Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 70-86; Anal soft rays: 54 - 71; Vertebrae: 58 - 65. Diagnosis: head relatively long (Ref. 248, 57129) and flattened [head length 24.8-28.6 % (m = 26.2) of standard length](Ref. 57129). Frontal fontanella short and wide (Ref. 57129), "sole-shaped" (Ref. 248). Lateral cephalic bones (dermosphenotic and supraorbital) becoming contiguous already in young individuals (between 70 and 80 mm SL)(Ref. 248, 57129). First gill arch with 11-19 gill rakers (Ref. 57129). Color pattern usually uniform, occasionally a marbled pattern consisting of various dark brown spots on a light-brown background; head broad and pointed in dorsal outline; tooth plates broad; suprabranchial organ well developed although not completely filling the chamber (Ref. 248). Coloration: no information on colour in life (Ref. 57129). Most preserved specimens uniformly coloured: back and sides light to dark brown, belly beige-white (Ref. 57129). Some specimens have a marbled pattern, with numerous black spots against a lighter background on back and sides, while the belly is beige to yellowish (Ref. 57129).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00724 (0.00336 - 0.01560), b=2.99 (2.82 - 3.16), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.5   ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec < 10,000).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100) .
Price category (Ref. 80766):   Unknown.
