Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 64 - 72; Anal soft rays: 49 - 54; Vertebrae: 39 - 41. The species is distinguished by the following characters: vertebrae 11 + 28-30 = 39-41, dorsal fin rays 64-72, anal fin rays 49-54; outer pseudoclasper is broad, wingshaped with single curved supporter; inner pseudoclasper with three lobes, consisting of a branched supporter, anterior branch curved and long, posterior branch short, and a thick fleshy lobe in between; penis with no abrupt change in thickness; opercular spine with single, sharp tip in small specimens and bi- or tri-furcated in specimens > 45 mm SL; scale patch on cheeks is broad, with 8-10 vertical scale rows; otolith length: height ratio 2.2 (Ref. 57883).

Estimates based on models

Preferred temperature (Ref. 123201): 24.3 - 29.1, mean 26.9 °C (based on 190 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).
