With more than 29,000 species, fishes are the most diverse group of vertebrates on the planet. Of that number, more than 12,000 species are found in freshwater ecosystems, which occupy less than 1 percent of the Earth’s surface and contain only 2.4 percent of plant and animal species. But, on a hectare-for-hectare basis, freshwater ecosystems are richer in species than more extensive terrestrial and marine habitats. Examination of the distribution patterns of fishes in these fresh waters reveals much about continental movements and climate changes and has long been critical to biogeographical studies and research in ecology and evolution. Tim Berra’s seminal resource, Freshwater Fish Dis...
Among all vertebrates, gobies are second in diversity only to the teleost family Cyprinidae. The Gobiidae consists of more than 200 genera and nearly 2,000 species and make up the largest family of marine fishes. Gobies account for as much as 50% of the energy flow in coral reef communities. Their small size, ability to adapt to numerous ecological

Winner of the PROSE Award for Best Single Volume Reference in Science by the Association of American Publishers Unique among the world's fishes, frogfishes display a bizarre combination of attributes and behaviors that make them a subject of fervent study. Through cunning and trickery, they turn would-be predators into prey; they "walk" across the ocean floor and jet-propel through open water; some lay their eggs in a floating mucoid mass, while others employ complex patterns of parental care; and they are certainly among the most colorful of nature's productions. In Frogfishes, two of the world's leading ang...
