The present paper deals with thoracic cirripeds collected in the supralittoral, mediolittoral, and upper infralittoral zones of Antalya Bay (eastern Mediterranean, Turkey) between August 2009 and January 2010. A total 13477 specimens belonging to 7 species and 6 genera were found in the area. Among these, Chthamalus montagui and Lepas anatifera are new records for the Mediterranean coast of Turkey. Chthamalus stellatus is the dominant species in the supralittoral and mediolittoral zones, reaching a maximum density of 69600 ind.m-2 and a biomass of 3100 g.m-2. Perforatus perforatus was the dominant species in the infrallitoral zone, comprising 71% of the total number of individuals and 85% of the total biomass in this zone. Biometrical features of the shells of the dominant species were analysed and their length-weight relationships were estimated. In addition, a check-list of the thoracic cirripeds that have been reported from the coasts of Turkey up to date is provided.
