Remora \Rem"o*ra\ (r?m"?*r?), n. [L.: cf. F. r['e]mora.]
   1. Delay; obstacle; hindrance. [Obs.] --Milton.

   2. (Zo["o]l.) Any one of several species of fishes belonging
      to {Echeneis}, {Remora}, and allied genera. Called also
      {sucking fish}.

   Note: The anterior dorsal fin is converted into a large
         sucking disk, having two transverse rows of lamell[ae],
         situated on the top of the head. They adhere firmly to
         sharks and other large fishes and to vessels by this
         curious sucker, letting go at will. The pegador, or
         remora of sharks ({Echeneis naucrates}), and the
         swordfish remora ({Remora brachyptera}), are common
         American species.

   3. (Surg.) An instrument formerly in use, intended to retain
      parts in their places. --Dunglison.
