About the book: 1964 / The famous three-eyed tuatara lizard lives on the rocky islands of New Zealand. This animal is more ancient than brontosaurs, ichthyosaurs, diplodocus and other extinct giant lizards. Tuataras originated 200 million years ago from the first reptiles. This amazing creature, reaching 75 centimeters in length, is “friends” with the petrel and lives with it in the same hole! The author of the book, a biologist, fascinatingly talks about how spiders dance in the spring, scorpions and snakes, how mosquitoes and bees “talk”, and about other amazing adaptations, habits and instincts of the animal world associated with mutual assistance. Using interesting facts, the author convincingly proves the complete inconsistency of the Malthusian statement about the right of the strong to live at the expense of the weak, as if predetermined by the development of nature.
