Morphology | Morphometrics
soft rays: 8. This species is distinguished by the following characters: D1 VII, D2 I,9; A II,8; pectoral fin rays 14-16; tubed lateral-line scales 20-24; median predorsal scales 4 (rarely 3 or 5); total gill rakers 2-4 + 8-10 = 11-14; developed gill rakers 1 + 7-9; gill rakers on ceratobranchial 7-8; body depth 2.3-2.7 in SL and body width 1.9-2.2 in the depth; eye diameter 2.6-3.5 in HL; first dorsal spine 2.4-4.6 in second spine; second dorsal spine 3.7-6.6, second dorsal fin spine 3.7-5.4, second anal spine 5.0-7.0, all in head length; pectoral-fin length 4.2-5.3 and pelvic-fin length 4.2-4.7 in SL; caudal peduncle length 1.5-2.1 in distance between pelvic spine insertion and anal-fin origin; preopercular edge with 23-35 serrations, the preopercular ridge smooth; scales mostly spinoid, but some cycloid scales on anterior part of body; vomer and palatines with 1-2 series of small teeth, but palatines sometimes toothless; tip of light organ on each side of tongue bound by membrane (Ref. 90035).
Found in coastal reefs and outer reef lagoons. This species forms small groups with long-spined urchins (Ref. 48635) (e.g. Diadema setosum in shallow sheltered waters, Ref. 1602); but was also found among the spines of Acanthaster planci (Ref. 90035). Feeds on zooplanktons and small invertebrates (Ref. 89972).
