This comprehensive atlas brings together for the first time in a single reference work a vast amount of information on the distribution and characteristics of all the major freshwater fish families of the world. Distribution maps are given for each family, along with discussions of size, evolution, life habits, social and ecological significance, and other data pertinent to the families. Line drawings are included to aid in the identification of fishes, and the text is supplemented with a glossary, pronunciation guides, and suggestions for further reading. Designed for professionals and neophytes alike, this compendium will serve as a valuable guide for ichthyologists, biogeographers, aquarists, and fish hobbyists. -- from back cover.
