The savage creatures eat anything - including people
- but that didn't stop danger-mad pensioner Janet Martyn, 73, stepping into a metal cage and looking three of them in the eye at a South African nature reserve.
Janet has been a volunteer at the Cango Wildlife Ranch for several years and luckily the three crocodiles - called Hannibal, Marbaker and Sue - recognised her and, instead of attacking the cage and trying to take chunks out of her, gave it a friendly nuzzle.
Separated from certain death only by a metal grill, a thrill-seeking pensioner comes face-to-face with one of the most dangerous creatures on earth.
Lowered into the water in a cage, danger-mad 73-year-old Janet Martyn, from Walthamstow, London, is a matter of inches away from three deadly, 12-foot long Nile crocodiles.
While brave Janet was getting her bearings in the water in the Cango Wildlife Ranch in South Africa, the animals began circling her, and would normally have been licking their lips at the prospect of a hearty meal.
But the crocs, named Hannibal, Marbaker and Sue, recognised Jan as a familiar face - and, instead of trying to take chunks out of her, began playfully nuzzling her cage.
