Communication is considered a fundamental process in everyones life, and its not exclusive to human beings; animals communicate too and they do it in different ways, depending on what kind of message they want to portrait and the species that they belong to. Visual, bodily, olfactory, tactile and other signs are used by animals to transmit courtship messages, predator danger warnings, callings to locate members of the pack, among many others. How they occur, how they learn, how they differentiate from others, are some of the questions that this book talks about to awake the curiosity of small readers.
