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.

Estimates based on models
Preferred temperature (Ref.
123201): 24.7 - 29.3, mean 28.2 °C (based on 2315 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00692 (0.00284 - 0.01683), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.0 ±0.3 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.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
Nutrients (Ref.
124155): Calcium = 534 [216, 1,997] mg/100g; Iron = 1.97 [0.76, 4.78] mg/100g; Protein = 17.5 [15.3, 19.5] %; Omega3 = 0.102 [0.029, 0.360] g/100g; Selenium = 37.2 [8.8, 132.2] μg/100g; VitaminA = 101 [16, 587] μg/100g; Zinc = 5.63 [2.78, 10.07] mg/100g (wet weight);
