Etymology: Poroclinus: Greek, poros = porous + Greek, klinein, kline = sloping and bed, due to the four apophyses of sphenoid bone (Ref. 45335); rothrocki: Named for Dr. J.T. Rothrock, botanist at the Universitiy of Pennsylvania (Ref. 6885). More on author: Bean.
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 46 - 128 m (Ref. 2850). Temperate

(total): 57 - 67;
soft rays: 40 - 44. Caudal long, narrow, bluntly pointed; pectorals broad and rounded (Ref. 6885). Light brown on dorsal surfaces, lighter ventrally; about 10 to 12 white vertical bars edged with brown in a series on upper part of body, spreading or dividing to become confluent with pale ventral coloring; small brown smudges at bases of membranes between spines of posterior part of dorsal fin (Ref. 6885).
