Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 15 - 16; членистые (мягкие) лучи спинного плавника (общее число) : 9 - 10; колючие лучи анального плавника: 4; членистые (мягкие) лучи анального плавника: 6 - 7. Diagnosis: mouth large and protrusible; premaxilla reaching upwards to level of occipital region; preopercle denticulate; lateral line absent; 5 scale rows on cheeks; caudal fin rounded (Ref. 57397).
Coloration: highly variable, depending, among other factors, on emotional state of fish; normally, ground colour dark brown; iris red; opercula with a large black blotch bordered posteriorly by a bright red band; under stress, colour turns rapidly into a marbled pattern with alternating light and dark brown cross bars; in young individuals, sides show a series of light cross bars (Ref. 57397).
Occurs in running freshwater (Ref. 6801). Maximum TL recorded was 4.8cm (Ref. 6801).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0020 [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): 3.6 ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
