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).
Eponymy: Harold J Walker Jr is a Senior Museum Scientist and Collections Manager at Scripps Institution of Oceanography, University of California, San Diego. [...] (Ref. 128868), visit book page.

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00204 (0.00094 - 0.00444), b=2.93 (2.74 - 3.12), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisk nivå (Ref. 69278): 4.2 ±0.7 se; based on size and trophs of closest relatives
