As saltwater crocodiles stalk Australia's waterways, we investigate if they should be culled to curb attacks on humans.
Heralded as the 'animal most likely to eat a human', saltwater crocodiles are a common feature in Australia's tropical north. The ancient predator is the world's largest reptile, growing up to seven metres long and weighing more than a tonne.
Once endangered due to commercial hunting, their numbers had dropped dramatically to just 3,000. However, following the introduction of protection laws in 1971, this steadily increased, with scientists now estimating their population at more than 100,000.
