Nostrils are longer, crown is flat transversely or even slightly convex, tubercles in median row are larger, thorn like, numerous. Origin of first dorsal is posterior to the tips of pelvic fins, equal to the base of first dorsal. Upper surface uniform olive gray or chocolate brown, without pale or dark markings. Snout with an oval sooty patch (Ref. 6902).
Body shape (shape guide): elongated.
鼻孔比较长, 冠横着是平坦的或者平坦的些微中凸, 在中央的列的小瘤比较大, 刺例如很多的。 第一背鳍的起源是在腹鳍顶端后面, 等于第一背鳍的基底。 上表皮全橄榄色或褐色, 没有灰白的或深色斑纹。 吻部有一个椭圆形的小黑斑。 (参考文献 6902)

Found from the coast line to the continental edge. Females mature at ca. 90 cm TL (Ref. 114953). Feeds on crustaceans, cephalopods, polychaetes and small fishes. Ovoviviparous (Ref. 50449). Produces litters of 4-12 pups (Ref. 114953).
