Western Central Pacific: Fiji, Great Barrier Reef, New Caledonia and Tonga.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.6 cm SL male/unsexed; (Ref. 36585)
Dorsal spines (total): 7; Dorsal soft rays (total): 10 - 12; Anal spines: 1; Anal soft rays: 9 - 10; Vertebrae: 26. Two oblique pigment bars on the head posterodorsal to the eye. Uniquely derived lower jaw, modified anteromedially into a dentigerous, fleshy projection and a row of elongate, transversely oriented papillae in the ventral portion of the cheek. Interopercular-isthmus groove nearly straight. Caudal fin rounded.
Facultative air-breathing in the genus (Ref. 126274); Found in association with Acropora loripes and Acropora elseyi; commonly in pairs (Ref. 36585); a coral-commensal species (Ref. 72446). Feeds on copepods, forams, and unidentifiable flocculent material (may represent in part the remains of coral tissue) (Ref. 36585).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.3 ±0.25 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
