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..

生態學
海洋 礁區魚類; 深度上下限 42 - 120 m (Ref. 59379), usually 90 - 120 m (Ref. 90102). 熱帶; 12°N - 21°S, 134°E - 178°W
Western Pacific: Marshall Islands southward to Fiji, across the Caroline Islands from Puluwat to Palau, and south to Vanuatu. This species was not observed at Rarotonga (Cook Islands), Kiritimati (Line Islands), nor in American Samoa during brief surveys of deep reefs in these areas.
西太平洋: 馬紹爾群島向南至斐濟,越過從 Puluwat 到帛琉的加羅林群島, 而且南至萬那度。 這種是在拉羅東加 (科克群島) ， Kiritimati(列島群島) 沒有被觀察到, 也不在美屬薩摩亞群島在深礁的簡短調查的時候在這些區域中。

背棘 (總數): 13; 背的軟條 (總數): 13-14; 臀棘 2; 臀鰭軟條: 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).
這種被藉著下列的特徵區別: 背鰭鰭條 XIII,13-14, 通常 14; 臀鰭鰭條 2,15-16; 胸鰭鰭條 18-19, 通常 19; spiniform 尾部的鰭條 2-3, 通常 3; 管狀的側線鱗片 14-16; 鰓耙 6-8+19-22(通常 6-7+19-21; 總計 26-29); 體高 1.57-1.77 分之一標準體長。 顏色新鮮時是灰白的淡紫色-淡色的灰色背面, 腹側灰白的; 從後頸到上尾部的梗背面以金色的邊緣 3 或 4 列的鱗片; 在背鰭的基部鞘上的小鱗片幾乎完全金色; 中央的鰭薄膜淡紫色的灰色或半透明的藍色,佈滿了金色的顏色; 虹膜黃色.(參考文獻 59379)
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.
這種在它的平常環境，陡坡與海峭壁深度大約 90-120 公尺中通常豐富; 通常有小的洞與石灰石碎石堆, 常見於範圍從一個 6 到數十個個體的群集中見到攝取食物的低在水團.(參考文獻 59379)
