle and attacking boat propellers before he was captured.
The Australian Broadcasting Corporation reported that Habitat founder George Craig purchased Cassius in 1987.
Cassius “brought joy and companionship to his best mate George for over 37 years,” Habitat said in a statement.
