Harvestman, or Daddy Longlegs, is a small eight-legged animal related to the spiders. It lives in temperate and tropical regions. There are over 3,200 species, 200 of which are native to the United States. Unlike a spider, a harvestman has long, stiltlike legs and a segmented abdomen, and lacks silk glands. The legs each have seven joints, making them highly flexible and allowing the animal to run rapidly over leaves and grass.
