deskripsi pendek Morfologi | Morfometrik

duri punggung lunak (Keseluruhan (total)): 10; Sirip dubur lunak: 21 - 23; vertebrata, bertulang belakang: 38. Distinguished from all other species of Knodus by the presence of thickened skin forming folds covering the basal portion of the six anteriormost branched anal-fin rays and its interradial membrane. Differs also uniquely among its congeners by having the six anteriormost branched rays associated with more developed skin considerably thicker than that on the remaining anal-fin rays. Can be differentiated also from all congeners, except Knodus meridae, by the low number of branched anal-fin rays (14-16 vs. more than 17), by the presence of relatively compressed teeth (vs. teeth bulky in remaining Knodus and Bryconamericus species, with the exception of Bryconamericus deuteronoides), and the presence of a broad, silvery-gray midlateral stripe (midlateral stripe in remaining Knodus and Bryconamericus species relatively narrow) (Ref. 75965).

Found only in areas of moderate to strong current and present even in the torrential flow of waterfalls. Juveniles measuring up to 2.4 cm SL occur at sandbars marginal to waterfall pools. Feeds only on Chironomidae larvae based on 3 stomach contents (Ref. 75965).

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.4 se; based on size and trophs of closest relatives
Daya lenting (Ref. 120179):  Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
