This book is simpy outstanding. Few books can rival the wide scope offered by Animal on a vast range of organisms which include invertebrates, birds, reptiles, mammals, fish, and amphibians. The book is adorned with magnificent color photos of each organism and a compact description that provides adequate amounts of info on the organism. Although some common species are excluded, it more than makes up for this with the amount of species covered. For every common species excluded, I ran across three new species I had never heard of. This book is an extraordinary guide to the vast array of wildlife in the world. There are few books that I have found as informative and enjoyable to read as Animal. It truly is a definitive guide to the world's wildlife and I highly recommend it.
