Etymology: Azurina: Latin, azurinus = blue, pale blue; the name of Leuciscus caeruleus, blue Roach; 1600 (Ref. 45335); brevirostris: Name from Latin words 'brevis' meaning short and 'rostrum' for beak or snout, referring to the very short snout of this species relative to other species in the genus.

marino asociado a arrecife; rango de profundidad 42 - 120 m (Ref. 59379), usually 90 - 120 m (Ref. 90102). Tropical; 12°N - 21°S, 134°E - 178°W

Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 13; Radios blandos dorsales (total) : 13 - 14; Espinas anales: 2; Radios blandos anales: 15 - 16. This species is distinguished by the following characters: Dorsal rays XIII,13-14, usually 14; anal rays II,15-16; pectoral rays 18-19, usually 19; spiniform caudal rays 2-3, usually 3; tubed lateral-line scales 14-16; gill rakers 6-8 + 19-22 (usually 6-7 + 19-21; total 26-29); body depth 1.57-1.77 in SL. Color when fresh is pale lavender-tinged gray dorsally, paler ventrally; 3 or 4 rows of scales dorsally from nape to upper caudal peduncle with gold edges; small scales on basal sheath of dorsal fin almost entirely gold; median fin membranes lavender gray or translucent blue, suffused with gold color; iris yellow (Ref. 59379).
Body shape (shape guide): short and / or deep.
Adults are generally abundant in their usual environment, steep slopes and drop-offs at depths of about 90-120 m; usually with small holes and limestone talus, often in aggregations ranging from 6 to several dozen individuals seen feeding low in the water column (Ref. 59379). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Minimum range from Ref. 82433, where this species was found together with Chromis unipa.
