In this book, I present 30 animals. I chose five points to communicate information about each animal in order to identify each one without seeing it. First, I selected the description of the animal to explain which animal it is or where its geographical area is. Next, I selected the diet to explain the migrations and the different behaviors which are related to the diet. This includes finding food sources, conditions, the lifecycle of the animal in the sense that it is related to its reproduction. Wolves, for example, do not reproduce enough—or not at all—when game is lacking. That is why I selected the third point, the lifecycle of animals to show how they reproduce. What are the seasons when this breeding takes place? What is their lifespan compared to others? Finally, I selected their mode of communication, which includes, among other things, the behavior during the mating season. For the most part, the calls that these animals emit have various reasons.

The purpose of this book is to allow those who do not have the time, the intellectual capacity, or the physical capacity to carry out research to study a book or a website, to go to a zoo or aquariums to see animals, or to be able to recognize an animal even by the cry of it. I therefore focused on the sound insertion of the cries of animals that have one alive in support of the other information. In other words, in addition to the description of the animals, their food, their lifecycle, and their mode of communication, one or more vocalizations of these animals have been included.
