South American rats settle arguments by boxing. Tuna fish sunbathe and herring communicate with each other by breaking wind. Llamas hum to each other, elephants impersonate traffic sounds and whales sing ballads. Some kangaroos grow on trees.Strange new, scientifically proven facts about the animal kingdom emerge seemingly every day. Here, gathered together in one book, are hundreds of the funniest, most fascinating and plain bizarre things we have discovered about the non-human world.All animal life is here: from the only dog that can develop gout to the wren whose song sounds just like Beethoven, from the cattle that generate electricity to the worm that has the power to brainwash. It is a book full of surprises. Who would have thought giraffes can't trot, reindeer 'fly' after taking magic mushrooms or that elk turn nasty when drunk? Who would have known that shark embryos attack, that caterpillars tap dance or that - out of our earshot - male mice are serenading their girlfriends with high-pitched love songs? And who on earth would have guessed that male pandas court potential partners by performing handstands?

And...

Dolphins can bray like donkeys. Frogs can growl like gorillas. Bears, wombats, dogs and snakes snore.

Or...

Flies sumo-wrestle. Squirrels kick sand in rattlesnakes' faces. Bees roast their victims alive.
