To Gauge Distance, Jumping Spiders See Green (5 of 7) (VIDEO)
Caption
This movie shows the jumps of two jumping spiders under green and red light. Under green light, the spiders made accurate jumps. In contrast, under red light, the jumps were short, and some spiders failed to catch their targets with the first jumps. This video relates to a paper that appeared in the Jan. 27, 2012, issue of Science, published by AAAS. The paper, by T. Nagata at Osaka City University in Osaka, Japan, and colleagues, was titled, “Depth Perception from Image Defocus in a Jumping Spider.”
