The changes in lipid-class profiles (polar lipids, total neutral lipids, free sterols, steryl esters, triacylglycerols, neutral ether lipids and free fatty acids) which are manifest during the annual reproductive cycle of the seastar A. rubens for both the storage organs (pyloric ceca) and utilizing organs (ovaries) are presented. The ovaries appear to accumulate all individual lipid components proportional to progression of vitellogenesis. Pyloric ceca show variable lipid-class levels, probably due to more complex processes in these organs, operating simultaneously: digestion of food, accumulation of storage lipids, mobilization of stored lipids and their release. The results are discussed in terms of current knowledge on the role of lipids in echinoderm reproduction.
