A 1,140-square-foot spider web in a Greek-Albanian cave hosts 110,000 spiders of two species living peacefully due to abundant food and darkness.
A massive 1,140-square-foot spider web has been discovered in Sulfur Cave on the Greek-Albanian border, hosting an estimated 110,000 spiders from two species—Tegenaria domestica and Prinerigone vagans—in an unprecedented peaceful coexistence.
Scientists were surprised by the lack of aggression between the larger and smaller spiders, which typically prey on one another.
Researchers believe an abundant food supply of around 2.4 million midge flies, combined with constant darkness limiting vision and promoting reliance on vibratory cues, reduces competition and conflict.
The cave-dwelling spiders show genetic differences from surface-dwelling relatives, indicating adaptation to the stable, sulfur-rich environment.
While web-building may be collaborative, there is no evidence of cooperation in hunting or caring for young.
The discovery, published in Subterranean Biology, offers rare insight into how environmental stability and ample resources can foster long-term communal living among typically solitary spiders, likened to humans sharing a building without direct interaction.
