The World’s Largest Crocodile Cassius Passes Away at 110
GREEN ISLAND, Australia - Cassius, the world’s largest crocodile in captivity, has died at the Marineland Melanesia sanctuary on Green Island, having lived more than 110 years. Known for his sheer size—nearly 5.5 meters (approximately 18 feet) long and weighing close to one tonne (around 2,000 pounds)—Cassius had earned recognition as the largest crocodile by Guinness World Records back in 2011. The crocodile had begun showing signs of declining health earlier this month, with sanctuary staff confirming the news of his passing on social media.
His sanctuary, where he had resided since 1987, noted on Instagram, "Cassius's condition declined since the 15th of October. He was very old and believed to be living beyond the years of a wild croc." This statement reflects not just the physical decline of the majestic reptile, but also hints at the emotional bond forged over three decades between Cassius and George Craig, the sanctuary’s founder who had grown particularly close to him.
Originally captured from the Northern Territory during the 1980s, Cassius had become well-loved as both a local attraction and as part of the community around Green Island. Known for his larger-than-life antics, he had previously made headlines for his fearsome ability to hunt among the cattle and for his past adventures, which included occasionally wreaking havoc on boat propellers. The habitat expressed deep grief, stating, "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."
Toody Scott, who was responsible for Cassius’s daily care, remembered him fondly, referring to him as “a sweetheart” and explaining how his impressive eyes could draw you in. “His big, dreamy eyes could make you lose yourself for hours,” Scott reminisced. He shared the importance of caution around such wild creatures, reminding everyone, "Though he had a gentle nature, we always had to be mindful of who he was—a crocodile at heart, cunning and wise. Treating him kindly meant also treating him with respect, especially when it came to feeding time!"
The sanctuary offered their thanks to the countless visitors who had come to see Cassius over the years, adding, "Everyone who visited Cassius throughout his life shared kindness, and the memories we created will live on forever." They also hinted at possible changes to operations at the sanctuary as they mourn their iconic resident.
Beyond his impressive record, Cassius served as both the heart of the Marineland Melanesia and as an ambassador for crocodile species worldwide. Since his days catching cattle and swimming near boaters, he had transitioned to life as the gentle giant of the sanctuary, often adored by tourists and locals alike.
Cassius lived through many phases of life, outlasting most of his peers and becoming synonymous with the area’s wildlife tourism initiatives. His record will leave behind not just statistics, but stories shared by those who were lucky to witness his vivid personality up close.
His 2011 award from Guinness World Records not only put him on record as the largest crocodile but opened discussions about the care and conservation efforts toward crocs and their habitats—conversations which are more important now than ever as many species face threats from habitat loss and climate change.
While Cassius has gone, he will live on in the memories of both caretakers and the public who met him. The Marineland Melanesia sanctuary has promised to continue educating visitors about crocodiles and the importance of conservation, echoing Cassius's legacy beyond the physical closure of this chapter. “Cassius will be deeply missed, but our love and memories of him will remain in our hearts forever,” they stated.
The crocodile's story is one of survival and companionship, spanning over three decades within the sanctuary walls. It serves as both heartbreak and celebration; as they say goodbye to their beloved friend, they look forward to ensuring his legacy lives on through continued efforts for wildlife conservation. For all the adrenaline he provided and the lessons learned, Cassius's life was nothing short of legendary.
The death of this iconic figure not only highlights the individual story of Cassius but shines a spotlight on the species as we discuss the wider relevance of crocodilian conservation. Each crocodile is not only part of their ecosystem but also linked to the communities they inhabit—making Cassius’s legacy important and wide-reaching. His life will serve as inspiration to many, highlighting the strength of bonds formed between humans and animals alike.
Marineland Melanesia has invited those who knew him well to share their stories and fond memories as they navigate their grieving period, reminding folks from all walks of life of the joy and depth of companionship our animal friends can bring. Through Cassius, many learned about the majesty of nature, the need for conservation, and the deep emotional connections we form with creatures—large and small.
