With a short, stout body and a large head with elongate snout, the resemblance of a grunt sculpin to a pig is only enhanced by
the way it uses its large pectoral fins to scoot around on the seabed. The lower rays of the pectoral fin are elongate and have almost no webbing. The body is covered with small, bristly spines. All of the fin rays are unbranched and the tail bones are fused, as in poachers (Agonidae). These fish grow to 3.3 in (8.3 cm).
