Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8. This species is distinguished by the following characters: absence of a black spot/blotch at rear of first dorsal fin; D2 I,8; A I,8-9; pectoral fin rays 17-18; scales in lateral series 25-28; predorsal scales ctenoid 6-7; gill rakers short and stout 2+8; suborbital rows of sensory papillae with rows a and c in reduced and disorganised transverse pattern (Ref. 119377).

Biology     Glossary (e.g. epibenthic)

This species was observed in vegetated [Lessepsian seagrass Halophila stipulacea (Forsskål) Ascherson, 1867] soft bottom and sloping habitats and also prefers areas where the water movement is limited, such as in sheltered bays. Populations were observed at 5-20 m depth but were more abundant at 7-15 m depth with approximately 1-3 individuals per sq.m (Ref. 119377).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = No PD50 data   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
