Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 1; членистые (мягкие) лучи спинного плавника (общее число) : 7; членистые (мягкие) лучи анального плавника: 7. Distinguished from all its congeners, except Corydoras reynoldsi and C. weitzmani, by its color pattern consisting of three large, dark blotches, the first one "mask" on the head, across the eye, the second one on the trunk at the level of the dorsal fin, and the third one on the trunk at the level of the adipose fin. Differs further from C. reynoldsi mainly by the development of trunk blotches; and from C. weitzmani by the presence of a dusky saddle between the dorsal and adipose fin, the second trunk blotch extending vertically from the adipose-fin base to the anal-fin base, and the presence of four dark, vertical stripes in the caudal fin (Ref. 51470).
Facultative air-breathing (Ref. 126274)

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02239 (0.00916 - 0.05471), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): высокий, минимальное время удвоения популяции до 15 месяцев (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
