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); fudgei: Named for Professor Douglas S. Fudge, for his many contributions to the knowledge of the physiology, biomechanics and biomimetics of hagfishes and hagfish slime.

Short description
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
This species is distinguished from all iits congeners, except astrolabium, carlhubbsi, caribbeaus, cirrhatus, cryptus, goliath, goslinei, laurahubbsae, menezesi, strahani by
having seven pairs of gill apertures well-spaced and arranged in a near straight line; differs from all these seven-gilled congeners by having a 3/2 multicusp pattern of teeth (vs. a 3/3 or 2/3 multicusp pattern), with 10-11 anterior unicusps (vs. 15-17 in carlhubbsi. and 13-17 in laurahubbsae, 50-51 total cusps (vs. 63-71 in carlhubbsi, 54-58 in caribbeaus, 61-68 in laurahubbsae, 5-60 in menezesi), prebranchial 12-14 pores (vs. 18-19 in astrolabium, 15-18 in cirrhatus), trunk pores 48-52 (vs. 60-70 carlhubbsi, 56-60 in goliath, 37-43 in goslinei, 60-67 in laurahubbsae) and total pores 79-84 (vs. 93-110 in carlhubbsi, 89-95 in goliath, 65-72 in goslinei, 97-105 in laurahubbsae); further differs from most
seven-gilled congeners by having no nasal-sinus papillae (vs. two bilaterally symmetrical nasal-sinus papillae in carlhubbsi, cirrhatus, cryptus, goliath, goslinei, laurahubbsae, menezesi. Strahani) (Ref, 128403).
From collection data, the bottom was covered by coral and sand (Ref. 128403).
