Giant communal spider web discovered in dark cave

Scientists found a giant communal spider web in a dark cave housing 110,000 spiders.

Why it matters

  • First instance of cooperative living and colonial web-building in spiders.
  • Unique ecosystem driven by chemosynthesis, not sunlight.

By the numbers

  • 110,000 spiders: 69,000 Tegenaria domestica and 42,000 Prinerigone vagans.
  • Web surface area: 106 sq m (1,141 sq ft).

The big picture

  • Spiders adapted to a dark, sulfuric cave environment, evolving unique behaviors.
  • Ecosystem relies on sulfur-oxidizing bacteria for energy.

What they're saying

  • Users fascinated by chemosynthesis-driven ecosystems.
  • Jokes about avoiding the cave location.

Caveats

  • Findings based on a single cave ecosystem.

What’s next

  • Further genetic studies on isolated spider populations.
