The book is filled with all sorts of cool facts that even an adult might like to read. Big pictures and bubbles of information keep each page interesting and bright. The animal facts range from the ordinary to the really weird. For example, you've heard of a Wallaby? It's like a mini kangaroo. According to the book, a Wallaby can't hop backwards. Very interesting and doesn't make much sense, but there you have it.
I sat down to read this book with my kids but soon realized that they're too young. My five year old enjoyed some of it, but mostly they looked at the pictures then jumped up to play. I do think this book would be ideal for someone in middle school or towards the end of elementary school. A curious child who enjoys reading would probably like this book a lot.
The book also came with a cool DVD of bloopers from Jack Hanna's television show. It didn't come out of the package easily though, so be careful. It was pretty sticky.
This is a cute book and fun to read.
