Etymology: Eptatretus: hepta (Gr.), seven; tretos (Gr.), perforated (i.e., with holes), referring to seven gill apertures on what would later be described as Homea banksii (=E. cirrhatus) [range within genus is 6-14 pairs of gill apertures]. (See ETYFish);  walkeri: In honor of Harold J. Walker, Jr., Collections Manager, Scripps Institution of Oceanography, for help in providing hagfish specimens and data, and for contributions to ichthyology. (See ETYFish).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00204 (0.00092 - 0.00452), b=2.93 (2.73 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  4.2   ±0.7 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (41 of 100).
