Research Abstract |
Species of Polydora and related genera (Polychaeta, Spionidae) are collectively called polydorids and they are widely known for their boring activities into calcareous substrates such as molluscan shells. We investigated the boring species inhabiting natural and cultured mollusk shells in southwestern Australian waters, China, Korea and Japan. Polydora uncinata is reported to be one of the most dangerous species inhabiting cultured mollusks in the world today and the species was firstly extracted from the shells inhabiting Australian waters during this study. The species was also newly extracted from the shells of the cultured mollusks indicate that it is important to understand and discuss the human impact caused by fishery products transportation.
