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.
Environment: milieu / climate zone / depth range / distribution range
; 海 関連する礁; 深さの範囲 3 - 20 m (Ref. 90102). Tropical
Indo-West Pacific: Seychelles to Indonesia, north to Japan (Ogasawara Islands); east to Micronesia and Melanesia to Wallis and Futuna; south to Australia (Western Australia and Great Barrier Reef). The species in Fiji and Tonga is considered E. cf. sigillata.
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm 1.0, range 1 - 2 cm
Max length : 3.0 cm SL オス/雌雄の選別がない; (Ref. 48637); 最大記録サイズ: 0.16 年 (Ref. 58013)
背面の脊椎 (合計): 7; 背鰭 (合計): 8-10; 肛門の骨 1; 臀鰭: 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).
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).
