Alien benthic foraminiferal assemblages of Samandag and Yayladagı coasts (Hatay, Turkey) have been investigated. 41 genera and 58 species of benthic foraminifers were identified and Indo-Pacific originated alien species were found to dominate the foraminiferal assemblage. Pararotalia calcariformata which shows distribution in the western Pacific is recorded for the first time in the Mediterranean Sea.
