Here is an original and exciting new look at the fascinating natural world of ponds and rivers. Stunning real-life photographs of fish, water beetles, frogs, underwater weeds and more offer a unique "eyewitness" view of the natural history of plants and animals that live in and around freshwater habitats. See how a trout develops from its egg, how a dragonfly nymph changes into a dragonfly, what plants look like under the water, and how waterbirds camouflage themselves. Learn how a dragonfly nymph catches its food, why a caddis fly makes a case from sticks and shells, why kingfisher eggs have no camouflage markings. Discover how to distinguish the difference between toad spawn and frog spawn, how underwater nests are made, how a salmon climbs a weir, which insect can walk on water, and much, much more. - from Amzon
