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); moki: In honor of Hin-kiu Mok (b. 1947), National Sun Yat-Sen University, Taiwan, for his many “outstanding” contributions to hagfish knowledge (See ETYFish).
Eponymy: Dr Michael Hin-Kiu Mok (d: 1947) is a Taiwanese marine biologist and ichthyologist who is a Research Associate, Vertebrate Zoology, Ichthyology, AMNH and after his retirement has become an Adjunct Professor, Department of Oceanography, National [...] (Ref. 128868), visit book page.
