背的軟條 (總數) : 25; 臀鰭軟條: 36; 脊椎骨: 69. A single terminal bulb, more than twice its width, with a single, digitate terminal projection 40-110% of bulb length. Bulb and projection combined 2-3.4% SL. Barbel 28-41% SL in small specimens, 60-76% SL in those over 85 cm SL. Axis of stem well pigmented. External chevron-shaped or roundish striated areas unpigmented, closely spaced or contiguous distally, but often obscured distally by inclusions. Spherical or granular inclusions present in distal half of stem, small and widely-spaced proximally, becoming large and crowded distally; inclusions not well developed in specimens smaller than about 10 cm SL. Middorsal paired spots between occiput and dorsal-fin origin 8 (Ref. 11333).
一個末端的球莖, 超過兩次它的寬度,具有一個單個 digitate 終點突出 40-110% 的球莖長度。 球莖與突出聯合了 2-3.4% SL 。 在小的標本中的觸鬚 28-41% SL, 在那些超過 85 公分 SL 中的 60-76% SL。 莖的軸很好地有顏色。 外部的鋸齒形或圓的有條紋的區域沒有顏色, 間隔很密的或鄰近的末梢部地, 但是時常末梢部地被包含陰暗。 圓球狀或表面粗糙的包含出現在末梢部一半的莖, 小而空隙大的近端地, 末梢部地變成大而且擁擠; 包含不在比大約 10 公分 SL 小的標本中的發展良好的。 在後腦部與背鰭起點 8 之間的背面中央的成對斑點.(參考文獻 11333)

Estimates based on models
Preferred temperature (Ref.
