I picked this up at a local Borders on sale for $10. Being an animal lover and enthusiast, I figured what the hay. After looking it over, I realized the fish family isn't covered in the book. Which is kind of a downer but not a major gripe.
The book is pretty good and covers a lot of species of animals. Problem is, the descriptions of most, if not all, of the animals is around 2-3 small paragraphs at most. It's not an extensive encyclopedia or a book that goes into great detail; just enough to cover the usuals of each animal.
All in all, not a bad book but if you're looking for an in-depth book, this isn't going to be what you're looking for.
