简单描述
检索表 | 型态特徵 | 形态测量图
背的软条 (总数) : 4 - 7; 臀鳍软条: 4; 脊椎骨: 18 - 20. Tubercles without the radiating rows of spinules as seen in D. atlanticus (forming a shagreen). Spines of tubercles extremely long and stout , especially along sides of tail. Tubercles cover the surface of disk. Principal tubercles of ventral surface of tail very large and occupying entire ventral surface except for a few small tubercles in the median portion between anus and anal fin base. Cephalic lateral line count: subopercular usually 5 (4-5); preopercular usually 2. Firm skeleton; pliant skin, especially on ventral surface of disk. Fin without tubercles except at the extreme bases of the pectoral and caudal fins. Pectoral and pelvic fins both relatively long and slender in small individuals, shorter and broader with rays very fleshy in large ones (Ref. 40826).
Body shape (shape guide): short and / or deep; Cross section: flattened.
小瘤没有放射排列的小刺如在 D. atlanticus 中见到的.(形成一个鲨鱼皮) 小瘤的棘非常长而矮胖的 , 尤其沿着尾部的侧边。 小瘤覆盖圆盘的表面。 尾部腹面的主要小瘤非常大的而且占领整个的腹面在肛门与臀鳍基底之间的中央部分中除了一些小的小瘤。 头部的侧线计数: 子鳃盖通常 5;(4-5) 前鳃盖骨通常 2. 结实的骨骼; 柔软皮肤, 尤其在体盘腹面上。 没有小瘤的鳍除了在胸鳍与尾鳍鳍的极端基底之外。 胸鳍与腹鳍两者都相当长且细的在小的个体中, 更短与更宽具有鳍条非常肉质的较大时一些.(参考文献 40826)
