Etymology: Eviota: No etymology given, suggested by Christopher Scharpt: from Latin 'eu' for 'true' and 'iota' for anything very small, in combination 'truly very small' referring to it as being the smallest vertebrate at the time it has benn described by Jenkins (thus, making the suggestion by Scharpt plausible..  More on authors: Jewett & Lachner.

簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 7; 背的軟條 (總數): 8-10; 臀棘 1; 臀鰭軟條: 7 - 8. Characterized by semi-translucent body with irregular, internal reddish midlateral stripe; white stripe along spinal column interrupted by reddish bars that extend ventrally; row of small reddish spots along dorsal midline; usually with narrow reddish bars above anal fin; often prolonged and filamentous first four dorsal spines of male and first three of female; unbranched pectoral rays; longitudinal scale series 21-24; ctenoid scales, absent on head , nape and pectoral fin base; depth of body 4.3-5.0 in SL (Ref. 90102).
有別於 E. storthynx 藉著缺少眼睛後面的斑點, 而且從 E. zebrina 在尾鰭基底的上、下部分上藉著具有深色的斑點取代一個中央的深色斑點。

生物學特性     字彙 (例如 epibenthic)

Adults live for 59 days at the most, with larvae spending three weeks in the open ocean and maturing within two weeks of settling on a reef, leaving the adults (which are 1 to 2 centimeters long) just three weeks to reproduce. This strategy of 'live fast, die young' is perceived to be a response to intense predation. Daily mortality rate, from tag-recapture data, might be as high as 8% (Ref. 54199). Occur at depths less than 4 to between 17 and 21 m on sandy bottoms of lagoon reefs (Ref. 1602, 37816, 48637). Minimum depth from Ref. 58018. Spawning appears to be repeated on a regular cycle, semilunar or every 14 days (Ref. 116739).

59 天的此魚種生命在最, 藉由在開放性海域中度過三個星期的仔魚而且在一個礁上定居在二個星期裡面成熟, 只是離開成魚 (那是 1 到 2個公分長的) 三個星期繁殖。 這一個策略 '生活快速地, 骰子幼魚' 策略被感覺是對密集掠食的一個回應。 從標籤-取回的資料每日的死亡率可能是與 8% 一樣高。 (參考文獻 54199) 生存在深度小於 4 在潟湖礁的砂質底部上到 17 與 21 公尺之間.(參考文獻 1602,37816)
