Abstract

In the present study, a total of 11 bioeroding sponge species belonging to 4 families were found on rocky substrata in Ildırı Bay (eastern Mediterranean), five of which (Dotona pulchellamediterraneaVolzia albicansDelectona madreporicaSiphonodictyon infestum and Thoosa mollis) are new records for the eastern Mediterranean fauna. The most abundant and frequent species in the area were Chondrosia reniformisSpirastrella cuntatrix and Cliona celata. The morphological and distributional features of the species that are new to the Turkish marine fauna are presented. In addition, a checklist of the bioeroding sponge species reported from the Mediterranean coasts to date is provided.
