簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 6 - 8; 背的軟條 (總數): 4-5; 臀棘 44-58; 臀鰭軟條: 67 - 88; 脊椎骨: 228 - 234. Tail slender and tapering to a point. Mouth inferior, small and sucker-like; upper lip with thick, pleated folds; posterior end of maxilla bent sharply downward, forming a flap-like structure; fleshy papillae on snout bordering upper lip. Teeth absent. Dorsal fin short-based, located above anus, the first 4-6 rays hard and spinous, increasing in length from front to back, the remainder soft and segmented, membrane connecting all rays except for first I-III spines. Anal fin long, extending from just behind anus to tip of tail, anterior rays spinous, posterior rays segmented, the transition gradual. Caudal fin absent (Ref. 11041). Light brown, lining of gill chamber and rim of opercular branchiostegal flap dark brown, mouth and lining of buccal cavity light yellowish tan (Ref. 37108).
尾部細長的而且漸漸變細成一個尖點。 嘴下方的﹐小的與像吸管一樣的; 上嘴唇有厚的,打褶摺層; 顎骨的後端彎曲銳利向下, 形成一個蓋狀的結構; 在毗鄰上嘴唇的吻部上的肉質的乳突。 齒不存在。 背鰭基底短的, 位於肛門上方, 第一個 4-6個鰭條硬而刺狀的, 從前面到背面長度一直增加, 其餘的柔軟與分段的, 連接所有的鰭條薄膜第一個除了 I-III 棘。 臀鰭長的, 從在肛門正後方到尾尖,前面的硬棘延伸, 在後部的鰭條片段, 轉變逐漸的。 尾鰭不存在。 (參考文獻 11041) 鰓蓋鰓蓋的淡褐色,鰓室內壁與邊緣深褐色的, 嘴與噴水孔內壁淡的黃褐色.(參考文獻 37108)
Feed mostly on organic material contained in bottom sediment drawn up by the sucker-like mouth [RF doubts this is a detritus feeder; the elaborate mouth without teeth looks like a specialization for extracting soft-bodied benthic invertebrates out of the ground; also, there are no gill rakers to filter detritus (Ref. 50674)]. No obvious sexual dimorphism; a female of 37.5 cm SL was still immature (Ref. 50674).
大部分吃汲取藉由像吸管一樣的嘴底部沉澱物中的有機物質 [RF 懷疑這是一個碎屑捕食者; 沒有齒的精細的嘴從地面為吸取狀似一個特別化身體柔軟的底棲性無脊椎動物; 同時, 有沒有鰓耙過濾碎屑 (參考文獻 50674)]. 沒有明顯的性同種二形; 37.5 公分 SL 的一條母魚仍然是不成熟的。 (參考文獻 50674)
