This book is really awesome! I thought that because my kids and I already know a fair amount about mammals, that we wouldn't get much out of it....but I was WRONG!
They detail many different types of mammals: monotremes, marsupials, placentals, primates, rodents, lagomorphs, carnivores, insectivores, perissodactyls, artiodactyls, edentates, sirenians, cetaceans, and more! Fascinating stuff! Short info to just capture your interest and not bore you with too much detail.
