• The lipid content and class composition of the digestive gland, mantle and stomach fluid of the gonatid squid Berryteuthis anonychus collected in the North Pacific are described. The digestive glands contained large amounts of lipids (20.0-35.6%), which comprised mainly triacylglycerols (TAG: 57.1-77.3%) and diacyl glyceryl ethers (DAGE: 12.9-14.6%). The mantles contained the least amounts of lipids (1.3-1.4%), which comprised phospholipids (76.2-79.4%), TAG (0.1%) and trace amounts of DAGE. The stomach fluids contained low amounts of lipids (4.5%), which comprised wax esters (75.2%), TAG (4.7%) and DAGE (0.9%). The main components of the alkyl chains in DAGE from the digestive glands were 16:0 (50.7-57.3%), 20:1n-11 (6.2-8.0%), 16:1n-7 (3.7-7.1%) and 18:0 (2.8-7.9%) alcohols. Component fatty alcohols originating in wax esters from the stomach fluids were rich in monoenes (90.9%), including 22:1n-11 (45.3%) and 20:1n-11 (15.3%) alcohols. The fatty acid compositions of DAGE and TAG in the digestive glands, of phospholipids in the mantles, and of wax esters and TAG in the stomach fluids are also discussed.
