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..
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range - 150 m (Ref. 86942), usually - m (Ref. ). Tropical; 0°C -
Western Pacific: definitely known from Indonesia. Occurrence in Australia, the Philippines, Palau, and Japan (and other countries not mentioned) need further confirmation through genetic data..
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 3.0 cm SL male/unsexed; (Ref. 48637)
(total): 6 - 7;
soft rays: 8. This species is distinguished from its congeners by the following set of characters: cephalic
sensory-pore system pattern IV of Lachner & Karnella (1983); i.e. the PITO and IT pores are lacking and the AITO pore is enlarged); dorsal/anal-fin formula 9/8, unbranched pectoral-fin rays; genital papilla of male non-fimbriate; usually pectoral-fin base with a few chromatophores restricted to an area across from the top few fin rays, but more pigmentation on the rest of the base can be present; when preserved ventral half of body with a slightly dusky stripe, wider than eye diameter at middle of anal fin, with a dark semi-circular spot at the caudal-fin base. When alive: ventral
half of body red with a narrow white line above it running the length of the body; eye with a narrow white line running across it above the pupil, a short white line behind the eye, and a small white spot under the eye (Ref. 95677).
Lives among branching and encrusting corals (Ref. 9210) in lagoon reefs at depths of 10 or more (Ref. 37816, 48637). Forms groups among branches of Acropora coral (Ref 90102).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00332 - 0.01511), b=3.08 (2.90 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
