Life Cycle: C. diversus species have a direct lifecycle. Hermaphroditic adults of the Ancyrocephalidae family are attached to the gills of fish and produce eggs that are expelled into the water column and attach or mucus or organic material. From here, the eggs hatch and the larvae attach to a new host and develop into the adult phase (Reed et al., 2012).
