Nudibranch mollusc

The scope of the majority of the papers is limited to the ascertainment of the existence of de novo biosynthesis of a particular compound. In this respect it has recently been proposed that in many cases it would be possible to predict the origin of secondary metabolites in nudibranch molluscs by examining their geographical variations in a given species [10]. Those molluscs that exhibit considerable variation in their chemical constituents undoubtedly obtain these from dietary sources, while those that have the same substances wherever they are collected are most likely capable of de novo biosynthesis.

Aside from this work, eicosanoid biosynthesis has been recorded in a nudibranch mollusc, Tethys fimbria [62-64]. This nudibranch produces prostaglandin 1,15-lactones, which are transferred from the mantle to egg masses just before egg fertilization and release [64], again suggesting the compounds are major players in the biology of reproduction.
