Thwaitesia argentiopunctata known as the sequined spider, mirror spider, or twin-peaked Thwaitesia, is a species of spider found in almost all states of Australia. It is known to have a reflective abdomen that plays a crucial role in their camouflage to protect them from predators in the forest canopy. The scales look like solid pieces of mirror glued to the spider's back, but they can actually change size depending on how threatened the spider feels. The reflective scales are composed of reflective guanine, which these and other spiders use to give themselves color. [A-Z Animals: Sequined Spider]
