The results of the present study are showed three types of fauna, the biggest numbers of fauna belong to Ostracods. The other fauna are represented in type of algae (Charophyta) and one genus of Gastropods. The SEM analysis indicated that the organisms are affected with water lake chemistry, the element S exists in the wall of Charophyta and Ostracoda, while the gastropods does not contain this element. They concluded that these organisms were affected with the salinity except gastropods genus which transport by bird feet from Caspian Sea.
