Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 10; Anal spines: 1; Anal soft rays: 9; Vertebrae: 26. This species is distinguished by the following characters: colouration pattern: semitranslucent greyish with a bifurcate white stripe straddling the spinal column, back with a narrow brown stripe extending from the side of the nape to the caudal peduncle, and a wider brown stripe on the ventral part of the body extending from the pectoral-fin axil to the caudal peduncle; some smaller individuals (less than about 2.0 cm SL) have a strong yellow tint on the head and body, and lack the dorsal-most brown stripe on the side; differs from most of its congeners in having a relatively low number of pectoral-fin rays 15-17, usually 16; D VI+I,10; A I,9 (rarely I,8); branched caudal-fin rays usually 15 (sometimes 14, especially specimens < 16 mm SL), anterior dentary has a single enlarged canine posterior to the main band of smaller teeth, and the aperture of the genital papilla reaching or nearly reaching anal-fin origin when adpressed (Ref. 125637).
Facultative air-breathing in the genus (Ref. 126274); Occurs in lagoon coral reefs, sheltering among dense branches of Acropora corals, especially A. longicyanthus (Ref. 125638).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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): 3.2 ±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).
