    the way the rods and cones are arranged in the octopus' eyes seem to be an adaptation for night vision (or underwater vision in general) so I would guess the same goes for the cuttlefish.

    Generally they have no use for farsightedness underwater, especially in the depths.

    Mimicry is something else. I'll be looking into this more before diarying on it since it is spectacular the way these animals are able to imitate their surroundings and it's way beyond me to know offhand how they do it.
