The China rockfish has a distinctive appearance, with a dark blue or black body crossed by a patchy but obvious yellow stripe that extends from around the third dorsal spine down and then along the lateral line. The body of the China Rockfish may be covered with small whitish or yellowish spots. Maximum reported size is 45 cm (18 inches). Adults are solitary and territorial, preferring rocky outcrops with boulder fields and crevices.
