Brave keepers: George Craig (left) and Toody Scott (right) watch over Cassius Clay the croc at Marineland Melanesia on Green Island in Australia as his pool is drained
As the name suggests, he is a powerful heavyweight with a bit of bite.
But this Cassius Clay will not be going into the Guinness Book of Records for his killer uppercut - weighing in at close to a tonne and measuring 18ft in length, he is the biggest captive crocodile in the world.
The saltwater croc is believed to be at least 100-years-old and has lived in Marineland Melanesia on Green Island in Australia, for 24 years.
And this photograph shows the croc’s brave owner George Craig watching over Cassius’s pool being drained so he could be officially measured for the title.

Fellow Marineland Melanesia keeper Toody Scott said he was ‘ecstatic’ about Cassius claiming the record.
He told Cairns.com.au: ‘It confirms our belief that we’ve got the biggest croc, and it’s good that he’s got a bit of recognition for it.’
Cassius was captured in 1984, just south of Darwin, before being transferred to Green Island, which is located 17 miles offshore from Cairns, in Australia’s Great Barrier Reef.
He was taken into captivity after attacking too many boats in Darwin and was relocated to his current home in 1987.
His diet mainly consists of fish and chickens, which has led to his massive growth over the years.

Despite Cassius nabbing a spot in the 2012 edition of the Guinness Book of World Records though, a spokesman from the organisation said his glory might be short lived.
Guinness World Records spokesman Chris Sheedy said that the crocodile’s record may be brief, after reports earlier this month of a 6.4 metre (21ft) aquatic beast that was trapped in the southern Philippines.
The croc, named Lolong, was found in the township of Bunawan, weighs a tonne and is 6.4 metres (2ft) long.
