Etymology: Eustomias: Greek, eu = good + Greek, stoma = mouth (Ref. 45335); monoclonoides: Named for the similarity of its bulb shape and pigmentation to those of monoclonus.
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range ? - 4500 m (Ref. 34246). Deep-water
Eastern Central Atlantic: known only from the extreme eastern equatorial Atlantic.

Morphology | Morphometrics
The barbel has its single branch arising from the stem at 70-75% BL; the branch almost reaching the barbel tip, with small side filaments proximally and has a prominent bulblet and longer side filaments at 50-75% of branch length, ending with small filaments off bulblet. Terminal filament length 9-16% of distal barbel, nearly reaching barbel tip (Ref. 34246).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.8 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (22 of 100) .
