This wonderful and colorful book goes straight to the source to find out what is up with some of the oddest features of animals. Each page asks an animal about one of its well know features. For instance, the mandrill is asked why his nose is so colorful, and the puffer fish is asked if he is about to explode. Each animal gives a short response as to why they are the way they are. As usual, Steve Jenkins has put forth some incredible illustrations. They are bright, they are fun, and they are super interesting. The facts are also all of these things. This is a great way to introduce kids to the idea that all living creatures have traits that help us survive.
