Octopuses, squids, cuttlefishes and their relatives ("cephalopods") are some of the most "alien" creatures on earth.
They have complex behaviours and many are experts at spectacular colour and shape changes. They come in all shapes and sizes, from pygmy octopuses to giant squids measuring more than 15 metres long, and occur from shallow reefs to the deep sea.
This 320 page guide includes information and photographs of species from around the world as well as stories on their unique lives and bizarre habits. |
