Here is an exciting and informative guide to the fascinating world of fish. Striking color photographs of tropical fish, eels, seahorses, and more offer a unique "eyewitness" view of the natural history of fish, how they behave and how they survive. See the lethal jaws of a piranha, a porcupine fish "puffing up," how a dogfish swims, growth rings on a fish scale, what a fish looked like 400 million years ago, and a fish with legs. Learn how a school stays together, why some fish swim upside down, how a stingray stings, which male fish can "give birth," how stickleback builds its nest, and why fish need water to breathe. Discover why a shark must keep swimming, how a ray can give an electric shock, what eyespots are for, how an archerfish "shoots" a victim, and much, much more!
