In a pitch-black cave along the border of Greek and Albania, researchers discovered a 1,140-square-foot spider web that houses two spider species — an unprecedented example of cohabitation.

Arachnophobes beware: Scientists have discovered the world’s largest spider web in a pitch-black cave along the Albanian-Greek border.

This “extraordinary” — and frankly horrifying — web stretches a staggering 1,140 square feet and houses more than 110,000 arachnids of two different species.

In a study recently published in the journal Subterranean Biology , researchers noted that these particular spiders are not typically social creatures. As such, this discovery may also be the first example of the two arachnid species forming a colony.
