Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 73 - 76; Anal soft rays: 56 - 61; Vertebrae: 41. The species is distinguished by having the following characters: Vertebrae 11+30=41, dorsal fin rays 73-76, anal fin rays 56-61; small eyes (1.5-2.1% SL); outer pseudoclasper with small ear-lobe extension opening inwards; inner pseudoclasper free from outer pseudoclasper, with supporter, forming a sharp, forward-inclined thorn; narrow scale patch on cheek, absence of scales on operculum; head profile slender; otolith length to height ratio 2.0-2.2 (Ref. 57884).

Solitary inhabitant of coral reef crevices, cryptic (Ref 90102).

Estimates based on models

Preferred temperature (Ref. 123201): 26.2 - 27, mean 26.5 °C (based on 5 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).
