Octopuses are practically alien. They can: - shape shift into so many different forms and shapes. - "invisibility", by instantanously changing colors & it's own skin texture, to match surrounds. - can regrow entire body parts if cut off (like arms) - have 9 brains (localized) - and are ridiculous intelligent

And yet like us they have two eyes. I wonder if we meet aliens from another star-orbiting planet if their light-sensors will look anything like ours.

  Well, I'm not sure there'd be much benefit to spending energy on a 3rd eye. You can already achieve stereoscopic vision with just two eyes, why waste the energy on a third? It probably doesn't increase fitness enough to be worth the energy spend.

    It might be too hard to parse, but an eye on each arm would give variable baseline and potentially 360° stereoscopic coverage.

    Yet some creatures have many more than two eyes. Spiders, for example.

      Those are not eyes though. Animals eyes always come in a pair and whether it’s a human, dog, cat, mouse etc they are Gods gateway to the soul. It’s self evident.

And they might have dreams! One of the coolest things I've encountered at an aquarium was a sleeping octopus wildly shifting its colors. It seems truly alien to behold -- like it shouldn't be possible. My googling after the fact says that who knows why they actually do it or what's going on, but, I really like the thought of them having little octopus dreams.
