The lipid class compositions of the livers of two different size groups and of the mantles of gonatid squid Gonatopsis borealis from the northwest Pacific Ocean were investigated. In this species, the liver had a remarkably high level of lipids (26.5%), which were characterized by diacyl glyceryl ethers (16.3%) and triglycerides (33.0%). The liver lipids of the small-size squids (mantle length: 13.4 cm) contained relatively higher levels of diacyl glyceryl ethers (27.0%) than those (10.3%) of the large ones (22.5 cm). On the contrary, the mantle contained only trace amounts of these lipids but were high in phospholipids (84.0%). In the livers of the two different size groups and the mantle of this species, glyceryl ethers originating from diacyl glyceryl ethers were very similar in composition; the most abundant component was chimyl alcohol (38.6 to 45.9% and 66.2%, respectively). Among the tissues examined, differences were found in the percentage of component fatty acids of the total lipids.
