The composition of octopus ( Octopus vulgaris ) phospholipids was determined by analysis of hydrolytic breakdown products and by chromatography on silicic acid. The most remarkable feature of octopus phospholipids was the high content (13%) of ceramide aminoethylphosphonic acid. In addition the phospholipids contained phosphatidylcholine (42%), phosphatidylethanolamine (30%), phosphatidylserine (5%), phosphatidylinositol (4%) and sphingomyelin (3%). The fatty acid distribution of the phospholipids and the non‐phosphorylated lipids was determined by gas chromatography. The major saturated fatty acids in the phospholipids and non‐phosphorylated lipids were 16:0 (24 and 23%, respectively) and 18:0 (10 and 15%, respectively). The major highly unsaturated fatty acids in phospholipids and non‐phosphorylated lipids were 20:5 (18 and 7%, respectively) and 22:6 (23 and 9% respectively).
