Etymology: Evermannichthys: From Evermann, 1902, researcher about fauna + greek, ichthys = fish (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 27 - 30 m (Ref. 40966). Tropical
Western Central Atlantic: known from the type locality, Navassa Island. Also from the Bahamas (Ref. 92840).

Maturity: Lm ?  range ? - ? cm
Max length : 3.0 cm SL male/unsexed; (Ref. 92840)
Morphology | Morphometrics
(total): 6 - 7;
soft rays: 9. Distinguished by having the following characteristics: thin and elongate in form; reduced scale cover and head pores; depth of body about 2 mm (Ref. 92840); uniformly dark on dorsal third of body and pale on remainder; clear median and paired fins; frenum connecting the upper lip to snout is reduced; separated upper lip and snout; tongue is emarginate (Ref. 44822).
Obligate sponge dwellers. Live deep within canals of the sponges, near the openings to the incurrent canals. Sponges provide species with protection from predators and an available food source in many invertebrates. Eggs found within sponge or small plankton brought through incurrent pores (Ref. 92840).

Estimates based on models
Preferred temperature (Ref. 115969
): 21.2 - 27.7, mean 26.5 °C (based on 42 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00603 (0.00271 - 0.01339), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.1 ±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.).
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
