Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 2; Anal soft rays: 8; Vertebrae: 24. This species is distinguished by having D VI-I,9; A II,8; pectoral rays 13; lateral line scales 24; predorsal scales 5; gill rakers 7 or 8+20 or 21, excluding an indistinct rudiment on upper limb; preopercular margin serrate; preopercular ridge smooth; body depth 3.4-3.7 in SL; semi-transparent in life with golden-brown midlateral strip, bordered below by narrow silver stripe; tip of lower jaw blackish (Ref. 11893).

Biology     Glossary (e.g. epibenthic)

Occurs in silty inshore reefs; aggregations observed hovering during the day around both soft and hard coral formations. An oral brooding male collected at Madang, papua New Guinea, contained 328 eggs, which is a relatively low number for the genus (Ref. 11893).

Estimates based on models

Preferred temperature (Ref. 123201): 28 - 29.2, mean 28.8 °C (based on 1005 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00201 - 0.01253), b=3.26 (3.04 - 3.48), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.4 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).
Nutrients (Ref. 124155):  Calcium = 252 [124, 510] mg/100g; Iron = 1.23 [0.62, 2.20] mg/100g; Protein = 18.4 [17.2, 19.6] %; Omega3 = 0.107 [0.052, 0.233] g/100g; Selenium = 33.1 [12.6, 80.4] μg/100g; VitaminA = 91.8 [26.0, 309.9] μg/100g; Zinc = 2.76 [1.67, 4.26] mg/100g (wet weight);
