This comprehensive encyclopedia explores how the inhabitants of these waters shape their existence - from navigation and hearing to feeding hierarchies and courtship rituals. Artworks of basic habitants draw out the families likely to live in each one. The major part of the book consists of illustrated continental directories on key freshwater families - hundreds of bony fish, as well as turtles, newts, crocodiles, and others. All creatures are grouped by family and genus, to expose connections between similar species, and help the reader tell them apart. With over 1000 glorious colour images overall, this information-packed resource will appeal to anglers, aquarium enthusiasts and budding biologists alike.
