I have to share a youtube of a particularly well-photographed jumping spider. In general jumping spiders are common and there are over 5000 species. They don't build webs instead preferring to hunt and pounce, indicating better than average vision and learning abilities since it requires some judgement on the risk taken for pouncing on something out of your league. They only use a silk-line as a safety mechanism in case they miss and fall.
Not as "leggy" as other spider groups, I have always appreciated this segment of the population as uncharacteristically animated, curious and ... just ...cool-looking with a streamline, compact and unusually articulate shape. They can in fact appear as though they are turning their head, since they have up to a 40 degree range of motion on the front half of their body.

More often than not, if I offer a finger, my subject of interest will hop from their perch to see what they can see by sitting on my hand. That's just charming, if you can get over the initial spideriness of it all.
