s are members of the family Salticidae
. They have the best eyesight
of all spiders, with four big eye
s on the front of their head that make them look almost like a Toyota Land Cruiser
. The other four eyes are smaller and are on the back of their head. Their excellent eyesight is used to stalk
, spotting unsuspecting insect
s from up to a couple of feet away, then pouncing
on them like a cat
If you see a spider that has noticed you and is turning its head to watch you, it is probably a jumping spider.
Since jumping spiders catch their prey by hunting, they don't need webs to do that job. The webs they build are instead used for shelter, and are often a crude lean-to placed in a crack of a building.
Salticids have interesting and elaborate courtship dances, in which the male raises his front legs and waves them in precise ways to attract females. This sort of courtship display wouldn't work in species with poor vision.
