Sometimes big nerdiness comes in a small package—and this little book is an animal nerd's dream! Meet animals of all kinds—from sharks and moles to orangutans and okapis— in this quirky, jam-packed original from National Geographic Kids. If you thought you were brainy, take a look at the incredible critters in this book. Inside, you'll find a spider that spends its whole life in a bubble and birds that build nests so big, they're like avian apartment complexes! (And we're just getting started!) In this little animal "Nerdlet" you'll learn about the weirdest, coolest, most amazing creatures in the animal kingdom—and what makes them so complex. Plus, you'll have some of your most burning animal questions answered, such as What's the deal with crocodile tears? And you'll meet people who get to be around animals for a living and travel to animal destinations around the world. You'll also find personality quizzes, fun facts, animal superheroes, and even a Star Wars reference ... or two.
