Description:My son loved learning about so many animals. We did not expect this book to be all-encompassing, and I also noticed some discrepancies, life the life expectancies of the animals on a chart didn't all match up with another book I saw, but at that age level we were happy, lots of pictures to keep them interested and the vocabulary was at my son's level, he really enjoyed and we went through this book quickly, unlike some of the other "complete books".
