Spiders are generally hated by people. We’re afraid of them because of stories about the venomous ones.
Actually, there is a special family of spiders, which is named Salticidae. Those are jumping spiders. They are very special. They have an advantage of 140 billion years of evolution from “bird eaters.
I have some „bird eaters” also known in English as „tarantulas” and I can say that they are a way less intelligent than jumping spiders. They are almost blind, can recognize only the day or the night. They use hearing to hunt. Their logic is all about: I hear a prey, I hunt the prey, eat it and that’s all. Jumping spiders have eyes that are very unique. They use them to hunt the prey… But before, they make a glorious plan of „HOW TO DO IT?”, „FROM WHERE SHOULD I ATTACK?”, „IS IT SAVE FOR ME?”.
A group of engineers made a test on a jumping spider. Phidippus Audax were used in this test. Please watch the video and answer the questions below:

1. What happened when a fly was shown to the spider? Do you think that jumping spiders due to their evolution are kind of intelligent?
2. What is the resolution of jumping spider’s eyes and why do they need so many of them?
3. Are you afraid of spiders? Share your thoughts about spiders at all :)

If I understood correctly, their brain activity increases once they see a fly. I don't know if we should call them intelligent, it is rather their instinct, but I must admit that they are one of the most intelligent among spiders (I've heard that Portia fimbriata is the most intelligent one).
2. What is the resolution of jumping spider’s eyes and why do they need so many of them?
Resolution of jumping spider's eyes is almost the same as human eye resolution, they use lateral eyes to sense the motion of an object (for example fly) and its principle eyes to gauge depth.
3. Are you afraid of spiders?
No, I'm not afraid of spiders, this type presented by you is even kind of cute though I hate snakes and it is not that I am afraid of them, they are simply disgusting.
2. Their resolution is almost the same as in humans, but a bit less. Each pair of eyes is responsible for different functionality, for example, extreme lateral eyes are responsible for determining the movement of an object.
3. No, I am not afraid of spiders, I consider them very cute insects.
Each is from something else, some sideways from the change of surroundings, and the main from observing the whole surroundings, certainly the amount of eyes helps them in catching the victims.
Not necessarily, spiders in Poland do not bite fatally so there is nothing to be afraid of; p
I don't like spiders, maybe I'm not afraid of them, but I just don't like how they look - they disgust me a bit. So they are not welcome in my house. ;P But if they for example make a web outside my window, I consider it somehow useful, especially during summer. ;)
They seem to act rather on instincts. The nature has surely created them well suited to the predator role.
2.What is the resolution of jumping spider’s eyes and why do they need so many of them?
It allows them to spot motion around them and gauge the distance so that they can perform an accurate attack.

I don’t think that people are afraid of spiders as they are. We simply seem to be scared of what we don’t know. Due to their, for some, not attractive appearance most of the people is not really into deepening their knowledge and understanding of spiders, therefore simply claim to be scared of them.
I must say, that looking at the huntings is satisfying :)
For the whole live I was scared too :/ But as we're scared about something we can cure from it with shock. :D Going to some events with "bird eaters" and taking a big spider on hand with a companion of a experienced guy can cure arachnophobia in second :)
These spiders have eye resolution comparable to ours so they have amazing eyesight. When hunting it can be one of the most reliable methods that will allow for such long-term survival of such an advanced species.
My fear of spiders depends on the situation. If I do not expect a spider then I can be very scared but if I know that a meeting can take place with him, I accept it with calmness.
But I must admit, this species of spiders are pretty cute. While separated from me by glass or screen, of course. I would not say that their ability to jump makes them smarter than their fellows, rather, this is a new step of evolution. It definitely helps them to eat. It is very cruel on the part of men to poke a needle in a spider with a needle, even it became a pity. One thing is instant death from a boot, and quite another to mock it (
