背棘 (总数) : 0; 臀棘: 0. A small, compressed dogfish shark with a blunt snout, ear-shaped pectoral fins, and gill slits increasing greatly in width from front to back; cloaca area with a large luminous gland not found in other sharks (Ref. 5578). Brown with black underparts (Ref. 6577); fin margins conspicuously white (Ref. 5578).
一种小的, 扁长形的狗鲨具有一个钝的吻，耳朵-形状的胸鳍 , 与被从前面到背面宽度增加很多的鳃缝; 泄殖腔区域具有一个大的发光腺不出现在其他的鲨鱼.(参考文献 5578) 褐色且有黑色的下部;(参考文献 6577) 鳍边缘显着白色.(参考文献 5578)
Probably oceanic but also near the upper slope (Ref. 5578). The holotype was caught in a bottom trawl between 457 and 640 m, a second specimen was collected in the open ocean near the surface at less than 25 m (Ref. 247, 5578). Food unknown but the powerful jaws and sharp teeth suggest that this species can take relatively large prey (Ref. 247). Probably ovoviviparous with few young (Ref. 247).
可能大洋性也在上层斜坡的附近.(参考文献 5578) holotype 于在 457 与 640 公尺之间的一个底拖网捕获, 一件第二件标本在开放性海域接近水表面在少于 25 公尺被收集。 (参考文献 247,5578) 食性未知但是有力的颚与锐利的齿显示出，这种能吃比它大的猎物.(参考文献 247) 可能卵胎生有些幼鱼.(参考文献 247)
