This is an automatically translated description
The author suggests this book for use both in a Waldorf school and in the family, and he primarily takes into account the needs of 10-12 year olds, but experience shows that interest in it is not limited to age.
Since this is a book for reading, not a textbook, the choice of animals and their sequence is entirely arbitrary; what is common is the style in which, without falsely humanising the animal, an attempt is made to describe it in such a way that the reader can feel: now I understand it.
