The jumping spider family (Salticidae) contains more than 500 described genera and about 5,000 described species, making it the largest family of spiders with about 13% of all species. Jumping spiders have good vision and use it for hunting and navigating. They are capable of jumping from place to place, secured by a silk tether (you can see it). Jumping spiders are known for their curiosity. If approached by a human hand, instead of scuttling away to safety as most spiders do, the jumping spider will usually leap and turn to face the hand. Further approach may result in the spider jumping backwards while still facing the hand. The tiny creature will even raise its forelimbs and hold its ground. It may even jump on the hand. Because of this contrast to other arachnids, the jumping spider is regarded as inquisitive as it is seemingly interested in whatever approaches it. This little guy jumped at my camera a few times. It was a neat experience. Every time I pointed the camera at him, he turned and challenged it. I took this in my back yard in Rockaway, NJ. I used a Nikon Coolpix L110 digital camera.
