摘　　要：The distributions of two ubiquitous fouling cheilostome bryozoans,Cryptosula pallasiana(Moll,1803)and W atersipora sp.,on a ship moored for almost six years in Qingdao Bay show diff erences with respect to illumination,C ryptosula being dominant on the side of the ship which was exposed to the sun and Watersipora dominating on the other side which was in shadow for most of the time.Competitive interactions for substrate space were nearly always won by Watersipora,which succeeded in overgrowing the edges of C ryptosula colonies regardless of the side of the ship.Reasons for the superiority of W atersipora in spatial competition with Cryptosula could include faster growth rate and the stronger feeding currents created by the larger lophophores of Watersipora.The distributions of two ubiquitous fouling cheilostome bryozoans, Cryptosula pallasiana （Moll, 1803） and Watersipora sp., on a ship moored for almost six years in Qingdao Bay show differences with respect to illumination, Cryptosula being dominant on the side of the ship which was exposed to the sun and Watersipora dominating on the other side which was in shadow for most of the time.
