I have been hearing very good reviews about this Animal Series from Reaktion Books, but I must say that the first one I've read is a slight disappointment.
It has interesting bits (I loved everything about early scientists), but the whole thing is too anthropocentric for my liking.
First of all, the actual idea for the book: apart from the physiology bits, the rest of the chapters are about man's interactions with the animal. I didn't mind the chapter about fishing, as you learn how political it all is and how humans don't miss many chances to prove how ruthless and brainless then can be, but I could have done without the chapter on eating octopus. Not interested at all and, in the end, it's just the same thing over and over again.
Some of the biology is also too anthropocentric for me: even if we ignore the talks about 'intelligence' (I still can't understand why scientists are happy applying parameters for human intelligence to animals, instead of looking at it from the point of view of each species, but hey, I think that battle is lost); anyway, even if we ignore that, the fact that he repeatedly talks about how 'octopuses look back at you' really irritated me. He says that when you look at an octopus you can see that there is an intelligent being behind those eyes. Well, how can he not consider that perhaps he's thinking that because octopuses have exactly the same type of eyes as humans? It's obvious that we are always going to have some sort of connection with a being that shares some physiological trait with us, but that does not mean that reptiles, for example, who have a different type of eyes, are not intelligent!
It's not that I could have written a better book, but almost. Still, an interesting read, if only for the anecdotes. I wanted more literary and art references, though: more about the impact octopuses have on humans, more than the other way round.
