Trans ‐6‐hexadecenoic acid was found in polar lipids, triglycerides, was esters and diacylglyceryl ethers of the sea anemone Metridium dianthus from Passamaquoddy Bay. The corresponding alcomaquoddy Bay. The corresponding alcohol also apparently occurs in the wax esters of this species. The long‐chain (C 20 , C 22 ) monoethylenic alcohols reported for other species of sea anemones from neighboring waters were absent and the major alcohol and glyceryl ether chain both had 16∶0 structures. The isomers of C 18 and C 20 monoethylenic fatty acids in polar lipids and triglycerides were unusual in their high proportion of the ω 7 isomer. These two lipids also contained higher proportion of the polyunsaturated fatty acids than the others.
