Researchers have determined that the spiders use these reflective areas to scatter light in order to evade predation, making it difficult for other animals to see them. These glimmering splotches are most likely crystalline deposits comprised of guanine. Spiders are generally renowned for their camouflage capabilities, highlighted by the diversity of species that are capable of changing color. Some are even able to contract their guanine sequin spots.
