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); gomoni: In honor of Martin F. Gomon (b. 1945), Senior Curator, Ichthyology, Museum of Victoria (Melbourne, Australia), for “distinguished” contributions to ichthyology (See ETYFish).
Eponymy: Dr Martin Fellows Gomon (d: 1945) is an US/Australian ichthyologist who first went to Australia to Museum Victoria Melbourne (1979) where he is Senior Curator, Ichthyology. [...] (Ref. 128868), visit book page.

This species differs from all its congeners except four Indo-Pacific species (E. fernholmi, E. indrambaryai, E. okinoseanus and E. wisneri) by having 8 pairs of gill pouches and three-cusp multicusps on the anterior and two-cusp multicusp on
the posterior rows of cusps. It differs from E. fernholmi in number of trunk pores (57-58 vs. 50), tail pores (14-15 vs. 9) and total pores (91-93 vs. 81); from E. indrambaryai in number of total cusps (50 vs. 45-48), trunk pores (57-58 vs. 45-50), tail pores (14-15 vs. 10-13) and total pores (91-93 vs. 77-82); from E. okinoseanus in number of total cusps (50 vs. 40-49), prebranchial pores (12-13 vs. 13-17) and tail pores (14-15 vs. 10-14); from E. wisneri by its number of anterior unicusps (10-11 vs. 9), total cusps (50 vs. 44), prebranchial pores (12-13 vs. 9-10), trunk pores (57-58 vs. 43-45) and total pores (91-93 vs. 73-75) (Ref. 85052).
