Actinopterygii 辐鳍鱼纲 (条鳍鱼) > Perciformes (Perch-likes) > Gobiidae (Gobies) > Gobiinae
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.

简单描述 型态特徵 | 形态测量图

背棘 (总数): 7; 背的软条 (总数): 8-10; 臀棘 1; 臀鳍软条: 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).
有别于 E. storthynx 藉着缺少眼睛后面的斑点, 而且从 E. zebrina 在尾鳍基底的上、下部分上藉着具有深色的斑点取代一个中央的深色斑点。

生物学特性     字汇 (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 天的此鱼种生命在最, 藉由在开放性海域中度过三个星期的仔鱼而且在一个礁上定居在二个星期里面成熟, 只是离开成鱼 (那是 1 到 2个公分长的) 三个星期繁殖。 这一个策略 '生活快速地, 死幼鱼' 策略被感觉是对密集掠食的一个回应。 从卷标-取回的数据每日的死亡率可能是与 8% 一样高。 (参考文献 54199) 生存在深度小于 4 在舄湖礁的砂质底部上到 17 与 21 公尺之间.(参考文献 1602,37816,48637)
