Giant north Queensland crocodile Cassius may now be largest in captivity after death of Philippines monster SAD END: The Philippines giant was almost as long as a Toyota Coaster minibus. A MONSTER north Queensland crocodile named Cassius may again be the world's biggest in captivity after the global title-holder died in the Philippines. Marineland Melanesia Crocodile Farm on Green Island, off Cairns, has been home to the 5.5m monster named Cassius, which was officially the largest crocodile in captivity until villagers in the Philippines captured a 6.17m dinosaur in 2011. The Philippines giant died over the weekend, with a local vet unable to save it.

Marineland Melanesia manager Billy Craig said the death of the Philippines croc came as a shock. "It's a shame to hear that this magnificent animal has died but it's good news for Cassius as this puts him back on top," he said. Cassius is 110 years old and is in good health, eating well and is expected to live for many years. TALE OF THE TAPE: This file image shows the Philippines crocodile nicknamed 'Lolong' being measured. If another croc larger than Cassius is ever captured, Queensland may well have a back-up claim to fame. In 2010 clawmarks were found near Normanton in the Gulf of Carpentaria from a crocodile estimated to be at least 6m long. A search for the monster revealed an extraordinary photograph. Normanton already boasts a monster crocodile story involving an 8.63m monster shot by Polish immigrant Krys Pawlowski on the banks of the Norman River in the 1950s. An imposing statue of that crocodile stands in the town.
