Abstract: Ciliate protozoans are considered as the dominant protistan group in the interstitial system of marine sediments. They play an important role in the processes and evolution of the benthic ecosystem (Fenchel, 1966; Sorokin, 1999). Therefore, a great attention has been paid to the distribution of interstitial ciliates in sediments of coastal and estuarine environments throughout the world (Faure-Fremiet, 1950; Dragesco, 1960, 1963 a,b; Fenchel, 1969 ; Wilbert and Kahan, 1981; Ricci et al., 1982; Al-Rasheid, 1992 ; Santangelo and Lucchesi, 1992; El-Serehy, 1993; Al-Rasheid and Sleigh, 1995 ). Along the Red Sea especially the Saudi coast, there is little information about the marine ciliate distribution and their relationship with the environmental factors. Wilbert and Kahan (1981) recorded 16 species of benthic ciliates from the Solar lake of the Gulf of Aqaba. While, El-Serehy (1993) found 13 Sand – dwelling ciliates at the Great Bitter lake along the Suez Canal. In addition, Al-Rasheid (2001) reported 18 species along the Saudi coast of the red sea. The present study was conducted to increase our knowledge of the interstitial ciliate populations along the Saudi coast of the Red Sea. The benthic ciliate Protozoans from Obhor Alshimaliyah and Obhor Aljanubiyah were collected to give a clear picture of the taxonomic structure diversity and biomass in the different analyzed micro-communities. Temperature, pH, Salinity and Organic matter were measured directly at the water \ sediment interface in order to characterize the main environmental features that related to the distribution of ciliates.
