This book was released on 2016-06-26 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Pygidiidae, a Family of South American Catfishes The Pygidiidce are a family of South American catfishes distinguished exter nally by the absence of an adipose fin and by the posterior position of the dorsal. Most of them are even more readily distinguished by the presence of spines or thorns on the opercle and interopercle, by twin barbels at the angle of the mouth, and by the absence of all mental barbels. Other characters of the catfishes may be present or absent, and by addition, subtraction, or modification of characters, various subfamilies have been formed. A description of the characteristic strue tures is given on pages 276-279. The basal habit of all the members of the family is that of burrowing. The opercular and interopercular spines are an adaptation to their habit of insinuation, which is at the root of the commensalism, parasitism, and worse, to which some highly specialized members of the family are addicted.

This book was released on 2017-12-11 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Amazon and Orinoco basins in northern South America are home to the highest concentration of freshwater fish species on earth, with more than 3,000 species allotted to 564 genera. Amazonian fishes include piranhas, electric eels, freshwater stingrays, a myriad of beautiful small-bodied tetras and catfishes, and the largest scaled freshwater fish in the world, the pirarucu. Field Guide to the Fishes of the Amazon, Orinoco, and Guianas provides descriptions and identification keys for all the known genera of fishes that inhabit Greater Amazonia, a vast and still mostly remote region of tropical rainforests, seasonally flooded savannas, and meandering lowland rivers. The guide’s contributors include more than fifty expert scientists. They summarize the current state of knowledge on the taxonomy, species richness, and ecology of these fish groups, and provide references to relevant literature for species-level identifications. This richly illustrated guide contains 700 detailed drawings, 190 color photos, and 500 distribution maps, which cover all genera. An extensive and illustrated glossary helps readers with the identification keys. The first complete overview of the fish diversity in the Amazon, Orinoco, and Guianas, this comprehensive guide is essential for anyone interested in the freshwater life inhabiting this part of the world. First complete overview of the fish diversity in the Amazon and Orinoco basins Contributors include more than fifty experts Identification keys and distribution maps for all genera 190 stunning color photos 700 detailed line drawings Extensive and illustrated glossary

Download or read book Freshwater Fish Distribution written by Tim M. Berra and published by University of Chicago Press. This book was released on 2008-09-15 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Distribution,maps the 169 fish families that swim in fresh water around the world. Each family account includes the class, subclass, and order; a pronunciation guide to the family name; life cycle information; and interesting natural history facts. Each account is illustrated, many with historical nineteenth-century woodcuts. Now available in paperback, this heavily cited work in ichthyology and biogeography will serve as a reference for students, a research support for professors, and a helpful guide to tropical fish hobbyists and anglers.
