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.

توصيف مختصر
كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
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).
