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..

Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 2.5 cm SL male/unsexed; (Ref. 48637)
(total): 6 - 7;
soft rays: 8 - 9. This species is distinguished by the following characters: cephalic sensory-canal pore system without the NA, PITO & IT pores; dorsal/anal-fin formula 9/8; the fifth pelvic-fin ray 50-80% of the fourth ray; unbranched pectoral rays; caudal fin base with pale-edged black spot (Ref. 107299).
Often seen resting on live coral (Ref. 11441, 48637) of lagoon reefs at depths of 1 to over 6 m (Ref. 37816). Often in small groups (Ref 90102). Nektonic (Ref. 75154).
