Abstract EN

Seven different regions were chosen in southern Iraq and were represented by the marshes of three governorates, which are Basrah Governorate (Al-Qurna, Al-Jawaber, Al-Huwair (Izz Al-Din Salim District), Al-Madina District), Maysan Governorate (Al-Uzair District), and Dhi Qar Governorate (Al-Jabayish District and Al-Hammar Marshlands) for the period from October 6, 2019 to February 24, 2020.

Ten genera of modern mollusks were classified Actaeon, Corbicula Littorina, Lucina, Murex Pholadomya, Planorbis, Turritella, Venus, Viviparus, of which belong to the Pelecypoda group of modern mollusks, and other genera belong to the Gastropoda group, The prevalence of these races in general varied in all areas of the study.

The races of the two-foot axes (Corbicula Littorina, Lucina, Venus, Pholadomya) were the common ones, while the other races of the ventral foot were of limited spread.

The genus Murex is in the marshes of Dhi-Qar governorate and was not found in the marshes of other governorates due to transport factors.

This genrus bears high salinity, while the environment of the marshes (Brackish water) is characterized by the genus Murex spreading in the Shatt al-Basrah channel, as well as the high salinity in Um-Qasr area.
