Épines dorsales (Total) : 13; Rayons mous dorsaux (Total) : 13 - 15; Épines anales: 3; Rayons mous anaux: 6 - 7; Vertèbres: 26. Head spines strong to moderate - nasal, preocular, postocular, tympanic and parietal spines present, nuchals usually absent, supraocular and coronal spines absent (Ref. 27437). Weak symphyseal knob; 2nd anal fin spine longer than 3rd (Ref. 27437). Caudal fin moderately indented (Ref. 6885). Pink to red with irregular dark markings interrupted by lighter band along two thirds of lateral line; caudal fin with dark membranes and pink or red band terminating fin; anal fin has black between 2nd and 3rd spines; tip of spinous dorsal black (Ref. 27437).

Viviparous (Ref. 34817). Too small to be of high commercial value (Ref. 27437).

Estimates based on models

Preferred temperature (Ref. 123201): 3.7 - 7.1, mean 5.2 °C (based on 28 cells).

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

Bayesian length-weight: a=0.01000 (0.00499 - 0.02004), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.7 ±0.5 se; based on size and trophs of closest relatives

Generation time: 8.0 ( na - na) years. Estimated as median ln(3)/K based on 2 growth studies.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (tmax=47).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).

Catégorie de prix (Ref. 80766): Medium.
