The body of the vermilion rockfish is moderately deep and compressed. The upper profile of the head is some what curved; the mouth is large, with the lower jaw slightly projecting. The color is bright red on the body and fins; many with black and gray mottling on back and sides. On fish shorter than 12 inches, the mottling is much more apparent and the fins are often edged with black. The yelloweye and canary rockfishes are similar in appearance to the vermilion, but the bottom of the yelloweye and canary's lower jaws are scaleless and feels smooth to the touch. The vermilion rockfish has scales on the bottom of the lower jaw which make it rough to the touch.
