Maturity: Lm ? range ? - ? cm
Max length : 100.0 cm TL самец/пол неопределен; (Ref. 3265); common length : 50.0 cm TL самец/пол неопределен; (Ref. 3265); наибольший вес (опубликованные данные): 15.0 kg (Ref. 5217)
колючие лучи спинного плавника (общее число) : 1. The head is flattened on top. The snout is short and large and transversally truncated. Mouth terminal, the lower jaw is the same length or slightly longer than the superior jaw. It has three pairs of barbels (1 pair maxillary barbels, 2 pairs of mandibular barbels) (Ref. 35381).
Occurs in coastal waters and river estuaries. Found on shallow muddy bottoms (Ref. 5217). Reproduction seems to occur twice a year, in April and in October. The female lays 20-25 eggs measuring 12-15 mm. Mouth-brooding by the males lasts 10-12 days (Ref. 35381). Marketed fresh and salted (Ref. 5217).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00269 - 0.01023), b=3.11 (2.94 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.9 ±0.5 se; based on size and trophs of closest relatives
устойчивость к внешним воздействиям (Ref.
120179): низкий, минимальное время удвоения популяции 4.5-14 лет (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): High vulnerability (60 of 100).
Nutrients (Ref.
124155): Calcium = 76.8 [40.1, 164.5] mg/100g; Iron = 0.91 [0.56, 1.59] mg/100g; Protein = 16.8 [15.1, 18.6] %; Omega3 = 0.149 [0.084, 0.263] g/100g; Selenium = 63.2 [31.4, 136.4] μg/100g; VitaminA = 24.7 [9.5, 63.3] μg/100g; Zinc = 0.992 [0.662, 1.557] mg/100g (wet weight);
