简单描述
型态特徵 | 形态测量图
背棘 (总数): 6 - 8; 背的软条 (总数): 4-5; 臀棘 44-58; 臀鳍软条: 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).
尾部细长的而且渐渐变细成一个尖点。 嘴下方的，小的与像吸管一样的; 上嘴唇有厚的,打褶摺层; 颚骨的后端弯曲锐利向下, 形成一个盖状的结构; 在毗邻上嘴唇的吻部上的肉质的乳突。 齿不存在。 背鳍基底短的, 位于肛门上方, 第一个 4-6个鳍条硬而刺状的, 从前面到背面长度一直增加, 其余的柔软与分段的, 连接所有的鳍条薄膜第一个除了 I-III 棘。 臀鳍长的, 从在肛门正后方到尾尖，前面的硬棘延伸, 在后部的鳍条片段, 转变逐渐的。 尾鳍不存在。 (参考文献 11041) 鳃盖鳃盖的淡褐色，鳃室内壁与边缘深褐色的, 嘴与喷水孔内壁淡的黄褐色.(参考文献 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样的嘴底部沉淀物中的有机物质 [RF 怀疑这是一个碎屑捕食者; 没有齿的精细的嘴从地面为吸取状似一个特别化身体柔软的底栖性无脊椎动物; 同时, 有没有鳃耙过滤碎屑 (参考文献 50674)]. 没有明显的性同种二形; 37.5 公分 SL 的一条母鱼仍然是不成熟的。 (参考文献 50674)
