Phospholipid fatty acid composition was studied in sponge from Qatar including eight Demospongia and one Calcarea. More than 60 fatty acids were identified in each species as methyl esters and N-acyl pyrrolidides by gas chromatography-mass spectrometry. Twenty-two typical Delta-5,9 fatty acids were identified (C16 to C28), including two brominated acids. An unusual level (68%) of Delta-5,9 fatty acids was found in Dysidea sp. A new fatty acid was identified, namely 14-methyl-5,9-heptadecadienoic acid. Six unusual C18 and C20 acids were identified with the Delta-5,9, Delta-6,11 and Delta-7,13 unsaturations.
