The content and composition of alkyl glyceryl ethers of liver lipids of the gonatid squid Berryteuthis magister in the northwestern Pacific were investigated.<br> Weight of the livers of thirty specimens of this species accounted for 9.6±3.7% of total body weight; 35.2±15.6% of the liver was lipids. The liver lipids contained significant amounts of unsaponifiables (23.8±4.4%), consisting of 76.5±16.2% alkyl glyceryl ethers and 20.2±15.4% sterols. Alkyl glyceryl ethers originated from the constituent diacyl glyceryl ethers (46.5±17.8%) of the liver lipids. The relationship between the amounts (Y, g) of alkyl glyceryl ethers of liver and liver weight (X, g) was expressed by the following equation: Y=0.002+0.83X (r=0.966, P<0.05).<br> The component alkyl glyceryl ethers were found to consist mostly of saturates (77.8±3.6%) and monoenes (20.0±3.2%) of 14-20 carbon numbers for the alkyl moiety. The principal com-ponents found were: chimyl (16:0, 71.1±4.0%), selachyl (18: 1, 17.0±2.5%), and batyl (18:0, 3.5±1.5%) alcohols. It was concluded that the liver of the gonatid squid species was a good source of alkyl glyceryl ethers having chimyl alcohol as its predominant component. In addition, the component fatty acids of the liver lipids were discussed.
