Velvet worms possess a unique hunting mechanism utilizing a "slime cannon" that fires protein-based liquid threads. These threads rapidly transform into sticky, elastic fibers upon ejection due to mechanical stress and environmental changes. This biological innovation allows the slow-moving worms to ensnare small arthropod prey and deter predators by creating adhesive traps. AI
