Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 11; Dorsal soft rays (total): 10 - 12; Anal spines: 3; Anal soft rays: 8 - 9. This species is distinguished by the following characters: D XI-XII, 10-12; A III, 8-9; scale rows between the fifth dorsal-fin spine base and lateral line 3.5; cheek scale rows 3-4; body rounded; ventral infraorbital series above posterior part of upper jaw changing with growth from almost straight to weakly concave; second anal-fin spine robust and dull pointed; upper and lower jaws with thin lips,
especially anteriorly; broadly rounded rostral-most head squamation with ca. 10 somewhat smaller scales anteriorly; with growth, prominent ridge developing just before eye and dorsal head profile becoming slightly convex from snout to just above eye; upper and lower molar teeth strongly developed and
flattened on both sides, gradually more molariform posteriorly; upper molars in 3 or 4 rows anteriorly and 4 or 5 posteriorly, rows generally irregular, outer third row distinctly larger; lower molars in 3 or 4 rows anteriorly and 2 or 3 rows posteriorly, rows generally irregular, with innermost row largest posteriorly (outer second row gently curved outward); colour of head and body mostly black, sharply demarcated from whitish belly and chin; a dark spot at top of pectoral-fin base (Ref. 57874).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00870 - 0.04578), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (16 of 100).
