Gunung Kidul is one of the districts in Yogyakarta province that has a long coastline with a substrate of coral (rocky shores) and white sand. One of the beaches with rocky substrate is Indrayanti. The rocky substrates are different from other substrate which have physicochemical factors changes in water and gives its own character for the life of marine organism in intertidal zone. Mollusca as one of the phylum that live mostly in the marine and some are in intertidal zone of marine with coral substrates. This aim of the research to identification the types of mollusca that found in the intertidal zone of the Indrayanti and classifying each species found. This research method by observation and data collection techniques by accidental sampling during low tide. The data in this research are qualitative data that analyzed by descriptive. The result of this research shows that the mollusca phylum which inhabited the intertidal zone of the Indrayanti beach found 4 classes from 7 classes in Mollusca phylum, there are gastropoda, bivalvia, polyplacophora, and cephalopoda classes with a total amount of 83 species. Gastropoda class that dominate of all species are about 69 species or 83,13%, with the most subclass order are caenogastropoda, heterobranchia, patellogastropoda, vetigastropoda and neritimorpha. Polyplacophora class which is a chiton group is found around 8,43% and the remaining species found are bivalves and cephalopoda classes.
