About the Holiday
This United Nations-sponsored holiday was established in 2013 to celebrate the world’s wild animals and plants and to raise awareness of the perils they face. Since that time, World Wildlife Day has grown to be the most important global event dedicated to wildlife. This year’s theme is “Big cats: predators under threat.” The big cats are some of nature’s most majestic animals, and they are now being threatened by habitat destruction, declining prey populations, conflicts with people, poaching, and illegal trade. It is up to us to protect the animals that share our planet. To commemorate today’s holiday, learn more about the world’s creatures and consider donating to a wildlife cause.

Book of Bones: 10 Record-Breaking Animals
Written by Gabrielle Balkan | Illustrated by Sam Brewster
When you think about bones, you know a lot, right? You know they’re hard and not soft, you know they form your skeleton and that they come in different sizes and various shapes, and you know that all vertebrates have them. But have you ever wondered “which animal has the biggest bone in the world? Or the smallest, Or the spikiest?” Well, you’re about to find out thanks to this big book all about bones.
So, let’s get started! About that biggest bone…would you like to take a guess who it belongs to? Here are some clues: This mandible bone “is a whopping 20 feet long. That means three motorcycles could sit in a row” on it. The animal it belongs to lives in the ocean, swims great distances, and “can live for 100 years.” Just take a look at the skeleton on the next page with one long spine, two flippers, fifteen pairs of ribs and a huge skull. Good guess! Let’s turn the page and see… Yes, it is a Blue Whale!
Now that you know, you can learn more about the blue whale—like how its mouth is so big that you and one hundred of your friends could fit on its tongue, how it eats 700,000 krill in one gulp, and slurps down 40,000,000 krill every day! Go ahead—touch the illustration of the whale. Feel all of those bones?
Ready for another one? Okay! We did the biggest, how about the smallest bones? Here are some clues from the animal herself: “I am teeny tiny. My skull is smaller than your pinky nail….Inside my ears are the smallest bones in the world: my hammer, anvil, and stirrup bones,” which are about the size of a • . You’d find this animal on farms, in gardens and in olive groves, and even though it’s small, its bite is poisonous. But you’d have to look very closely to find it because its skeleton is “the size of a paperclip and weighs less than a single raisin. What is it? The Etruscan Shrew! You can pet it to feel its bones—this one isn’t venomous.
Imagine if your bones were as thin as a strand of spaghetti. It might make lifting heavy boxes and throwing baseballs or running on the playground pretty hard, if not impossible. But for this next animal having such thin bones is just right. Let’s see if you can guess what it is from these clues: “I sleep upside down, snuggled with my family. I flit through cool limestone caves. I am an amazing flyer…but can’t walk very well.” You know it—it’s a bumblebee bat!
This bat is as small as its namesake, and its thin finger bones support its wings. “If your finger bones were as long and thin as [the bumblebee bat’s], your pinky would be as thin as a strand of hair and keep going past your toes!”
This is fun! How about another? Guess who has the spikiest bones? You’d find these bones covered with keratin on top of the animal’s head to protect its brain—and to keep it from being eaten by snakes or coyotes or other predators. This animal lives in the deserts of Arizona, eats ants, and…can shoot stinky blood from its eyes when threatened! What is it? It’s a Regal Horned Lizard! Now, feel those spiky horns and all of the rib bones that make this lizard so round.
You’re a great guesser! So try them all—there are a lot more animals to discover and fascinating facts to learn in this book! No bones about it! You’ll find out more about the Reticulated Python, Reticulated Giraffe, African Bush Elephant, Peregrine Falcon, Alaska Moose, and Hammerhead Shark. At the end, there’s also a Glossary of Bone Words for you to bone up on!
Gabrielle Balkan makes learning about the ten animals Book of Bones exciting by including the kinds of facts that kids find most eye-popping and eww-inspiring described in ways that they can relate to. Comparing the size of an animal to a paperclip or the thickness of a bone to a strand of spaghetti creates an immediate visual that makes budding scientists want to learn more. Balkan’s conversational style lends a personal touch to the text—as if the reader is interacting with a wildlife expert one-on-one.
Opening the oversized Book of Bones is like walking into a natural history museum where skeleton exhibits stand side by side with natural habitat dioramas. Sam Brewster introduces each animal with accurately drawn skeletons on black backgrounds that let readers see the placement of each bone. Special features are called out in a whisper of gray, adding to the museum display feel. Turning the page allows children to see each animal in its vibrant, natural habitat. Ingenious printing lets readers feel and see the rough bones beneath the skin.
A fun, fact-filled resource for nature lovers, Book of Bones: 10 Record-Breaking Animals would make a great gift and addition to classroom, school library, public library, and home bookshelves.
