Also known as the Australian freshwater crocodile, or the Johnstones crocodile. Unlike the saltwater crocodile, this one has never been known to kill humans, though it has bitten regularly. Also thought to originate in Africa, and then radiate out, it is now quite different.
Not surprisingly, it is genetically closest related to the Philippine and New guinea crocodiles.
One has been seen, being eaten by a python after a struggle of 5 hours.
The population has unfortunately fallen dramatically due to the animals eating the invasive (and poisonous) cane toad. Currently there are thought to be around 100,000, though this may well continue to fall, if the cane toad problem cannot be dealt with.
