Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 72 - 84; Anal soft rays: 62 - 70. Body and fins darkly marbled and with irregular white blotches. Head rectangular dorsally; snout small; eyes dorsally located. Frontal fontanelle intermediate between `sole-shaped' and `knife-shaped'; occipital fontanelle very small. Supraorbital and `dermosphenotic' bones joined in specimens above 57.6 mm SL. Gill rakers relatively long, slender and distantly set. Degree of development of the suprabranchial organ variable, generally greatly reduced. Openings of the secondary sensory canals hardly visible.

Facultative air-breathing (Ref. 126274); Nothing is known about the ecology and reproduction of this species (Ref. 78218).

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).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
