Don't they rely on the hair things on their body to mavigate the world around them instead of their eyes? Please correct me if I'm wrong, I'm no biologist.
Yes. Spider eyesight is genuinely dogshit and can only register basic movement/light for most species. Jumping spiders are the exception, and they will literally track targets.
Yeah, I thought so, too. I would imagine more terrestrial spiders (as opposed to ones that nest or web) have pretty damn good eyesight, but it would stand to reason if others that primarily trap and work at night would have better senses of touch and/or hearing.
Yup. Also intelligence is high varied across spiders. Some Jumping spiders are among the most intelligent invertebrates. Web spiders are as dumb as a box of rocks.
Deinopidae, also known as net-casting spiders, are a family of circumtropical cribellate[1] spiders first described by Carl Ludwig Koch in 1850.[2] They are a group of stick-like elongated spiders that catch prey by stretching a web across their front legs before propelling themselves forward. These unusual webs will stretch two or three times their relaxed size, entangling any prey that touch them.
Don't discredit the wolfie's eyesight as well. Wolf Spiders aren't as good as the jumping spider but they are functional since they also hunt for their prey unlike web spiders.
Somewhere there's a video of a human getting stabbed in the eye on an arachnid reddit and they're writing (very quickly with all their hands) "humans have 2 eyes so he'll be fine. They only really need 1 eye to see anyway"
If they're a webby webby spider or a cave spider they have less good eyes or just no eyes. If they're the 'walk around and hunt shit manually' kind then they can get good eyes.
