Etymology: Chromis: Greek, chromis = a fish, perhaps a perch (Ref. 45335); circumaurea: Name from Latin words 'circum' meaning round and 'aurea' for golden, of gold, for the golden-yellow coloration of its anal fin, caudal fin, and outer margin of the dorsal fin.
Environment: milieu / climate zone / depth range / distribution range
生態學
海洋 礁區魚類; 深度上下限 111 - 130 m (Ref. 128797). 熱帶; 21°N - 6°N, 137°E - 164°E
Western Pacific: Yap I. (Caroline Islands, Micronesia) and probably in the Marshall and Mariana islands.
西太平洋: 狂吠 I.(加羅林群島, 密克羅尼西亞) 與可能在馬紹爾群島與馬里亞納群島中。
大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 10.2 cm SL 雄魚/尚未辨別雌雄; (Ref. 59379)
背棘 (總數) : 14; 背的軟條 (總數) : 12 - 13; 臀棘: 2; 臀鰭軟條: 13 - 14. This species is distinguished by the following characters: Dorsal rays XIV,12-13, usually 13; anal rays II, 13-14, usually 13; pectoral rays 18-19; spiniform caudal rays 3; tubed lateral-line scales 16-17; gill rakers 6-7 + 20-21, total 26-27; body depth 1.68-1.86 in SL. The color when fresh is mahogany brown with bright yellow distally on spinous portion of dorsal fin; the soft portion of dorsal fin, caudal fin, and anal fin is bright yellow.
這種被藉著下列的特徵區別: 背鰭鰭條 XIV, 12-13, 通常 13; 臀鰭鰭條 2,13-14, 通常 13; 胸鰭鰭條 18-19; spiniform 尾部的鰭條 3; 管狀的側線鱗片 16-17; 鰓耙 6-7+20-21,總計 26-27; 體高 1.68-1.86 分之一標準體長。 顏色新鮮時是赤褐色的褐色有鮮黃色的末梢部地在背鰭的刺狀部分上; 背鰭，尾鰭與臀鰭的柔軟部位是鮮黃色的。
This species was observed at Yap (Caroline Islands), in a group of about a dozen individuals living among large (about 1-2 m) rock boulders just above the upper edge of a precipitous drop-off. A juvenile of approximately 4 cm SL was observed at a depth of 120 m, below the site where the type specimens were collected. Its color pattern was consistent with that of the adults (Ref. 59379). Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
在險峻急下降的上緣的正上方生活在大的 (大約 1-2 公尺) 岩石大圓石之中的一群大約十二個個體中, 這種在雅普島 (加羅林群島) 被觀察。 一個大約 4 公分 SL 的稚魚被觀察深度 120 公尺,在模式標本被收集的位置之下。 它的彩色斑紋對成魚的感到一致。 (參考文獻 59379)
