A delightfully silly and informative picture book from the author of Animal Zombies & Other Real-Life Monsters . Grown-ups expect kids to avoid all sorts of "rude" behaviors. But in nature, spits, burps, and toots can happen for surprisingly strategic reasons. When animals exhibit every gross habit--from toxic sneezes to deadly farts-- they're not aiming to act rude. They do what they can to survive. This book features the most dazzlingly disgusting creatures on planet Earth--indecent insects, repulsive reptiles, cute-yet-crude mammals, and more. You'll also hear from scientists who are investigating what humans can learn from these bold behaviors. Prepare to be gobsmacked by good reasons for rudeness.
