After sections on "A Mammal's Body" and "Mammals' Milk," each group of mammals is described in turn. Odd mammals, such as Pangolins, that do not belong in any of the standard groups are featured on their own in a section at the end. A glossary and an index conclude the book.

Although obvious care has been taken to be precise and factual, the text does occasionally overgeneralize. For example, at one point, there is a sentence: "Mammals have hair or fur on their body." The error in this sentence is accentuated as it appears above a picture of a hairless Orca.

All the pictures are captioned, with the unfortunate exception of a two-page spread of a leopard. Since many readers may not be familiar with the appearance of some of the larger cats, this omission could be an annoyance. In general, however, this is a wonderful book, both well illustrated and organized.

Recommended.
