简单描述 型态特徵 | 形态测量图

背的软条 (总数): 6; 臀鳍软条: 4; 脊椎骨: 18 - 19. Body relatively firm, skin tough. Large tubercles with rows of bosslike spinules radiating out from the central spine along the ridges between facets (as seen in D. atlanticus like shagreen). Jaw relatively long compared to D. atlanticus, 14.6% of SL. Cephalic lateral-line counts: subopercular 6, preopercular, 2. Tail lateral-line counts 12-15. Fin-rays with fine tubercles on dorsal and caudal fins and dorsal side of pectoral fins, running out for about half the length of the fin ray. Ventral surface of pelvic fin rays have tubercles near fin base. Paired fins relatively slender with fin membranes transparent (Ref. 40826).
身体相当结实的, 皮肤强硬的。 大瘤有放射出从中央的棘的列的 bosslike 小刺沿着在刻面之间的脊.(如在像鲨鱼皮一样的 D. atlanticus 中见到的) 颌相当长的相较于 D. atlanticus , 14.6% 的 SL。 头部的侧线计算: 子鳃盖 6 ,前鳃盖骨,2. 尾部侧线计算 12-15 。 鳍条在背鳍与尾鳍鳍与胸鳍的背面两侧上有细的小瘤,为大约一半鳍鳍条的长度跑出。 腹鳍鳍条的腹面有在鳍的基底附近的小瘤。 偶鳍相当细长且有鳍薄膜透明.(参考文献 40826)

Estimates based on models

Preferred temperature (Ref. 123201): 8.4 - 11.4, mean 9.5 °C (based on 5 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00770 - 0.05171), b=2.96 (2.73 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  3.4   ±0.6 se; based on size and trophs of closest relatives
回复力 (Ref. 120179):  中等的, 族群倍增时间最少 1.4 - 4.4年 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
