@photostoryclub: At the border between Albania and Greece, the largest spider web in the world was discovered — it is home to over 111,000 spiders. The "spider megapolis" is located deep inside a sulfur cave and features a network of thousands of webs extending along the walls over an area of about 106 m². Interestingly, the colony hosts two species — Tegenaria domestica and Prinerigone vagans. This marks the first known scientific case of their cohabitation (usually, the former preys on the latter).
