Find out all this and more in World Book’s World of Animals!

World Book's extraordinary educational app gives kids of all ages plenty of opportunities to explore, compare, rank, and quiz themselves on their favorite animals. This interactive app features hundreds of stunning pictures, videos and animal sounds, quick facts, encyclopedia articles, a captivating educational game, and more!

World of Animals excites learners with fun, factual information and rich multimedia on their favorite animals, from monkeys, giraffes, and penguins, to lesser-known creatures including axolotls, sugar gliders, and wetas. Not to mention prehistoric animals and dinosaurs!

Kids can browse the stunning gallery of animals, search for animals by name, or filter their favorites by category. Each animal gets its own profile page, featuring multimedia and quick facts about the animal's habitat, size, diet, lifespan, and conservation status along with fun facts, such as a honey bee's “waggle dance,” the length of time a cockroach can live without its head, and what makes a flamingo chick's gray feathers turn pink.

What's the difference between an alligator and a crocodile? A gorilla and an orangutan? What about a tiger and a saber-toothed cat? Kids take their understanding of animals further by analyzing the differences and similarities between animal species using the World of Animals' simple but powerful compare tool.

Which animals can live more than 100 years? What animal moves even slower than a tortoise? What is the largest animal that has ever lived? (Hint: It's not a dinosaur!) Rank animals to see how they stack up against each other in terms of weight, height, length, lifespan, land speed, and more. Order the animals from highest to lowest (or lowest to highest) and link back to the animal's profile for more information.

So now that you're an animal expert, find out how much you've learned by playing the entertaining "Guess Who!" game that highlights more than 500 animal facts.

Kids of all ages will be captivated by the World of Animals' fascinating array of information, dazzling images and videos, interactive compare and rank tools, and a game that's as fun as it is educational. Try it today!

World Book's World of Animals

My 5 year old granddaughter loves this app. I purchased the extra animals, but well worth the money.

Great app!

I downloaded this on a rec from a social network site, and I am very impressed.
The facts are easy to read, there is a lot of information presented colorfully and accurately.
I have played the fact game a few times, and I am surprised at how little I know about animals. My 6 loves it, my 14 year old won't admit to liking it (he does), and I love it for them.
I have found one identification mistake, but other than that, great job, World Book Encyclopedia!

Amazing App!

This is a superbly done app with a wealth of information, photos, and -- best of all -- videos! My 4-year-old grandson loves looking for his favorite animals, watching the videos, and especially hearing the animal sounds. I like how World Book has made learning a side effect of having fun. The dinosaur videos are great! The best part is this app is suitable for kids of all ages, as well as adults.
