      Interesting. Purely anecdotally, when I tried setting up experimental work
      with dolphins in the early 70s, mirrors were the only things (other than
      cattle-prods - which somebody else was responsible for using on them) that
      got the 3 I knew really annoyed. Our then on-the-fly rationalisation was
      that this was because we had shown them 'ghosts': their sonar told them it
      was a wall; their vision gave them an image.

      However, it was intuitively clear that there was 'someone in there', more
      dramatically clear than in my concurrent and subsequent face-to-face
      dealings with orangs, gorillas and Kanzi, Panbaneesha, et al. So,
      intuitively, they may well be able to do this. From an evolutionary
      perspective, why the heck c/would they have built the machinery to
      underwrite it?
