Scyllaea \Scyl*l[ae]"a\, n. [NL. See {Scylla}.] (Zo["o]l.)
   A genus of oceanic nudibranchiate mollusks having the small
   branched gills situated on the upper side of four fleshy
   lateral lobes, and on the median caudal crest.

   Note: In color and form these mollusks closely imitate the
         fronds of sargassum and other floathing seaweeds among
         which they live.
