Nematomorphs are free-living as adults but parasitic on arthropods as juveniles. They are commonly known as horsehair worms or gordian worms. They have a unique life cycle where they lay their eggs in water, and the larvae infect and develop inside the host arthropods. Once they mature, they emerge from the host and become free-living adults.
