Entobdella soleae
Entobdella soleae is a monogenean (Platyhelminth) skin parasite of the common sole, Solea solea, an important food fish. They are approximately 2 to 6 mm in length. It is flat, translucent, and has a large, disc-shaped haptor, a posterior organ used for semi-permanent attachment to the host. Typically, 2-6 parasites are found on wild sole, but in intensive fish farms this can rise to 200-300 parasites per fish, causing skin inflammation and sometimes death of the sole. E. soleae can live up to 120 days in seawater.

What it does
The life cycle of Entobdella soleae follows the life patterns of their marine bottom-living host. The Solea solea would bury itself in the sediment for some time each day. The parasites are attached to the bottom of their host, in which when their hosts bury themselves, the parasite lays their eggs. The eggs are anchored to the sea bottom so that they wouldn't be swept away by the water currents. When the eggs hatched the oncomiracidia emerges and invades the anterior part of the upper surface of the fish. This part of the fish is the only part that is exposed when the fish is buried. After entering and developing on the upper surface of the fish, it migrates down toward the lower surface of the fish where they reach sexual maturity. Adult parasite would distribute throughout the lower surface of the host and are oriented with the adhesive organ upstream.
