Short description
Morfologia | Morfometria
Spine dorsali (totale): 1; Raggi dorsali molli (totale): 7; Spine anali 0; Raggi anali molli: 17 - 21; Vertebre: 49 - 50. Teeth strong, non-depressible; in narrow bands in jaws and in four patches arranged across front palate. Snout prominent, jaw teeth exposed; mouth wide. Head somewhat venulosus, head shield almost smooth. Eye small, free of head skin, 6-14% HL. No rakers on posterior face of first two arches; gill opening wide. Body orange-yellow; lips, inside mouth and body usually covered with orange or yellow mucus, and teeth usually reddish (Ref. 40908).
Inhabits coastal and lower mangrove areas, estuaries into main rivers and lagoons (Ref. 40908, 75154).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5625 [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): 3.8 ±0.4 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Molto basso, tempo minimo di raddoppiamento della popolazione più di 14 anni (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Very high vulnerability (88 of 100).
