Etymology: Apristurus: a-, Latin privative, i.e., without; pristis, from pristes (Gr.), sawyer (but here meaning saw); oura (Gr.), tail, referring to absence of saw-toothed crest of enlarged dermal denticles along upper edge of caudal fin as found in the closely related Pristiurus (=Galeus) (See ETYFish); pinguis: Latin for fat, described as having a “stout” body (See ETYFish).

簡短描述
檢索表 | 型態特徵 | 形態測量圖
Body stout. Snout length in front of mouth about 1.2 times the distance between nostrils. Long anal fin, rear tip nearly reaching origin of lower caudal lobe. Greater distance between origins of pectoral and pelvic than the distance of tip of snout to origin of pectoral fin; but shorter compared to that from tip of snout to end of pectoral base. Similar to A. japonicus but differs in having distance between orbits about the length of snout in front of mouth; length of nostril about 1/2 distance between nostrils; the upper and lower labials about equal in length (Ref. 41248).
Body shape (shape guide): elongated.
身體矮胖的。 在嘴之前的吻長度大約 1.2 倍於鼻孔之間的距離。 長的臀鰭, 後頂端幾乎延伸到下尾部葉的起源。 較大的超過對胸鰭起點的吻尖的距離胸鰭與腹鰭的起源之間的距離; 但是比較短的相較於以從吻尖到胸鰭基底的末端。 類似 A. japonicus 但是不同之處為有眼窩之間的距離大約吻部的長度在嘴之前; 鼻孔的長度大約 1/2 鼻孔之間的距離; 上下唇大約長度相等.(參考文獻 41248)
