1994年8月至12月，在加拿大温哥华岛西海岸的巴克利海峡，记录了波利鱼、波卡迪亚和波卡迪亚的10种生境类型和取食活动。从软体动物贝壳、珊瑚藻类和藤壶等石灰性底质中分离到4种多角藻(P.Giardi、P.convexa、P.pygiial、P.limicola)和1种博卡迪亚(B.berkeleyorum)。在包括贝壳缝隙和砂岩中的泥浆沉积物中发现了两种Polydora(P.Social alis，P.Ligni)，一种Boccarella(B.Hamata)和两种Boccardia(B.prooscidea，B.Columbiana)。巴克利海湾有无聊和非无聊两种栖息地类型，没有一种同时使用这两种栖息地。用软X射线分析研究了三种钻探树种的洞穴形态特征。洞穴的结构被发现是物种特有的。软X射线在识别钻探物种和确定虫害程度方面都是有用的，而不会破坏贝壳。
Habitat types and boring activity of 10 species of Polydora, Boccardiella and Boccardia from Barkley Sound (west coast of Vancouver Island, Canada) were documented from August to December 1994. Four species of Polydora (P. giardi, P. convexa, P. pygidialis, P. limicola) and one of Boccardia (B. berkeleyorum) were obtained from calcareous substrata: mollusc shells, coralline alga, and barnacles. Two species of Polydora (P. socialis, P. ligni), one species of Boccardiella (B. hamata) and two species of Boccardia (B. proboscidea, B. columbiana) occurred in mud deposits, including mud from crevices in shells and sandstone rocks. It is suggested that there are boring and non-boring types as none of the species used both habitat types in Barkley Sound. Morphological characteristics of burrows made by three boring species were also investigated using soft x-ray analysis. The structure of the burrows was found to be species specific. Soft x-ray was useful in both identifing the boring species and determining the degree of infestation without breaking the shells.
