Cephlapods are interesting and often overlooked in the intelligence department. This book mainly focuses on the octopus - evolution, nervous system, behaviour, memory, their skin and how and why they change colour. There are some funny stories along the way as well as some cool pictures. I definitely enjoyed my time in Octopolis where octopuses hang out, mate, fight and eat scallops.
It was also interesting to read about how the first living things lived during the Ediacaran period and how things evolved and came to be what they are today. As the book went on I found it a bit repetitious and boring as some things did not tie in with cephalopods. Once I got a taste of octopus that was all I wanted. But still an enjoyable read overall.
