簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 11; 背的軟條 (總數): 16-17; 臀棘 3; 臀鰭軟條: 8. Preopercle angle with 2 - 4 distinctly enlarged serrae; upper edge of the operculum straight or nearly so; nostrils small, subequal; maxilla extends to below rear half of the eye. Color is pale brownish gray with yellow or golden brown spots on the head, nape and chest. A row of dark yellowish brown spots along the margin of the soft dorsal and anal fins and the rear edge of the caudal fin. Pelvic fins with yellowish brown and whitish streaks and a few yellowish brown spots distally. Further characterized by body depth contained 2.7-3.4 times in SL; head length 2.4-2.7 times in SL; flat to convex interorbital area; 2-4 distinctly enlarged serrae at preoopercle angle; upper edge of operculum nearly straight or straight; small anterior and posterior nostril, subequal; maxilla extends to below rear half of eye; 2 rows of teeth on midlateral part of lower jaw (Ref. 89707).
前鰓蓋骨角有兩個 - 4 明顯地增大了鋸齒; 鰓蓋直線的上緣或很接近; 鼻孔小的, 幾乎相等的; 顎骨在後面一半的眼之下延伸到。 色彩是淡褐色的在頭部,後頸與胸上灰色的有黃色或金褐色斑點。 一排深色的土黃色斑點沿著軟背鰭與臀鰭與尾鰭的後緣的邊緣。 末梢部地的腹鰭有土黃色與微白色的條紋與一些土黃色斑點。

生物學特性     字彙 (例如 epibenthic)

Nothing has been published on the biology of this rare species. The apparent rarity of this species is probably a result of its deep-water habitat and the fact that it was only recently described as a new species.

在這稀有的種的生物學特性上尚未有任何文獻報告。 可能是一個它的深水域棲息地的結果與它最近只有被描述為一個新種的事實的這種的明顯稀有性。
