Our planet is home to a huge number of species of animals, plants, fungi and bacteria - so huge that science has not yet been able to count them all. And it will probably take a long time to count. Every year, biologists discover a new monkey, a previously unknown palm tree, or some microscopic fungus. Plus, many people believe that the planet is inhabited by lizards, huge furry primates, and even dragons. This book tells about the most incredible secrets of living beings and organisms - secrets not only real, but also imagined. Petr Obraztsov is a writer, science journalist, author of many popular science books.
