Cassius , who wasthe earth ’s orotund living captive crocodile , die in Australia this month after 40 years in captivity . Experts forecast the gigantic saltwater croc ( Crocodylus porosus)could have been over 120 years previous — but they do n’t sleep with for indisputable .
Cassius, who was the world’s biggest captive crocodile until his death early November.
Sally Isberg , father of the Centre for Crocodile Research in Australia ’s Northern Territory , tell ABC Newsthat " all indications at this stage indicate that he has die of [ old age ] . "
But further test be the beast autopsy , which will be carry out imminently , may also let on the 17 feet and 11.75 inch ( 5.5 meter ) croc ’s precise eld , something that even his keepers — who made up his birthday — had never been sure of .
When Cassius was captured in the Finniss River , near Darwin , in 1984 , researchers believe he may have been up to 80 eld sometime . But once crocodile fully mature , their growth pace slow up down , make it unacceptable to determine his exact geezerhood .
Cassius living in captivity for 40 years, and may have been 80 when he was first captured.
" There is no way of make love Cassius ' literal age as he was born in the wild and the eld is just an estimate , " Toody Scott , one of Cassius ' keepers at Marineland Crocodile Park , previouslytold Live Science .

However , it could take months before the solution are back and the process is n’t undertake to work , she contribute . " I ’m a little fleck implicated that those growth rings might not be quite as well discernible . "
Grahame Webb , a zoologist and conduct crocodile researcher , helped capture Cassius from the wilderness in 1984 after the fast-growing croc started attack cattle and boat propeller . He told ABC News that counting growing ring might not give an accurate age estimation . " These animals stop growing and they can live for ten afterwards without growing , " he aver .
Cassius Longinus evaluate just under 18 pes ( 5.5 m ) long when he died . However , he was also missing part of his snout and the end of his tail end . Without these battle scars , Webb believes the crocodile would have reached a full duration of 19 feet ( 5.8 m ) .
