 Wpf Media-Live Photos 000 261 Cache Huge-Spider-Webs-Kid 26176 600X450 This massive spider web in Madagascar was woven by Darwin's bark spider, a recently-discovered arachnid that uses its incredibly-strong silk, ten times tougter than Kevlar, to make the world's largest webs. These spiders are known to make orb webs in Andasibe-Mantadia National Park up to 2.8 meters square anchored by 25-meter threads.
