What new species of spiders have been found in Greece?
Scientists have discovered two spider species, Tegenaria domestica and Prinerigone vagans, living together in a massive web inside a sulfur cave on the Greece-Albania border. These species are usually solitary, making their coexistence in this environment particularly unusual.
-
How do these spiders survive in sulfur caves?
The spiders survive by feeding on cave midges and microbes that thrive in the sulfur-rich environment. Their adaptation to such extreme conditions demonstrates their resilience and ability to exploit unique food sources in dark, toxic caves.
-
What does this discovery tell us about cave ecosystems?
This discovery highlights the complexity and adaptability of cave ecosystems. It shows that even in harsh, sulfur-laden environments, diverse and thriving communities of organisms can exist, challenging previous assumptions about subterranean life.
-
Are there other hidden caves with unique wildlife?
Yes, many caves around the world remain unexplored and could host other undiscovered species. These hidden environments are crucial for understanding biodiversity and the evolution of life in isolated habitats.
-
Why is the size of the web significant?
The web spans over 1,140 square feet and hosts around 111,000 spiders, which is extraordinary for such a habitat. Its size indicates a highly successful and stable population, providing insights into social behavior and adaptation among normally solitary spiders.

What are the ecological implications of this discovery?
This finding suggests that extreme environments like sulfur caves can support complex ecosystems. It also raises questions about how species adapt genetically over time to survive in isolated, toxic habitats, offering new avenues for ecological and evolutionary research.
