Ctenophora \Cte*noph"o*ra\ (t?-n?f"?-r?), n. pl. [NL., from Gr.
   ???, ???, comb + ???? to carry.] (Zool.)
   A phylum of invertebrates, commonly ellipsoidal in shape,
   swimming by means of eight longitudinal rows of paddles. They
   are commonly called the comb jellies, because the separate
   paddles somewhat resemble combs. This phylum was formerly
   classified as a subdivision (class) within the
   C[oe]lenterata.
