Abstract: The phospholipid fatty acid contents of six Haplosclerida sponges collected along Qatari ;ts, Arabian Gulf, were identified by coupling GC-MS experiments. More than hundred of rated and unsaturated fatty acids have been identified. Strong variations were observed for both rated and unsaturated fatty acids within the three studied genera: Callyspongia, Gelliodes, and tates. A new dienoic fatty acid: 14-Me-5,9-17:2 and several rare or uncommon fatty acids were tified from GC/MS coupling experiments. Striking differences between both Gelliodes species e observed for fatty acids belonging to the n-7 family with total content ranging from 0 to 18%.
