Story summary
  • Researchers documented a colony in Sulfur Cave on the Albania-Greece border covering 1,140 square feet and housing about 111,000 spiders, published in Subterranean Biology.
  • The colony includes two species, Tegenaria domestica and Prinerigone vagans.
  • This marks the first documented case of colonial behavior among these typically solitary spiders.
  • The cave's hydrogen sulfide-rich environment creates extreme conditions.
  • The ecosystem relies on chemoautotrophic bacteria forming a distinct food chain independent of sunlight.
