This is a sponge collected from underneath the docs in Newport, Oregon. In this video the sponge was observed through a dissecting microscope. While it was being observed under the microscope, a nudibranch was found slowly moving on the sponge’s surface. When the nudibranch moves, the sponge responds by closing its ostium (pores).
