My youngest son loves books about animals, and this one is no exception. The photographs are bright and professional. The information provided is great for younger readers or about first level readers. He feels the book has just the right amount of facts for early readers. I like the layout and colorful pages. We both agree older readers might still like to look through the book but they would need a more thorough book to learn more. We received this book through a giveaway. No compensation has been or will be received in exchange for this review.
