Abstract: Alcoholic and ether extracts of obligate herbivores, omnivores, and
detritus feeders common on Caulerpa or in its communities were found, via
comparative, and sometimes quantitative, thin-layer chromatography, to contain
varying amounts of caulerpicin, caulerpin, palmitic acid, and ß-sitosterol or to lack
them. Cerithium and soft corals, which may be either omnivores or carnivores, on
occasion contain caulerpicin. The crustacean detritus feeders did not seem to
preserve either caulerpicin or caulerpin. It seems well demonstrated that caulerpicin
and caulerpin, which, as produced by Caulerpa, are physiologically active and toxic
to rats and mice, respectively, are transferred along the food chains and concentrated
in the process at least in some herbivores.
