Saltwater crocodile 'Cassius' is pictured in Marineland Melanisia at Green Island on the Great Barrier Reef in Queensland, Australia, on Sept. 15. Cassius was officially declared the 'World's Largest Crocodile in Captivity' by the Guinness Book of Records, measuring 5.48 metres and weighing close to a tonne.

Just who is the biggest crocodile of them all?

Cassius, an Australian saltwater crocodile named after Cassius Clay, has been declared the largest crocodile in captivity by the Guinness Book of Records. Cassius measures an impressive 5.48 meters (17 feet 11.75 inches).

He may not reign for long, though. As we reported on PhotoBlog, Filipino villagers captured a 6.4 meter (21 foot) crocodile earlier this month. Guinness World Records spokesman Chris Sheedy admitted that Cassius' title was already under threat, according to The Sydney Morning Herald.

"Until [the Filipino crocodile is] in acceptable captivity which is humane and professional, and until it has been properly measured, we can't accept it," Sheedy said.

    I wonder who gets the dubious honor of "officially" measuring the "new croc on the block?!?"
