A swim in waters teeming with hippos and crocodiles is not for the faint-hearted ... but for Swaziland's Royal Jozini Game Reserve's general manager Jay Azran, concern for the world's rhinos trumped all the fear. 

To raise money for an anti-poaching cause, Azran decided to take his chances and swim 2.5 kilometres across Jozini Dam (which borders Swaziland and South Africa). Not only did the life-threatening feat push his personal limits to the max, but it also did some serious good for rhino conservation. Watch!
