Check Out 'Spider City,' The Largest Spider Web Ever Found

Spelunkers found a giant spider 'super-city' in a cave on the border of Greece and Albania. The massive webbed structure, in the depths of the Sulfur Cave, is over 100 square meters, consisting of thousands of funnel-shaped webs. The lead researcher studying the arachnid habitat says it's likely the largest spider web in the world. Scientists say it's home to an estimated 11,000 spiders, from two different species, including the barn funnel weaver.
