Gonadal and foot tissues of the green abalone, Haliotis fulgens , raised on artificial diets, were analyzed for lipids using thin‐layer chromatography/flame‐ionization detection and gas chromatography‐mass spectrometry (GC‐MS). Diacylglyceryl ether (DAGE) was 0.7% of total lipids in the gonad. The major alkyl constituents of the glyceryl ether diols in the gonad (as % of total diols) were 16∶0 (38%) and 18∶1 (36%). While levels of DAGE in the abalone foot were below flameionization detection limits, glyceryl ether diols from them were detected using the more sensitive GC‐MS procedure. The major diol components in the foot were 18∶0 (39%) and 18∶1 (32%). To our knowledge, this is the first report of DAGE in abalone tissues. Although the precise role of DAGE in abalone remains to be determined, a possible structural role may exist.
