[2] Over much of its range Solea aegyptiaca is sympatric with the rather similar common sole and has been considered a subspecies by some authors in the past.

It is however more closely related to the east Mediterranean Senegalese sole (Solea senegalensis) than it is to the common sole, and where these two species' ranges meet there is a hybrid zone, with hybrids being detected from the Gulf of Lions and the coats of Tunisia as demonstrated in the research of Dr. Khaled Ouanes.

[3] S. senegalensis is thought to have invaded the Mediterranean from the eastern Atlantic through the Straits of Gibraltar, a phenomenon knows as Herculean migration after the Pillars of Hercules.

[4] Solea aegyptiaca is a benthic demersal species that lives on soft mud and sand substrates in coastal and littoral waters and in brackish lagoons,[1] down to 100m in depth.

[6] Solea aegyptiaca feeds on benthic invertebrates, mainly Cnidaria, polychaete worms and bivalves.

[8] Solea aegyptiaca is a commercially important flatfish species in the Mediterranean waters of Egypt where it is fished by bottom trawls .
