Monogeneans, members of the class Monogenea, are a group of ectoparasitic flatworms commonly found on the skin, gills, or fins of fish. They have a direct lifecycle and do not require an intermediate host. Adults are hermaphrodites, meaning they have both male and female reproductive structures.
Protomicrocotylidae is a family of monogenean parasites in the order Mazocraeidea.
Lethacotyle vera is a species of monogenean of the family Protomicrocotylidae.
Discocotyle sagittata is a species of freshwater monogenean gill ectoparasites of Salmo and Oncorhynchus. Their lifestyle is characterised by a free-living larval stage that may be inhaled by a suitable freshwater fish host, after which they may attach upon expulsion over the gill onto a single gill filament. Upon reaching maturity, parasites can remain attached by a posterior opisthaptor with its 8 associated clamps. Adults may reach a few millimetres in length. D. sagittata feeds on the blood of the gills via an anterior mouth part. Adults are hermaphrodite, and produce 3–14 eggs per day at 13 °C, a process which is temperature dependent. Once produced, eggs drop to the riverbed surface and at 13 °C take 28 days to develop to hatching larval forms. Major parasite burden can result in damage to the host gill and anaemia from blood loss.
