The lipid compositions of the livers of two species of gonatid squids, Berryteuthis magister and Gonatopsis makko, caught in the Japan Sea, were investigated.The livers yielded 22.4% lipids for B. magister and 28.0% for G. makko, each of which contained an unusually high percentage of diacyl glyceryl ethers (49.1% and 69.5%, respectively) and small amounts of steryl esters (24.0% and 16.0%), triglycerides (7.1% and 0.9%) and phospholipids (8.6% and 3.5%).In the two species, the component glyceryl ethers were reasonably similar in composition, consisting mainly of saturates (64.6-70.1%) and monoenes (27.7-33.0%) of 14-22 carbon atoms for the alkyl moiety. The principal components were as follows: 16:0 (58.3-58.5%), 18:1 (23.2-27.7%), 18:0 (4.0-7.6%), and 20:1 (3.4-4.1%). In both species, the fatty acid compositions of diacyl glyceryl ethers consisted predominantly of monoenes with 18:1 acid (28.2-46.6%) as the main component.For B. magister, few differences were found in the percentages of the component fatty acids among the lipid classes of diacyl glyceryl ethers, steryl esters, triglycerides and phospholipids; and for G. makko few differences were found among diacyl glyceryl ethers, steryl esters and phospholipids.
