    An olefinic hydrocarbon (all-cis-3,6,9,12,15,18-heneicosahexaene, ldquoHEHrdquo)_was islated from marine planktonic plants and animals. Its structure was established by ultraviolet, infrared and mass spectrometry in combination with chemical techniques. The olefin occurs in many species of marine planktonic algae and is probably derived from the corresponding docosahexaenoic acid. Rhincalanus nasutus accumulates HEH nonselectively from its algal food together with the triglyceride lipids. Other, related copepods contain little or no HEH even when grown in cultures of algae that provide R. nasutus with that olefin. The presence of HEH in marine vertebrates suggests that, within the animal lipids, hydrocarbons are remarkably stable. This work has practical implications for studies of the marine food web and of marine pollution with persistent chemicals.
