The phospholipid fatty acids from the sponge Euryspongia rosea were studied revealing the presence of the new 6,11‐eicosadienoic (20∶2) acid and the rare 6,11‐octadecadienoic acid (18∶2). The isolation of these 6,11‐dienoic acids reveals the presence of new biosynthetic possibilities in sponges and suggests the presence of an active Δ6 desaturase in E. rosea . Other acids isolated from E. rosea include 12‐eicosenoic (20∶1) and 17‐tetracosenoic acid (24∶1). The major phospholipids encountered in the sponge were phosphatidylethanolamine (PE), phosphatidylserine (PS), and phosphatidylcholine (PC).
