Etymology: Nettenchelys: Greek, netta = duck + Greek, enchelys, -yos = eel (Ref. 45335); exoria: From the Greek exorios meaning beyond the frontier, in reference to the posterior nostrils, which have migrated beyond the occiput and are located behind the head (Ref. 40819).

Estimates based on models
Preferred temperature (Ref.
123201): 10 - 17.5, mean 13.1 °C (based on 28 cells).
Índice de diversidade filogenética (Ref.
82804): PD
50 = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00089 (0.00036 - 0.00223), b=2.98 (2.77 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Nível Trófico (Ref.
69278): 3.4 ±0.5 se; based on size and trophs of closest relatives
Resiliência (Ref.
120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Assuming tmax>10).
Fishing Vulnerability (Ref.
