   (Zo["o]l.)
   Same as {Pycnogonida}.

Pycnogonida \Pyc`no*gon"i*da\, n. pl. [NL., fr. Gr. ? thick
   crowded + ? knee.] (Zo["o]l.)
   A class of marine arthropods in which the body is small and
   thin, and the eight legs usually very long; -- called also
   {Pantopoda}.

   Note: The abdomen is rudimentary, and the triangular mouth is
         at the end of a tubular proboscis. Many of them live at
         great depths in the sea, and the largest of them
         measure two feet across the extended legs.
