Hippos may make you laugh, but watch out! Acclaimed naturalist Jonathan London takes an exuberant look at these massive, swift and dangerous animals. What's the deadliest animal in Africa? It's not the lion or the crocodile - it's the hippo! They have razor-sharp tusks, weigh as much as fifty men, and can run twenty-five miles per hour! Follow these hefty hulks as they glide underwater, play tug-of-war, swat balls of dung at one another and nuzzle their young in the mud. Just don't get too close - they could chomp you in two! Jonathan London's unique blend of stroytelling and facts is brilliantly matched in Matthew Trueman's wonderfully entertaining illustrations.
