簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 24 - 25; 臀鰭軟條: 40 - 41. Two pectoral rays (one as tiny rudiment), and a barbel with three branches arising proximal to midlength of the stem, followed by two ovoid swellings (bulbs), either contiguous or separated, and a large terminal bulb. The tear-shaped terminal bulb larger in diameter than the stem or proximal bulbs, with the acuminate end posteriad and upturned dorsally, and bears multiple filaments and bulblets in two groups, one at its anterodorsal surface and one at its terminus. Barbels relatively short (<= 20% standard length) (Ref. 51076).
二個胸鰭鰭條 (一如極小的原基), 與一個觸鬚有三條出現的分支接近也被跟隨著二個卵形的膨脹 (球莖) 的莖的身體中央鄰近的或者分開, 與一個大的末端球莖。 淚滴-形狀的末端球莖較大的直徑超過莖或近端的球莖, 藉由銳利的末端 posteriad 與朝上的背面, 而且在二個群有多個絲狀突起與球莖, 一在它的終點的它的前背部表面與他。 觸鬚相當短的 (<=20% 標準長度).(參考文獻 51076)
Probably undergoes some form of vertical migration from below 500 m during the day and within the upper 100 m at night (Ref. 51076).
可能歷經一些形式的垂直性迴游從下方 500 公尺在白天期間與在上面的 100 公尺裡面在晚上.(參考文獻 51076)
