Comparisons of the total fatty acids from some North Atlantic (Newfoundland) spring copepods (mostly Temora longicornis ) and from associated sea water have been made. The animal fatty acids were similar in composition to published data for other copepods and this suggests a basic differentiation among planktonic crustacea by which species and genus fatty acid compositions may be compared. The fatty acids recovered from sea water unexpectedly showed a high proportion (∼9%) of arachidic acid, which is normally a very minor component in marine lipids of either plant or animal origin. The evidence bearing on widespread occurrence of this acid in sea water and sediments is reviewed.
