Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 32 - 34; Anal spines: 2; Anal soft rays: 7. Colour dark greyish above, yellowish to pale below. Pectoral fins long and jet black. Tips of pelvic and anal fins dark. Inside of gill cover black. Eye small, about 8 to 9 times in head length. Mouth small, inferior, enclosed under snout. Chin with 5 pores and many barbels, 3 to 4 pairs in a tuft around median mental pore, 15 or 16 pairs along median edges of lower jaws and subopercles. Pectoral fins greatly enlarged, extending beyond anal-fin base. Gas bladder narrow, about equal to head length, bearing anteriorly 2 pairs of appendages, anterior pair short and horn-like, lateral pair long, tube-like, extends to posterior end of gas bladder (Ref 51721).

Biology     Glossary (e.g. epibenthic)

Found over mud or mud-sand bottoms of estuaries and adjacent areas (Ref. 5217). Feeds on bottom-dwelling organisms, mainly worms. Marketed fresh and salted.

Estimates based on models

Preferred temperature (Ref. 123201): 27 - 28.3, mean 27.5 °C (based on 362 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00851 (0.00413 - 0.01752), b=3.08 (2.91 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.31 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (22 of 100).
Price category (Ref. 80766):   Medium.
