A book from the series "100 Greats" tells about records in the world of wildlife. A significant part of the phenomena of wildlife, the characteristics of the life and behavior of the inhabitants of the land and the oceans, simple and complex organisms have long been studied and described by scientists. Nevertheless, plants, invertebrates, fish, amphibians and reptiles, birds and animals never cease to amaze and delight us with their properties. And if you try to build a kind of rating of their records and achievements, then sometimes even familiar representatives of flora and fauna begin to look like unique creatures of the Creator. The longest algae and tallest tree, the largest and rarest beetle and the largest fish, the most "hardened" bird and the rarest mammal on Earth - these and many other "record holders" pass through the pages of the collection.
