Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 71 - 82; Anal soft rays: 58 - 69; Vertebrae: 43 - 45. The species is distinguished by the following characters: vertebrae 11 + 32-34 = 43-45, dorsal fin rays 71-82, anal fin rays 58-69; eyes large (2.3-2.8% SL); outer pseudoclasper moderately large, broad, wing-shaped, with tip slightly bent outwards, with a characteristic kink at the base seen from ventral view; inner pseudoclasper bifurcate, both branches of about equal length, broad based, flap-like; narrow scale patch on cheek with 4-5 scale rows, no scales on operculum; head short, with blunt snout; otolith thick with gently curving dorsal rim (Ref. 57884).

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29.3, mean 27.4 °C (based on 239 cells).

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

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
