Short description Morphology | Morphometrics

Anal spines: 0; Anal soft rays: 9 - 12; Vertebrae: 43 - 47. Diagnosis: tooth patches broad (Ref. 34006, 44050). Pectoral fin placed ventrally; 8-12 anal-fin rays; 19 caudal-fin rays (ii-7-8-ii); 43-47 vertebrae (Ref. 44050). Body and head marked with large blotches (Ref. 34006, 44050). Spotting and blotching concentrated posteriad; caudal and anal fins unmarked or lightly spotted; paired fins rarely spotted (Ref. 44050).

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=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.4 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  .
Vulnerability (Ref. 59153):  High vulnerability (59 of 100) .
Price category (Ref. 80766):   Unknown.
