Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 25.0 cm SL maschio/sesso non determinato; (Ref. 1602)
Spine dorsali (totale) : 13; Raggi dorsali molli (totale) : 10 - 11; Spine anali: 3; Raggi anali molli: 6 - 7. Body reddish with 5 dark bars, alternating with thin dark bars in large specimens; median fins with small dark spots; dark spot on cheek (Ref. 4313). Mid-dorsal spines longer than body depth (Ref. 37816).
Found on coral, rubble, or rock bottoms of reef flats (Ref. 9710); also in coastal to outer reef habitats in sheltered lagoons and in caves, sometimes in small aggregations. Usually shallow, from 3-60m (Ref. 30874) but also reported to 80 m depth. Pelagic stages travel great distances and expatriate to sub-tropical zones (Ref. 48635). Spawned in captivity (Ref. 37816). Spines with poison glands (Ref. 125576).
Life cycle and mating behavior
Maturità | Riproduzione | Deposizione | Uova | Fecundity | Larve
Spawn in pairs. Courtship and spawning occur at night. Males aggressive, females are smaller and develop almost white face when in courtship. Spawning occurs at the apex of a short and rapid paired ascent resulting in a gelatinous mass of 2,000 to 15,000 eggs. Hatching occurs 36 hours later and larvae settle out in a few weeks at a size of 10-12 mm.
