Life cycle

Philometridae cycle between two hosts: Cyclopoida (small crustaceans) as an intermediate host, and various fish as a definitive host. [2] First-stage larvae are ejected into the water, and develop to the third stage if they're eaten by a cyclopoid. Once the copepod is eaten by a fish, the larvae develop into adults and mate. Pregnant females migrate to a final site just under the fish's skin, in the swim bladder, or in the coelom; males die soon after mating and in many Philometridae species they have never been described.
