Fish 

Dive into a watery world where many wonderful fish of all shapes and sizes swim, in rivers, lakes, and oceans.
Eyewitness Fish is an exciting and informative guide to the fascinating world of fish. Striking colour 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, and why fish need water to breathe, and much more.
Part of DK“s best-selling Eyewitness series, which is now getting an exciting makeover, this popular title has been reinvigorated for the next generation of information-seekers and stay-at-home explorers, with a fresh new look, new photographs, updated information, and a new ‚eyewitness feature – fascinating first-hand accounts from experts in the field.
