Who has nine brains, three hearts, and can use tools? In this engaging new science book, aimed at children from 7-12, you will be introduced to some of the ocean’s most fascinating creatures, the octopuses. Learn how the common octopus fades into its background. Find out why the mimic octopus impersonates a fish. Discover how the amazing eyes of octopus mean that they can understand colour – even though they are colour-blind. There is more than just biology here. In the second part of the book, be guided through life as an octopus, finding out what they eat, where they live, how they mate, and whether octopuses really build cities. At the end, learn what the different threats are to these incredible animals, and how we can protect them as our oceans change.
