This species forms small colonies but are sometimes densely packed together to look like one big one spread out over the bottom. Undisturbed, it usually is brownish in color with a fuzzy appearance. When disturbed, the tiny brown polyps retract, leaving a mostly white bumpy lump crowded with small black holes. We have seen these being eaten by the gastropod Ovula ovum, especially juvenile individuals as in the first two photos below.
