Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 65 - 81; Rayons mous anaux: 51 - 62; Vertèbres: 57 - 62. Diagnosis: head oval-shaped to rectangular dorsally; snout broadly rounded; eyes more laterally placed; frontal fontanelle extremely long and narrow; occipital fontanelle oval-shaped to rounded; tooth plates extremely broad (Ref. 248). Supraorbital and `dermosphenotic' bones separated; dermosphenotic somewhat reduced and shows a clearly marked notch (Ref. 248, 101841) although this notch is not observed in all specimens (Ref. 101841). Pectoral spine straight and robust; gill rakers relatively long and distantly set; openings of the secondary sensory canals regularly arranged (Ref. 248). Suprabranchial organ reduced to virtually absent (Ref. 248, 101841). Colouration: preserved fish show uniform colouration: dorsum, flanks and upper side of paired fins dark brown; ventrum and ventral parts of paired fins light grey to beige; no information known on colouration of living specimens (Ref. 248).

Facultative air-breathing (Ref. 126274)

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00776 (0.00343 - 0.01757), b=2.97 (2.79 - 3.15), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.5 se; based on size and trophs of closest relatives

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).
