The pores in a sponge are used to filter the water, and while doing that they collect food to eat
Pore cell
A sponge contains a lot of pore space that are filled with air or water at any given time. Squeezing a sponge temporarily collapses these pore spaces and forces the air or water out.
An apopyle is a pore through which water passes out of a radial canal or flagellated chamber of a sponge.
ostium
Small pores of sponges are called ostia through which water enters while a large pore through which water exits is called osculum .
