簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 4 - 7; 臀鰭軟條: 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.
小瘤沒有放射排列的小刺如在 D. atlanticus 中見到的.(形成一個鯊魚皮) 小瘤的棘非常長而矮胖的 , 尤其沿著尾部的側邊。 小瘤覆蓋圓盤的表面。 尾部腹面的主要小瘤非常大的而且佔領整個的腹面在肛門與臀鰭基底之間的中央部分中除了一些小的小瘤。 頭部的側線計數: 子鰓蓋通常 5;(4-5) 前鰓蓋骨通常 2. 結實的骨骼; 柔軟皮膚, 尤其在體盤腹面上。 沒有小瘤的鰭除了在胸鰭與尾鰭鰭的極端基底之外。 胸鰭與腹鰭兩者都相當長且細的在小的個體中, 更短與更寬具有鰭條非常肉質的較大時一些.(參考文獻 40826)
