Battle of the Jaws: A massive crocodile and a protective mother hippopotamus lock jaws in a titanic battle in the Shire River, in the Liwonde National Park, Malawi. The reptile burst out of the shallows, jaws open, lunging towards a hippo and her calf. At first it looked like the reptile had the upper hand, but the hippo sent the scaly intruder packing bloodied and bruised. (By ARNAUD GERMAIN )
