A jumping spider is black, and the spot on its back is often white. However, some of these spiders have an orange mark instead of a white one. Jumping spiders frequently have black-and-white striping on their legs that helps camouflage them against trees.
Jumping spiders are found worldwide, but most are located in tropical regions. These spiders also live in prairies, grasslands, fields, barns and houses. Jumping spiders are not dangerous to humans, although their bite is painful. Certain types of jumping spiders have red undersides.
Jumping spiders earn their name from their ability to leap relatively great distances — they jump up to 25 times their own height. This is a great advantage when they hunt for food.
