簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 6; 臀鰭軟條: 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).
身體相當結實的, 皮膚強硬的。 大瘤有放射出從中央的棘的列的 bosslike 小刺沿著在刻面之間的脊.(如在像鯊魚皮一樣的 D. atlanticus 中見到的) 頜相當長的相較於 D. atlanticus ， 14.6% 的 SL。 頭部的側線計算: 子鰓蓋 6 ，前鰓蓋骨,2. 尾部側線計算 12-15 。 鰭條在背鰭與尾鰭鰭與胸鰭的背面兩側上有細的小瘤,為大約一半鰭鰭條的長度跑出。 腹鰭鰭條的腹面有在鰭的基底附近的小瘤。 偶鰭相當細長且有鰭薄膜透明.(參考文獻 40826)
