Abstract
A total of 36 mollusk species were encountered along the western coast of Libya between Gout Alruman and Tellil. Samples were collected during September and October 2004 using a 25× 25 cm quadrate on a sectorial belt. Gastropods were the most dominant class with 25 species followed by Bivalvia (10 species) and one species of Polyplacophora. No significant differences in number of molluscan species were recorded between locations. The results showed clear variations in the number of benthic animals in all studied stations which ranged between 136–7276 individuals.
