This beautifully illustrated encyclopedic directory contains detailed facts about many of the wonderful and varied fish, reptiles and amphibians that dwell in the world's freshwater habitats. More than 450 of the creatures that inhabit rivers, streams, swamps and lakes are profiled in detailed entries. Creatures are grouped with close relatives, to enable the reader to compare or distinguish between similar-looking species. Learn intriguing facts about morphology and behaviour: the brilliant flashes of colour borne by breeding males; the nests, known as 'redds', created by the tails of breeding trout; or the fleshy tentacles that assist the foraging of benthic catfish and barbells. Profiled species are illustrated with superb, detailed colour artworks, and there are maps and quick-reference data panels to pinpoint distribution, habitat, food, size and breeding habits. With over 500 stunning illustrations and photographs, this information-packed directory will appeal to anglers and aquarium enthusiasts as well as to the general reader.
