In the field of zoology, a spadix (/ˈspeɪdɪks/ SPAY-diks; plural spadices /ˈspeɪdɪsiːz/ SPAY-dih-seez, /speɪˈdaɪsiːz/ spay-DY-seez) is a secondary sexual organ found in some cephalopods and hydrozoans. In the genus Nautilus, the spadix is a composite erectile organ in the male located in the oral region which is composed of four highly modified tentacles and which is paired with a somewhat smaller antispadix that is also composed of four tentacles. The spadix is normally a concealed organ but quickly becomes distended upon the animal's death. The exact function of the spadix and antispadix in Nautilus is not yet known.
