An interdisciplinary team of researchers from Spain and Croatia led an investigation into the peculiar lifestyle of numerous spider species, which live, feed, breed and ‘walk’ in an upside-down hanging position. According to their results, such ‘unconventional’ enterprise drives a shape in spiders that confers high energy efficiency, as in oscillatory pendulums. These results will appear in this week’s issue of PLoS ONE.
