Majority of the alien foraminifers recorded in the eastern Mediterranean are Indo-Pacific originatedand entered the Mediterranean via Suez Canal. In this study, current literature on the alien benthicforaminiferal fauna of the eastern Mediterranean was reviewed and the main dispersal pathways aredetermined. Distribution patterns of the alien species suggests that most of the species are introducedvia Suez Canal and expand their range of distributions in a counter-clockwise manner by the generalsurface currents of the eastern Mediterranean. However, not all, but some of the species have alsobeen dispersed westwards along the North African coast and reached central Mediterranean.Locally abundant records of Euthymonacha polita (Chapman), Coscinospira acicularis (Batsch)and Amphistegina lobifera in the Aegean Sea indicates that Suez Canal may not be the only vectorfor the Indo-Pacific species to enter eastern Mediterranean and submarine springs help thesethermophilic species to form establish populations in cool waters of the northern Aegean and the Seaof Marmara
