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);  melanoasper: melanos (Gr.), black; asper (L.), rough, referring to black body color and rough skin. (See ETYFish).

简单描述 型态特徵 | 形态测量图

Diagnosis: Body uniformly black, slightly brownish in larger specimens. Dermal denticles large and giving a rough texture to the skin. Upper labial furrows longer than the lower ones. First dorsal fin only slightly smaller than the second dorsal fin, originating from above anterior third to middle of the pelvic fin base. Second dorsal fin insertion just before level of anal fin insertion. Interorbital space 1.9-3.5 times eye horizontal diameter. Abdomen between pectoral fin tip and pelvic fin origin 1.3-2.5 times pectoral fin width. Spiral valves of the intestine 19-23 (mostly 21-22). Monospondylous + precaudal diplospondylous vertebrae 36-43 + 26-32 (often 38-40 + 28-30). Dermal denticles on tongue and palate absent (Ref. 56212).
鉴别: 身体均匀黑色, 些微褐色在较大的标本中。 表皮的细齿大的而且给一个粗糙的质地到皮肤。 上面的唇沟长度超过下面的一些。 第一背鳍只些微地比第二个背鳍更小, 起源于在对腹鳍基底的中央的前三分之一上面。 就在臀鳍嵌入的水平之前的第二背鳍鳍嵌入。 倍眼水平的直径眼间隔 1.9-3.5。 倍胸鳍宽度的在胸鳍顶端与腹鳍起点 1.3-2.5 之间的腹部。 肠 19-23 的螺旋形瓣膜.(大部份 21-22) Monospondylous+ 尾前椎双体椎型的脊椎骨 36-43+26-32.(时常 38-40+28-30) 在舌與上顎上的表皮的細齒不存在。 (參考文獻 56212)

Estimates based on models

Preferred temperature (Ref. 123201): 3.5 - 9.9, mean 7.2 °C (based on 79 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00355 (0.00176 - 0.00714), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  4.0   ±0.4 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  非常低的, 最小族群倍增时间超过14 年 (Fec assumed to be <10).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100).
Nutrients (Ref. 124155):  Calcium = 8.66 [1.82, 62.13] mg/100g; Iron = 0.255 [0.057, 1.009] mg/100g; Protein = 19.6 [17.3, 21.9] %; Omega3 = 0.115 [0.035, 0.351] g/100g; Selenium = 13.7 [3.4, 53.5] μg/100g; VitaminA = 13.5 [1.6, 98.3] μg/100g; Zinc = 0.388 [0.159, 0.952] mg/100g (wet weight);
