Arachnophobia is a prevalent fear in modern society, and the stunningly effective camouflaging ability of the world’s collective spider population is just one more reason to embrace your irrational arachnid fear. Spiders come in a myriad of sizes, shapes, and danger levels, but some of their most effective variations are outfitted with camouflage that can conceal them in forest branches, rainforest leaf bundles, and colorful flowers. Many spiders have developed bizarre striping or dotting patterns to dissuade larger predators, but others have become masters of embracing their own smallness and swift design, content to lie in wait in bushes or rocks for their next victim. So far, science has not been able to uncover a spider that blends in perfectly with the color of bedroom walls and is able to vanish in an instant, but there’s a strong argument to be made for this breed’s existence.
