Sponge (1391 words)
The structure of a sponge is simple: it is shaped like a tube, with one end stuck to a rock or other object and an open end, the osculum, open to the environment.
The spongocoel, or interior of the sponge, is composed of walls perforated with microscopic pores that allow water to flow through the spongocoel.
Porocytes are tubular cells that make up the pores into the sponge body through the mesohyl.
