     The fatty acids and sterols composition of the marine tunicates C.Savignyi, C.Squamulata and the brown alga C.Tamariscifolia are reported from the Moroccan Atlantic Ocean. From all the fatty acids identified the acid C16:0 is present at high concentration in the two tunicates. And also the tunicates contain various C27, C28 and C29 sterols with cholesterol as the main sterol. In the brown alga C. tamariscifolia, the fatty acid C14:0 is predominant and Fucosterol is the main sterol present in this alga.
