vorous and carnivorous fishes can cause ciguatera poisoning, the latter
fishes are the more toxic, and in some areas are the only fishes sufficiently toxic to cause poisoning in man. This would indicah that the
more predaceous species feed upon the toxic herbivorous species, and

that they in some manner accumulate the toxin without deleterious
effects. The herbivorous forms may feed on a toxic alga, fungus or
protistan, but the present evidence favors the blue-green algae
(Cyanophyta) as the most probable common source for the oiguatera
toxin. Randall (1968) has discussed the possible role of these algae
