Where did the Flying Dutchman come from? What's really going on in the Bermuda Triangle? Where did the missing ships go? Where are the mysterious islands? More than 70 percent of the Earth's surface is occupied by the oceans. Life originated here, thanks to the ocean it exists. Despite this, modern scientists know much less about the underwater world than about deep space. Literally every minute the ocean throws us new riddles. Most of them remain unsolved, but for centuries they excite the imagination of researchers and fiction writers who ask eternal questions. You will find answers to some of them in the new book by Vlad Vilenov.
