Description synthétique Morphologie | Morphométrie

Épines dorsales (Total): 0; Rayons mous dorsaux (Total): 74-87; Rayons mous anaux: 57 - 67; Vertèbres: 60 - 62. Diagnosis: tooth plates extremely narrow (Ref. 248, 57129). Vomerine tooth plate very long (Ref. 248), its length almost twice that of the premaxillary plate (Ref. 57129). Width of premaxillary plate 21.5-26.2% of head length, width of vomerine plate 19.0-22.8% of head length, length of vomerine plate 5.2-8.6% of head length (Ref. 57129). Head short and rounded in dorsal outline; eyes relatively large and dorsally located; frontal fontanelle very small, short and squat (`sole-shaped'); occipital fontanelle small and oval-shaped; "dermosphenotic" and supraorbital bones joined by a common suture, except in a specimen of 27 mm SL; pectoral spine robust and slightly curved; openings of secondary canals along lateral line appear as irregular white spots on body (Ref. 248). Coloration: no information on colour in life (Ref. 57129). Preserved specimens show 2 types of colouration: uniform, with back and sides dark brown and belly lighter; and marbled, with irregular brownish spots against a light background on back and sides, and belly whitish (Ref. 57129). Dorsal and anal fins white-edged (Ref. 57129).

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=0.00676 (0.00366 - 0.01249), b=3.03 (2.87 - 3.19), in cm total length, based on LWR estimates for this species & 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 (22 of 100).
