背棘 (總數) : 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).
一種小的, 扁長形的狗鯊具有一個鈍的吻，耳朵-形狀的胸鰭 , 與被從前面到背面寬度增加很多的鰓縫; 泄殖腔區域具有一個大的發光腺不出現在其他的鯊魚.(參考文獻 5578) 褐色且有黑色的下部;(參考文獻 6577) 鰭邊緣顯著白色.(參考文獻 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).
可能大洋性也在上層斜坡的附近.(參考文獻 5578) holotype 於在 457 與 640 公尺之間的一個底拖網捕獲, 一件第二件標本在開放性海域接近水表面在少於 25 公尺被收集。 (參考文獻 247,5578) 食性未知但是有力的顎與銳利的齒顯示出，這種能吃比它大的獵物.(參考文獻 247) 可能卵胎生有些幼魚.(參考文獻 247)
