Head somewhat depressed, its length about 6cm. The snout is blunt in profile and It is moderate in size, the upper jaw extending to mid-pupil.
The species is very abundant in tide pools around rocky the rocky shores of Race Rocks. Tide pool sculpins show a definite tendency to return to their home pool if moved. These are very abundant in the tidepools on the north east corner of Great Race Rock. A piece of edible tissue dropped into a pool usually causes a feeding frenzy.
