Eight-eyed jumping spiders have a near 360-degree view of the world, according to a new study that also found these spiders can be captivated by humans and nature videos.
The study, published in the latest Royal Society Biology Letters, presents a detailed look at how each of these spiders' eight eyes works. During the experiments, the researchers also discovered that the spiders sometimes become fixated on certain nature videos, as well as people.
"Whereas many spiders, like black widows or the brown recluse, tend to avoid people, jumping spiders often seem quite fearless," co-author Elizabeth Jakob told Discovery News. "I doubt that they mistake large objects, such as people, as prey, but they are certainly interested to know whether you pose a threat.
Jumping spiders not only have keen vision, but also a gregarious nature and a seemingly insatiable curiosity about humans and nearly everything else.
"If a spider turns to look at you, it is almost certainly a jumping spider," Jakob said, adding that they respond to their own mirror images and watch videos showing insects.
When shown videos of moving crickets, the spiders will attack the screen. Jakob said you "can hear the click of their fangs on the screen" as they try to chomp the virtual insects. In the wild, they stalk prey "much like a cat stalks a mouse, following it and tackling it."

I feel sorry for the arachnophobes, They are really missing out. I currently have about a 6 larger spiders here living free of charge in the house for the winter. 2 Jumping Spiders, and 4 Orb Weavers. They are great to have in here. They take care of all kinds of troublesome insects over the winter. They are happy in here. Jumping spiders in particular are vary entertaining. Orb Weavers are like a lazy dog, Eat and rest. Jumping spiders are quite active and give hours of entertainment. All are friendly.
