This book reveals the world of the underwater kingdom where sharks have ruled for millions of years. In unique photographs, outlandish marine creatures will appear before you as living. Consider them in detail! You will see: the monstrous mouth of a man-eating shark, the birth of a shark cub, the eyes of sharks during the hours of rest and at the minute of attack, a bearded fish. You will learn: how to escape from a shark on the high seas, where they find "mermaid wallets," how a sea angel differs from a sea devil, how a shark perceives the world around it. You will understand: why does the shark need a sixth sense, like a hammerhead fish looking for prey, why the sea fox has a long tail, why sharks need to be saved and much, much more.
