Jumping spider
Because they have good vision, jumping spiders can see human beings when they approach. Some jumping spiders may run away from approaching humans, and some do not. But either way a jumping spider will watch a nearby human being. When they do not run away, but do turn to keep watch over a human being, it may seem that they are interested in us. Some of them will even jump from where they are sitting on branches, rocks, etc. onto a person's finger or camera. These spiders only bite to get something to eat or to defend themselves, so if they jump on somebody's hand they will not bite. People might get bitten if they pinch or squeeze a jumping spider.
