Several partially characterized inhibitors have been described from the marine bacterium Pseudoalteromonas tunicata, isolated from the tunicate Ciona intestinalis. This bacterium produces a diversity of metabolites, each of which specifically inhibits the settlement of invertebrate larvae...

Classification schemes have been devised that take into account the lability of tunicate blood cells (137,138). In one scheme (138) four main categories of tunicate blood cell are recognized stem cells, amoebocytes, vacuolated cells, and pigment cells (Fig. 4). Main categories are further subdivided in Ciona intestinalis, for example, hyaline amoebocytes are numerous and comprise 30% of the total blood cell population (139).
