What is a Leuconoid?
Leuconoid sponges are the most complex in design in that not all the chambers are flagellated. Water flowing in through incurrent canals is selectively pumped through those chambers which are, and expelled via one of a series of oscula. Leuconoid sponges are the best adapted to increase sponge size.
What do you mean by Demospongiae?
Definition of Demospongiae : a large class of Porifera comprising the majority of living sponges and being characterized by complex structure with a skeleton of tetraxial or simple siliceous spicules or of fibers of spongin or of both.
What are the two groups of Demospongiae?
Demosponges other than the Homoscleromorpha are split into two major groups, the Tetractinomorpha and the Ceractinomorpha. These two groups share characters that indicate common descent such as a distinctive larval type and the presence of spongin.

What are Prosopyles and Apopyles?
Water enters the sponge through these pores and moves into the incurrent canal. Water leaves this area to enter the. radial canal (area of choanocytes) via the prosopyle – (a porocyte cell) Water leaves the area of choanocytes via a much larger pore, made by many cells = the apopyle.
