It is also known that several halogenated metabolites of the dictyoceratid sponge Dysidea herbacea are produced by the cyanobaderium Oscillatoria spongeliae and that filamentous cyanobacteria of the genus Beggiatoa are the source of many metabolites of lithistid sponges, which are all repellents or toxic to fish (Unson and Faulkner, 1993 Fatdkner et al., 1993 Faulkner, Unson, and Bewley, 1994 Unson, Holland, and Faulkner, 1994 Bewley and Fatdkner, 1998 Schmidt, Bewley, and Faulkner, 1998 D Auria, Zampella, and Zollo, 2002 Ridley et al., 2005).
