A lucky hyena narrowly escaped being eaten by an angry hippo - that it mistook for being dead.<br /><br />Safari guide Carlos Ismail was leading a tour in Ngorongoro Crater, Tanzania, when he spotted an opportunistic scavenger wading through some water.<br /><br />Tense footage shows the hyena creeping up on the behind of a seemingly immobile hippo half submerged under the algae.<br /><br />Suddenly the hyena turned tail and just in time as the hippo swung its huge body around and chased it from the water almost catching it in its powerful jaws.<br /><br />Carlos said: “This hyena was very lucky. It was on its own and I think it thought that the hippo was dead and would be an easy meal.<br /><br />“It just managed to escape in time before it was caught in the hippo’s huge jaws. It barely managed to make it to dry land.<br /><br />“I have been a guide now for nine years and have never seen anything like this before. Although I have seen the same hippo chase after a lioness.<br /><br />“They are not scared of anything!”<br /><br />The footage was filmed on November 1 last year.
