Book excerpt: Whales are awe-inspiring creatures. They move their gigantic bodies through water gracefully. But some of these majestic marine animals have an odd way of protecting themselves from bloodthirsty sharks and other predators. They can create a cloud of waste, or poop, to hide in or to confuse their pursuer. While that's amazing, perhaps it's even more incredible that one kind of whale poop is so valuable it's called "floating gold"! Readers will love all these facts and more in this fun, accessible book about these beautiful mammals.
