Etymology: Clarias: Greek, chlaros = lively, in reference to the ability of the fish to live for a long time out of water.
Eponymy: Carolus Franciscus Sala (1839–1881) was a Dutch soldier and collector. [...] (Ref. 128868), visit book page.

背棘 (总数) : 0; 背的软条 (总数) : 79 - 93; 臀棘: 0; 臀鳍软条: 67 - 79; 脊椎骨: 63 - 68. Diagnosis: typical extremely elongate, eel-shaped body (maximum body depth 8.7-13.9% of standard length); head length 20.2% SL (Ref. 57129). Head rather rectangular in dorsal outline; snout broadly rounded; eyes more dorsally located; frontal fontanelle intermediate between "knife-shaped" and "sole-shaped"; occipital fontanelle broadly oval-shaped; "dermosphenotic" and supraorbital bones are joined; tooth plates relatively small; premaxillary longer than vomerine (Ref. 248). Distance between occipital process and dorsal-fin base relatively large (8.3-12.4% of standard length); dorsal and anal fins (67.7-75.0% and 50.6-58.9%, respectively, of standard length) very long and sometimes partially confluent with caudal fin (Ref. 57129). Pectoral spine serrated on both sides (Ref. 248, 57129). Gill rakers long and distantly set (Ref. 248).
Coloration: fresh specimens dark brown on back; sides marked with irregular blackish spots, belly light brown to beige; a vertical bar may be present on caudal fin (Ref. 57129). Flanks with vertical rows of small white spots (Ref. 248, 57129).
头部相当矩形在背部的轮廓中; 吻宽广地圆的; 眼位于更背面。 额骨囱门介于之间刀状的 '与唯一的 - 形状的'; 后头骨囱门宽广椭圆形。 那皮蝶骨的' 与上眼窝骨合并在一起。 齿板相当小的; 上颌骨前的长度超过犁骨。 背鳍与臀鳍不真实地与尾鳍汇和鳍。 胸棘在两边上锯齿状的了。 鳃耙长的而且远远地竖立。 呈现在侧面上的白色的垂直列的第二感觉管的开口
Facultative air-breathing (Ref. 126274); Occurs in river systems which arise in mountainous areas and are entirely within the rain forest (Ref. 248). Very little is known about the biology, but on basis of its distribution the species appears to be restricted to the rain forest (Ref. 78218).
出现于在多山的区域中出现而且在雨森林里面是完全地的河流域。 (参考文献 248)
