     Let's face it. Even as babies, we humans pay close attention to faces. Observing another person's features and expressions tells us whether they are happy, angry, excited, or sad. And when we look at an animal, it's hard not to imagine that its face is communicating human feelings. This isn't true, of course. Squinty eyes, an upturned mouth, or another odd expression is probably there because, in some way, it helps that animal survive.      Packed with many cool facts and visuals on where certain animals live and what they eat, this book captures twenty-five humorous—and very true—explanations of why animals look the way they do in order to exist in this world.
