During the hunt, velvet worms use their oncopods to grip and immobilize their prey, and they employ their powerful jaws to pierce and inject toxic venom into the unfortunate victim. The venom serves to paralyze and subdue the prey, making it easier for the velvet worm to consume it.
Velvet worms play an important ecological role as predators within their respective ecosystems, contributing to the regulation of invertebrate populations and maintaining the ecological balance.
