Once Cy Montgomery, the author of this book, stroked an octopus in an aquarium - and fell madly in love with these animals. Octopuses are intelligent and inquisitive, and their nervous system is so different from ours that we still don't know exactly how it works. The author tells about the various stages of the life of octopuses, relying on special literature, conversations with researchers and her own experience of communicating with these unique animals - first in an oceanarium, and then in the natural environment.
