Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 23 - 26; Anal spines: 3; Anal soft rays: 23 - 26. Body uniformly brown to dark brown; caudal fin pale in color (snow white in live fishes). Small, dark spot below and adjacent to axil of pectoral fin. Anterior gill rakers 15-18; posterior 14-16. Snout length 7.9 to 8.2 times in SL. Least depth of caudal peduncle 2.2 to 2.5 times in head length (Ref 9808).

Biology     Glossary (e.g. epibenthic)

This occasionally schooling species occurs in steep outer reef slopes and drop-offs (Ref. 1602, 48637). Benthopelagic over coral and sand (Ref. 58302). Feeds on zooplankton, particularly large gelatinous forms, and on fish eggs and crustaceans (Ref. 1920). Minimum depth reported taken from Ref. 128797.

Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 28.8, mean 27.6 °C (based on 1218 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.41 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
