Cassius, the world's largest crocodile in captivity, has passed away at a wildlife sanctuary on Green Island, Australia. Measuring nearly 5.5 metres (18 feet) long and weighing close to one tonne, Cassius was estimated to be over 110 years old, although his exact age was uncertain.

Captured in the Northern Territory during the 1980s, Cassius became a beloved tourist attraction at Marineland Melanesia, where he had lived for decades. In 2011, he was recognised by Guinness World Records as the largest crocodile in captivity.

The sanctuary announced his death on social media, referring to him as "our beloved mate" and a "cherished member of our family." Cassius had a reputation for his wild antics, previously known for catching cattle and attacking boat propellers before his capture.

George Craig, the habitat's founder, bought Cassius in 1987 and formed a deep bond with the crocodile over 37 years.

The habitat noted that Craig had recently relocated to Cairns, and Cassius's health declined shortly thereafter. "He was very old and believed to be living beyond the years of a wild croc," the sanctuary stated.

Marineland Melanesia expressed gratitude to all who visited Cassius during his life, adding that operations may be limited in the coming days as they mourn the loss of their iconic resident.
