Spongiae \Spon"gi*[ae]\, n. pl. [See {Sponge}.] (Zo["o]l.)
   The grand division of the animal kingdom which includes the
   sponges; -- called also {Spongida}, {Spongiaria},
   {Spongiozoa}, and {Porifera}.

   Note: In the Spongi[ae], the soft sarcode of the body is
         usually supported by a skeleton consisting of horny
         fibers, or of silleceous or calcareous spicules. The
         common sponges contain larger and smaller cavities and
         canals, and numerous small ampull[ae] which which are
         lined with ciliated cells capable of taking in solid
         food. The outer surface usually has minute pores
         through which water enters, and large openings for its
         exit. Sponges produce eggs and spermatozoa, and the egg
         when fertilized undergoes segmentation to form a
         ciliated embryo.

Spongida \Spon"gi*da\, n. pl. [NL.]
   Spongi[ae].
