Abstract :Benthic foraminifer assemblages of the Turkish Aegean coasts have been investigated. Sediment samples from Alibe and Maden Islands insert ignore into journalissuearticles values(Balıkesir);, Kusadası insert ignore into journalissuearticles values(Aydın);, Cesme Ilıca Bay insert ignore into journalissuearticles values(Izmir); and northwestern coast of Karaburun Peninsula insert ignore into journalissuearticles values(Izmir); have been analysed. Similarities, as well as dissimilarities were observed between the assemblages from different locations. The Red Sea orginated alien foraminifer Amphistegina lobifera Larsen was found to form a very dense population around the south and west part of a submarine spring water in Kusadası, where as it was replaced by Ammonia compacta Cushman and Elphidium crispum insert ignore into journalissuearticles values(Linné); assemblages on the northern and eastern parts. Euthymonacha polita insert ignore into journalissuearticles values(Chapman); has been first recorded in Kusadası and it is also abundant in the Ilıca Bay. The Red Sea originated Coscinospira acicularis insert ignore into journalissuearticles values(Batsch); has also been first recorded in the Mediterranean from Ilıca Bay. Presence of the individuals with colored tests indicates the presence of heavy metals in spring waters. Aberrant aperture morphologies observed in some of the Vertebralina striata d’Orbigny individuals attracts attention. Abundance of individuals with colored tests, morphological deformities or togetherness, as well as the Red Sea originated species indicates the special environmental and ecological conditions around the submarine springs.
