Essai sur la logique de l'imaginaire
I am studying octopuses at the moment, and that means also learning about their cousins, including cuttlefish. This is Pfeffer's Flamboyant Cuttlefish.
I knew before that cephalapods cannot see colours (although they can perceive polarized light), but I did not know that the lenses of their eyes are "pulled around by reshaping the entire eye" in order to change focus.
(This post is headed with the subtitle of the book on the octopus by Roger Caillois)
