Morphology | Morphometrics
spines: 0. The head large; the eyes also large; snout tipped with a scute of moderate size, not especially set off by its size or spines from the adjacent scales. Head ridges moderately supported by coarse scales. Most body scales with small fine, reclined spinules arranged in an irregular quincunx to sub parallel pattern. Overall color is medium brown to swarthy, darker on the abdomen and chest; the underside of the head with small melanophores; the fins are dusky, their inner bases black.
Frequently occurs below 350 m depth in winter. Feeds on benthic crustaceans and polychaetes (Ref. 54164).
