    From the thread on astrobiological arXiv papers comes this thread:

    Could an alien have the equivalent of a human eye that covers its entire body?

    Well, you have heat sensors all over your body as a human, which isn't quite the same but can start the issue. I'm trying not to think of a creature like the mythological giant Argus, covered with real eyes. An undersea creature could have pressure sensors all over, so it picks up indications of nearby creatures.

    (art, not mine, shows Hera ordering Argus to guard a white heifer)

    Oh hey, that’s from the D'aulaires' book!
    The greatest journey of all time, for all to see
    Every mission makes our dreams reality
    And our destiny begins with you and me
    Through all space and time, the achievement of mankind
    As we sail the sea of discovery, on heroes’ wings we fly!
