Etymology: Nettenchelys: Greek, netta = duck + Greek, enchelys, -yos = eel (Ref. 45335); pygmaea: Named after the Greek pygmaios meaning small, dwarf, referring to the small size of the adults.

Estimates based on models
Preferred temperature (Ref. 115969
): 14.7 - 23.2, mean 18.6 °C (based on 31 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00060 (0.00023 - 0.00155), b=3.08 (2.86 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.3 ±0.4 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 (13 of 100) .
