Look Terrae, I found that site and I read it before I posted it for you to read. It clearly (note I wrote CLEARLY) that the sponges feed through those pores. The second site I gave you said that in the first sentence. I don't know how it could be stated any clearer. You must understand that we are here to try and HELP but we don't actually DO the homework. If we provide a site for you to read, its your responsibility to read the material, digest it, and write your paper/homework/paragraph or what have you yourself. You will never learn if you insist on others doing your work for you and that's what you seem to be doing.
