"#cephalopods, like #cuttlefish, have the ability to perceive the polarization of light. If some light waves are oriented vertically and others are oriented horizontally, cuttlefish differentiate these in a similar way that humans might differentiate blue and red light."

Guide to Squid, Cuttlefish and Octopuses of Australasia by Mark Norman & Amanda Reid, 2020
The Australasian region is home to the greatest diversity of cephalopods — squid, cuttlefish, octopuses — in the world. Yet, we know very little about these fascinating marine animals. This book provides insights into the biology and behaviour of more than 60 species.
From the Giant Squid to the deadly Blue-ringed Octopus, the secret lives of cephalopods are revealed in a highly readable form with outstanding colour images and informative text. For each species there is a distribution map and identification notes which summarise the main features to look for. While the book focuses on species found in relatively shallow coastal waters, a few of the more bizarre deeper-water species are included. Naturalists, divers, reef-walkers and anglers will find the book authoritative, yet very easy to use. A comprehensive section illustrating cuttlebones will enable beachcombers to identify most of the species they are likely to encounter.
