Sponges were photographed in-situ and parts of them were collected for identification. The samples were either fixed in formalin and then transferred to alcohol, or directly preserved in alcohol. Then each sample was identified to genus or species using traits observable from hand-sectioned thin slides. A total of 65 species, belonging to 32 families were found in this preliminary investigation. Each sample was divided into two parts, one set is deposited in NMNS, Leiden, the Netherland, the other set is kept in NSYSU and will be deposited in National Museum of Natural Science, Taiwan.
