Octopus!: The Most Mysterious Creature in the Sea by Katherine Harmon Courage
Octopus! is a fascinating exploration that is less about the creature itself (the plural of which we are told not more than a few pages in, is octopuses because of the word’s Greek origin, not octopi) as it is humanity’s relation with it. The book begins with a look at how these creatures are caught and from then goes on to examine everything from the role of the octopus in our cuisine to how the organism is informing studies of camouflage, robotics, and artificial intelligence. A large portion of the work is about those who are working to understand the cephalopod’s physiology—from the fluid mechanics of how it jets around in water to the distributed intelligence that likely helps control its arms to how cells in its skin detect the surrounding conditions and allow it to camouflage itself so quickly (not simply changing color but also texture and even the polarization of reflected light).
All of this means that as much as Courage wants us to take the octopus on its own terms, throughout the book the animal is continually seen through the lens of its relationship (and usefulness) to humans. In this respect, the title needs the exclamation point, because despite the fascinating topic, the book itself reads at times like an extended Scientific American article, or a series of these articles put together (and it did, admittedly, start as something like that): a ride-along on an octopus fishing boat, a visit to a robotics lab on the Italian coast or an octopus-processing plant in NYC, complete with a cascading cast of experts and scientists who add their perspective to the author’s account. It makes for a lot of information but not necessarily a cohesive narrative.
Besides the octopus and our interactions with it (on boat, plate, and lab) the book lacks an organizing or overarching theme. We’re not given a clear picture of Courage’s own story regarding the subject: how did she develop such an interest in the octopus that she was driven to seek out experts around the world? This might have helped tie things together, if the author herself played a larger role in the narrative. Courage’s writing style was also at times uneven, moving abruptly from expert scientific exposition (which was usually clear and sharp and detailed, as when, for instance, she offers an extensive discussion of editing in the octopus gene sequence) to random allusions of octopus depictions in comics, pop culture, horror films, and even erotica. A more structured discussion of any of these topics would have added to the treatment, but presented as they were without context or discussion (at times it seemed just for comedic effect) they seemed abrupt or even jarring. Despite these flaws, the book was rich with fascinating detail regarding these amazing invertebrates.
