Ever look in the mirror the first thing in the morning and say I look like a crap While for some spiders, looking like poop can actually be a life saver, because masquerading as a bird toes appears to protect certain eragnite from getting eaten by wasps².That's according to a study in the journal Natural scientific Reports.Researchers were over the plentiful³ bird do their and forest in Taiwan. Then they realized that some of those dropping were in fact special spiders sitting in the top silky white disks at centre of their web. Sure this

scatological costume may fool a bunch of PhD, but do the predatory wasp¹ for fooled to find out. The researchers used spectrometer to confirm the spider in the web is especial inextinguishable from bird's bread. Then they changed the the covering of some webs by dusting them with carbon powder，and they found that spiders that rest on the artificially black and silk were much more likely to get eaten. Now this result don't prove that wasps buy the whole put ，maybe spider against the white background are just harder to spot, to be more confident that looking like poops is key，researchers may test the wasps to found out if they are just glimpse it and stepping it.
