簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 10-11; 臀棘 0; 臀鰭軟條: 21 - 24; 脊椎骨: 35 - 37. Diagnosis: Bathyaethiops baka is distinguished from all congeners by an incomplete squamation with the scale cover variably reduced to no pre-dorsal scales, usually no scales on caudal peduncle, and usually a scale-free patch on middle flank at about level of pelvic-fin origin; furthermore distinguished by a unique colour pattern, i.e., a combination of a humeral spot of about pupil-size and the absence of dark vertical bars along midlateral flanks (Ref. 110423). It is difficult to distinguish from juvenile Bathyaethiops caudomaculatus, from which it differs by the usually absence of unicuspid teeth in the second row of lower jaws vs. presence, and usually the absent or rudimentary supraneural between two neural spines directly in front of the first dorsal fin pterygiophore vs. well developed (Ref. 110423).
Found in the main river channel of Ngoko River, usually in or close to riparian vegetation over a substrate of fine particles and organic material (Ref. 110423).
