Porifera
n 1: coextensive with the subkingdom Parazoa: sponges [synonym:
{Porifera}, {phylum Porifera}]

Spongiae \Spon"gi*ae\ (sp[o^]n"j[i^]*[=e]), n. pl. [See
{Sponge}.] (Zool.)
The grand division of the animal kingdom which includes the
sponges; -- called also {Spongida}, {Spongiaria},
{Spongiozoa}, and {Porifera}.
[1913 Webster]

Note: In the Spongiae, the soft sarcode of the body is
usually supported by a skeleton consisting of horny
fibers, or of siliceous or calcareous spicules. The
common sponges contain larger and smaller cavities and
canals, and numerous small ampullae 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.
[1913 Webster]


Porifera \Po*rif"e*ra\, n. pl. [NL., fr. L. porus pore ferre
to bear.] (Zool.)
A grand division of the Invertebrata, including the sponges;
-- called also {Spongi[ae]}, {Spongida}, and {Spongiozoa}.
The principal divisions are Calcispongi[ae], Keratosa or
Fibrospongi[ae], and Silicea.
[1913 Webster]
