A solid little book that pacts a reasonable amount of information into the constraints of an early reader, clearly outlining the distinguishing characteristics between two easily confused animal groups.  Before reading this, I couldn’t have told you what the difference was, but now I know.  The book addresses traits such as size, tails, noses, family behavior, and intelligence.  It also offers a map showing regions in which both types of animals live, and discusses the relationship both have to humans as fellow primates.  It’s got a solid binding, all the usual non-fiction text features, and color illustrations that support the text.
