简单描述 型态特徵 | 形态测量图

脊椎骨: 116 - 124. Dorsal fin arising well behind pectoral tips; pectoral fins teardrop-shaped; snout very short; jaws elongate; anterior nostril in a very short tube in upper lip, closely followed by an ethmoidal pore, a barbel, and the posterior nostril which is in outer lip and entirely covered by a flap; labial cirri numerous, unbranched and slender in anterior half of lip of mandible, those posterior and along lower lip branched at tips; flesh above and behind eye laterally elevated as a ridge; dorsal head profile notably incised and medially constricted behind eyes, the flesh forming a narrow transverse ridge behind dorsal margin of eyes; head pores and lateral-line pores apparent; free sensory neuromasts visible as rows of small white spots on nape; teeth conical (Ref. 42180). Lateral-line pores and temporal pores typically in dark spots; smaller dark spots present irregularly on flank between lateral line and dorsal fin of larger specimens (Ref. 42180); brownish, lighter below and on fins (Ref. 3972). Eye small, colored like the head, and placed towards the front of the long mouth (Ref. 48635).
出现的背鳍在胸鳍顶端正后方; 胸鳍泪滴-形状的; 吻非常短的; 颚延长; 前鼻孔在上嘴唇中形成一根非常短的管, 接近地跟随着一个筛骨的孔,一个触须与后面的鼻孔在外部的唇中是而且完全地被一个鳃盖盖着; 唇的触须很多的,不分枝的与细长的在下颚的前半部唇中,那些向后与沿着在顶端分枝的下唇; 在眼上面与后面的肉侧面升高作为一个脊; 头部背面轮廓特别地呈锯齿状的而且中间地压缩了形成一个眼的狭窄横跨脊在后上缘的在后眼,肉; 头部孔与侧线孔明显的; 分离的感觉神经瘤看得见的在后颈上形成多列的白色小斑点; 齿锥形.(参考文献 42180) 侧线孔与暂时的孔典型地形成深色的斑点; 比较小的深色斑点不规则地在侧线与较大的标本的背鳍之间的侧面上呈现;(参考文献 42180) 褐色的, 腹面颜色较淡与在鳍上.(参考文献 3972) 眼小的, 色彩类似头部, 而且向长嘴的前面放置.(参考文献 48635)

生物学特性     字汇 (例如 epibenthic)

Generally found in shallow lagoon sand, rock and broken coral substrates at depths of 0-2 m (Ref. 42180). Benthic (Ref. 58302). Occurs in sandy bottoms from intertidal to over 12 m. Remains buried in sand with only the eyes protruding where it waits to ambush fish (Ref. 9710) and octopuses (Ref. 275). Used in Chinese medicine (Ref. 12166).

通常发现于泻湖浅滩沙子,岩石与碎裂的珊瑚底部深度 0-2 公尺了。 (参考文献 42180) 出现于砂质底部从潮间带到超过 12 公尺。 保持埋藏在沙子之中仅仅伸出眼睛在哪里它等候埋伏突袭鱼 (参考文献 9710) 与章鱼.(参考文献 275) 被用于中药材了。 (参考文献 12166)
