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);  alastairi: In honor of Alastair Graham (b. 1964), Fish Collection Manager, CSIRO (Commonwealth Scientific and Industrial Research Organisation), Canberra, Australia, for help and hospitality offered to second author.

Korte beschrijving Morfologie | Morfometrie

This species differs from all its congeners except for the western Atlantic species (E. mendozai, E. minor and E. multidens) by possessing 6 pairs of gill pouches and three-cusp multicusps on the anterior and posterior rows of cusps. It differs from E. mendozai in number of total cusps (48-56 vs. 56-61), trunk pores (50-55 vs. 48-48) and total pores (83-88 vs. 77-82; from E. minor in number of prebranchial pores (13-16 vs. 15-18), trunk pores (50-55 vs. 41-48) and total pores (83-88 vs. 74-82); and from E. multidens by its number of tail pores (11-13 vs. 15-16) and total pores (83-88 vs. 88-93) (Ref. 85052).
