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; fallax: Name from Latin word 'fallax' meaning deceitful, false; refers to its superficial similarity to Eviota natalis; noun in apposition.

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 1; Anal soft rays: 8. This species is distinguished from its congeners by the following characters: dark occipital spot, more well-developed in males and in preservation; an orange spot behind the eye in life; cephalic sensory-pore system pattern Group I (complete); dorsal/anal formula often 9/8; eye diameter 26.7-34.4% HL; caudal-peduncle depth 10.9-12.4% SL; 4th pelvic-fin ray with short, thick branches bound together by membranes (Ref. 79588).

Inhabits rocky caverns or coral heads on sand seen most frequently at depths of about 8-15 m on either live coral (frequently faviids) or on rocky surfaces covered with coralline algae patches (Ref. 79588).

Estimates based on models

Preferred temperature (Ref. 123201): 26.7 - 29.2, mean 28.7 °C (based on 662 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.0 ±0.3 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
