deskripsi pendek Morfologi | Morfometrik

duri punggung lunak (Keseluruhan (total)): 11-12; Sirip dubur lunak: 9; vertebrata, bertulang belakang: 36. Is uniquely diagnosed by the presence of 10 to 14 oblique bars on the sides of the body, extending posteroventrally from the lateral line and independent of the 8 or 9 dorsal transverse bars which are usually present in species of Characidium. Is also distinguished from other species of Characidium from southern Brazil, except C. pterostictum, by the spotted caudal fin. From C. pterostictum, it is easily distinguished by the number (12) of series scales around the caudal peduncle (14 in C. pterostictum). Fourth ray of pectoral fin ray longest, not reaching or just reaching to pelvic fin origin. Third or fourth ray of pelvic fin longest, reaching area between anal opening and anal fin origin (Ref. 27672).

All specimens collected were from middle courses of medium-sized rivers with rocky and muddy bottoms and moderate to strong water current (Ref. 27672).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

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): 3.4 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
