Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 0; членистые (мягкие) лучи спинного плавника (общее число) : 69 - 80; членистые (мягкие) лучи анального плавника: 59 - 64. Head oval-shaped dorsally; snout broadly rounded; eyes laterally placed. Frontal fontanelle is long and narrow; occipital fontanelle small and oval-shaped. Supraorbital and `dermosphenotic' bones partially reduced (especially the latter) and distantly set. Pectoral spine short and straight; outer side with strong downward serrations. gill rakers short and distantly set. Suprabranchial organ greatly reduced. Openings of the secondary sensory canals display a regular pattern.
Facultative air-breathing (Ref. 126274)

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00794 (0.00357 - 0.01766), b=2.96 (2.78 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.5 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).
