The polyp of Chrysaora quinquecirrha (sea nettle) has two forms of nematocytes on the oral arms and upper stalk. A nematocyte with an unencapsulated thread and another containing an encysted heteroneme were observed. One or both of these structures were capable of producing a clinical sting in humans. The relationship of these structures with similar nematocytes present in sea nettle medusae is discussed.
