World\'s Largest Spiderweb Discovered

Scientists have uncovered a jaw-dropping marvel in a sulfur cave along the Albania-Greece border — the world’s largest spiderweb, sprawling across an astonishing 106 m². Even more incredible, over 111,000 spiders from two species that usually compete for territory are coexisting peacefully within this vast, shimmering network. Researchers say it’s the first known example of rival spider species forming a self-sustaining “super-colony,” where cooperation, not competition, keeps the delicate ecosystem alive.
