Short description Identification keys | Morphology | Morphometrics

Vertebrae: 119 - 130. This species is distinguished by the following characters: presence of pectoral fin; dorsal-fin origin is slightly anterior to pectoral-fin base, predorsal length 10.7-13.1% TL; anus anterior, below tip of pectoral fin, preanal length 15.9-18.9% TL; very short trunk, 2.8-5.5% TL; intermaxillary teeth 2; compound teeth on vomer 4; single row of 9-11 large compound teeth on lower jaw; head pores: IO 4, SO 3; M 6; POP 0; AD 1, F 0, ST 0; lateral-line pores: predorsal 3-6, prepectoral 6-9, preanal 8-12, total 57-75, the last at posterior two-thirds of total length; MVF 8-14-124, total vertebrae 119-128 (up to 130 in Robins & Robins, 1989) (Ref. 106136).

Inhabits coastal waters. Prefers muddy bottoms, often off mouths of large rivers.

Estimates based on models

Preferred temperature (Ref. 123201): 17.2 - 27.6, mean 23.6 °C (based on 944 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.4 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).
