This 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 or the nests, known as 'redds', created by the tails of breeding trout. Profiled species are illustrated with detailed colour artworks, and there are maps and quick-reference data panels to pinpoint distribution, habitat, food, size and breeding habits.
