World’s largest crocodile, believed to be over 110 years old, is still growing

Cassius, an Australian saltwater crocodile, holds the Guinness World record for being the largest crocodile in captivity. Its caretakers say that the crocodile is still growing in size. A professor told Foxsnew.com website the crocodile measured 17 feet and 11.75 inches, 13 inches more that his visit nearly 20 years earlier. Guinness World record website also says that Cassius, the Australian saltwater crocodile, measured 17 ft 11.75 in.

Australian saltwater crocodiles can live for more than 100 years and can weigh more than 1 tonne. Cassius was brought about 3,200 km (1.988 miles) from Australia’s Northern Territory to Green Island in 1987, by truck, according to Guinness World website.

Cassius has lived at the Marineland Crocodile Park for over 30 years. According to Marineland Crocodile Park website, Cassius was captured in 1984 in the Finis River, Northern Territory Australia.


"Where Cassius was captured in the Finis River, he was the boss - all other creatures living nearby him would have known and feared him, this is evident from the various battle wounds and scars he carries as a reminder of his younger years living in the wild. He was also notorious for attacking boats and biting off outboard motors for lunch and it may be a spinning propellor that left his snout slightly shorter," according to Marineland Crocodile Park website.

According to the website, Marineland Crocodile Park's founder George Craig often likes to personally feed Cassius. "You will be amazed by the special connection he has developed with this incredible animal after nearly 30 years of being his caretaker," says the website.

The age of Cassius is estimated to be between 110 and 120 years. According to Oldest.org, the oldest crocodile in captivity on record was Freshie, who lived for 140 years. Freshie was caught in 1970 by Steve Irwin and his father, Bob Irwin, in the Moorehead River. Freshie resided in a zoo in Queensland, Australia.
