ກຸ່ມປາທະເລຊະນິດໜຶ່ງທີ່ມີລຳຕົວຍາວຄືອ່ຽນ ແລະບໍ່ມີກະດູກຄາງກະໄຕປາກແຕ່ຈະມີກຸ່ມແຂ້ວເປັນແຜ່ນອ້ອມຮອບປາກ (ຕົວຢ່າງປາ ແຮກຟິດ) (hagfishes) > Myxiniformes (Hagfishes) > Myxinidae (Hagfishes) > Eptatretinae
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.
