Check online livestock vendors - enter the required item name in the Google (google.com) and the word price - you will see who has them now for sale.

I would be extremely surprised if any vendor had even the slightest clue how to identify their sponges to genus. You could go by the names they give, but chances of them being right are very small. Even if you did find the right sponge, buying enough to feed your slug would be prohibitively expensive.

If you've already got the slug my suggestion would be to try feeding it angelfish food that contains sponge. If you don't already have the slug I would say skip it.

I did a quick net check and couldn't find any source for commercial purchase of these animals. LFS sell "yellow sponge", "orange tree sponge", "white puffball sponge", etc, with no attempt to id them. Mike has the best advice - try the angelfish food if you have nudis. Don't buy them no matter how pretty they are.
