A Good Judge of Distance Jumping spiders actively pursue their prey, often jumping relatively long distances in order to catch them. Such feats require accurate depth perception. Nagata et al. (p. 469; see the Perspective by Herberstein and Kemp) show that jumping spiders use a process called image defocus, which allows depth perception to be obtained through the comparison of a nonfocused image to a focused image within the same eye. A single layer within the spider's eye that could not focus… Expand
