"Living things come in all shapes and sizes. The animal kingdom is vast, and scientists have separated organisms into groups based on different shared characteristics. What makes animals different from each other? What traits do they have that overlap? Through this engaging book, readers learn all the biological differences that help animals survive and thrive in the wild. Pictograms and infographics make digesting this scientific information easy, and readers who struggle to obtain information from traditional textbooks will find this book especially helpful."--Publisher.
