We compared the occurrence of every single species with water temperature measured when the samples were taken. A slight tendency in the relative occurrence connected to the temperature was located, i.e. 
O. cf. ovata was far more abundant in warmer water, whereas Ostreopsis sp. more frequently occurred in cooler water (Fig. ).Mouse bioassayMice injected with all the methanolic fractions of Ostreopsis clones displayed symptoms typical of palytoxin activity.

qualities of clones fitted effectively into the species description of O. ovata as follows; live cells swam having a geotropic orientation, remainingattached to a bottom in the culture nicely; cells are anterioposteriorly compressed and have golden plastid, and normally have large vacuole(s) at the ventral finish (Figs. A, B); the plate pattern was Po,,,,, p (Figs. C ); thecal surface is smooth, ormented with minute, evenly distributed pores (Figs. F ).
