The eggs of oviparous forms frequently have one or more polar filaments that may serve to anchor them in the gill mucous until a young adult hatches, with the haptoral sclerites already well formed. The eggs of oviparous Gyrodactylidae have a drop of cement on the tip of a short filament that is used to “glue” the egg on the external surface of their hosts. Viviparous gyrodactylids give birth to complete worms, which already carry an offspring in the uterus when born. According to HARRIS (1983), Oogyrodactylus farlowellae can complete its cycle from egg to adult in 11 to 13 days at 27 °C.
