The marine bryozoan,Watersipora subovoided,is a common bryozoan in Japan.Bryozoa are generally colonial and sessile animals.Colonial and sessile animals often show colony specificity (=allogeneic recognition between colonies),as colonial ascidians.Colonies of W.subovoided also show colony specificity(Ishii and Saito,1995).In colony specificity of colonial ascidians,blood cells and humoral factors play key roles.Then,we firstly exmined the coelomocytes(=blood cells in ascidiens) of W.subovoidea.There are 4 distinct cell types in this bryozoan;granular cells,granular filopodial cells,vacuolated cells and phagocytes.Among them,only phagocytes had ability of phagocytosis.We also examined the morphology of W.subovoidea histologically.
