The zebra back spider (Salticus scenicus) is a common jumping spider of the Northern Hemisphere. Like other jumping spiders, it does not build a web. It uses its four pairs of large eyes to locate prey and its jumping ability to pounce and capture it. Zebra spiders are often noted for their awareness of humans. Upon noticing someone observing them, they can be seen raising their head, and usually change behavior (hence the name Salticus scenicus, theatrical jumper).
