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).

简单描述
型态特徵 | 形态测量图
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).
身体矮胖的。 在嘴之前的吻长度大约 1.2 倍于鼻孔之间的距离。 长的臀鳍, 后顶端几乎延伸到下尾部叶的起源。 较大的超过对胸鳍起点的吻尖的距离胸鳍与腹鳍的起源之间的距离; 但是比较短的相较于以从吻尖到胸鳍基底的末端。 类似 A. japonicus 但是不同之处为有眼窝之间的距离大约吻部的长度在嘴之前; 鼻孔的长度大约 1/2 鼻孔之间的距离; 上下唇大约长度相等.(参考文献 41248)
Oviparous (Ref. 50449).
卵生的.(参考文献 50449)
