Ovula ovum

Some nudibranchs have adapted to feed on soft corals,270 273 ascidians,274 bryozoans,275 or on other molluscs rather than sponges. The mollusc Ovula ovum was reported to sequester the toxic sarcophytoxide (Structure 2.151) from Sarcophyton sp. and transform it into the less toxic terpene (Structure 2.152),276 but the deoxy metabolite was subsequently found in the soft coral.277...
