Koodoo \Koo"doo\, n. (Zo["o]l.)
   A large South African antelope ({Strepsiceros kudu}). The
   males have graceful spiral horns, sometimes four feet long.
   The general color is reddish or grayish brown, with eight or
   nine white bands on each side, and a pale dorsal stripe. The
   old males become dark bluish gray, due to the skin showing
   through the hair. The females are hornless. Called also
   {nellut}. [Written also {kudu}.]
