The surface lipids of the crustacean Ligia oceanica have been isolated, and the hydrocarbons separated into six major fractions. The n-alkanes, with a maximum chain length at C33 and a minimum at C14, are the largest fraction (3·85%); the others are 2,6,10,14-tetramethylpentadecane (pristane)(0·82%), heptadec-8-ene (0·55%), heptadeca-8,13-diene (0·45%), two unknown hydrocarbons (0·65%), and cholestadiene (0·3%), the last identified for the first time in marine lipids.
