Teleostei (teleosts) > Gobiiformes (Gobies) > 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; specca: Name based on the Anglo/Saxon 'specca' for speckled, referring to the heavy speckling of chromatophores over the body; noun in apposition.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8; Vertebrae: 26. This species is distinguished from its congeners by the following set of characters: cephalic sensory pore system pattern 1 (complete); 8/8 dorsal/anal-fin formula; body heavily sprinkled with chromatophores; upper pectoral-fin base pigmented; 4 subcutaneous body bars between anal-fin origin and caudal-fin base; occipital spot absent; pale opercular membrane; first dorsal fin sprinkled with small melanophores and chromatophores; caudal peduncle with no distinct dark spot or bar; cheek crossed by dark lines, red spots absent (Ref. 95167).

Estimates based on models

Preferred temperature (Ref. 123201): 20.5 - 26.3, mean 23.3 °C (based on 102 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 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): 2.9 ±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).
