Zim Fish have lived on the Earth far longer than any other backboned animal. This book is an introduction to the world of fishes, a guide to their habits, anatomy, evolutionary history, diversity and relationships with each other and with man. 278 of the most common fresh- and salt-water fish have been beautifully captured in the exquisite illustrations. A number of interesting rarities are noted for good measure. Includes some animals mistaken for fish, additional sources of information, scientific names and an index.
