Overview

The björntrattspindel (Coelotes atropos) is a medium-sized funnel-web spider with a dark brown to blackish coloration and robust build. This species constructs distinctive funnel-shaped webs in crevices and plays an important role as a predator of small invertebrates in its ecosystem.

Björntrattspindel (Coelotes atropos) faces significant threats from habitat degradation and fragmentation of its specialized cave and underground environments. Climate change poses additional risks by altering the delicate microclimate conditions essential for this species' survival, while human disturbance of cave systems further compounds population pressures.
