The lipids of the cystacanth of the acanthocephalan Polymorphus minutus have been analyzed. Wax esters constituted nearly 90% of the total cystacanth lipids. The wax ester fraction contained approximately 10% steroid ester; the rest was long chain alcohols C 12 to C 20 , largely saturated, esterified with fatty acids C 12 to C 22 , mostly unsaturated, with C 18 predominating. Corresponding quantities of wax esters were not found in the adult parasite. Cholesterol was identified as the only steroid present in the cystacanth.
