I've seen this same sponge down in Port Orford, southern Oregon, and Newport, central Oregon. I also ID'd it as Xestospongia hispida, but until now could not find a photo in guides or online that looked so similar to what I saw as this one does. I sought feedback from professional naturalists, who told me that, as best they can determine from the photos, it was indeed Xestospongia.

Thanks for the input Doug. I have been told that many sponges cannot be id'd without samples. Appreciate confirmation.
