Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 76-79; Raggi anali molli: 60 - 67; Vertebre: 40 - 41. The species is distinguished by the following: Vertebrae 11+29-30=40-41, dorsal fin rays 76-79, anal fin rays 60-67; small eyes (1.6-2.1% SL); outer pseudoclasper moderately large, wing- shaped, slightly bent outwards; inner pseudoclasper almost free, bifurcate, with stout hook-like anterior branch and broad flap-like posterior branch; scale patch on cheek with 6-7 rows of small scales on upper cheek, 2 large scales on operculum above opercular spine; head massive, broad; otolith length to height ratio 2.1. This is the only species of the genus which combines small eyes (about 2.1% SL) with presence of scales on the operculum (Ref. 57884).

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=0.00447 (0.00175 - 0.01142), b=3.10 (2.88 - 3.32), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.2 ±0.5 se; Based on size and trophs of closest relatives

Resilienza (Ref. 69278): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (15 of 100) .
