Researchers identify over 111,000 spiders in what may be the world's largest spiderweb in Sulfur Cave on the Albanian-Greek border.
The web spans 1,140 square feet and is formed by barn funnel weavers Tegenaria domestica and Prinerigone vagans.
The web was first discovered by cavers in 2022.
The sulfur-rich diet has produced genetic differences from outside populations, prompting scientists to call for preserving the ecosystem amid cross-border challenges.
