    spiders are freaks.
    pic is a whip spider (not a spider) that has more ancestral form of the eye arrangement.
    I guess a spider's sight gives a modded sense of it.

    Is anyone able to imagine having an eye far away from their brain, say if it was on your foot? I'm having difficulty with that. Having your thoughts and your sight in separate places.

      Yeah, that's weird. I feel like my head is the part of the body that I'm actually "in," since I both see and think from there. But then, the Ancient Egyptians thought it's the heart that thinks.

      Maybe play with some drones or one of those small cameras on a long wire. You adapt pretty quick.
      There’s a interesting experiment where they wore special goggles that show you everything upside down; eventually, your brain just interprets the image as right side up and that’s what you see.

      I would look up the process of cephalization in evolutionary biology.
      The brain tends to develop as close to the sense organs as possible because it cuts down on the lag since impulses don't travel down nerves as fast as you think (you've probably driven faster in a car). When you need that information to eat or not be eaten it benefits if you have eyes and a brain or ganglia nearby so you can react as quickly as possible (or a nose or ears or whatever you like).
      Your brain uses a lot of tricks to edit out this lag to your conscious mind, touch your finger on one hand to the tip of your nose, and on the other hand touch the tip of your toe at the same time.
      It FEELS like its all happening instantly despite the fact that there's about a fifth of a second difference in the time it takes both signals to reach your brain.
      What happens is that your brain knows to account for this difference, and gives the signals the same timestamp despite them hitting at different times, and so it FEELS like it happened at the same time. One of the possible explanations of Deja Vous is that the filing clerk in your brain fucks up and gives something the wrong timestamp. You're just sitting there and thinking of a song, but some aspect of that moving out of iconic memory (super short term memory, a buffer or cache for your brain) into more permanent memory gets flagged as happening "some time ago" instead of "right now" and the best your brain can do to cope is go "DUDE THIS HAPPENED BEFORE! HOW WEIRD" because a big part of human perception is making sure no one ever looks behind the curtain and realizes how little we deal with reality and how much of our experience is an ad hoc subjective hallucination that probably resembles an objective reality.

    It's like how almost every new smartphone has 3 or more front cameras.

    Depends on the species.
    If its just a web spinner they don't have very complex eyes and are only good at seeing brightness and movement.
    There are exceptions like jumping spiders, who can see almost 360 degrees in stereo, because they need to be able to navigate in complex three dimensional spaces.
    Some spiders that hunt have good eyes. Bird catching spiders have good enough eyes to snatch a small bird out of the air.
    They have brains built around taking in that sensory input and creative an image of the world.

      Every species of spider that can even remotely attempt to catch a bird has terrible eyesight

    same way you do

    not only do you have 2 eyes working to make one image, but each eye has almost 100 million individual cells that each work as an eye and all that information is combined in the brain.

        true, I'm making assumptions.
        sorry about that.

        if your eyes don't work that way you have my sympathies

      so is their depth perception better than ours?

        doubtful, they probably can't focus nearly as far as we can. Up close probably, but at small scales they're better than us at almost everything because they're tiny.

      It depends on the spider, actually.
      Here's how a jumping spider sees.

      Spiders don't have compound eyes

        Nobody said that. He’s referring to the light sensitive cells of your retina
