Short description आकृति विज्ञान | मौरफोमैटरिक्स

This species differs from all its congeners except five Pacific species (Eptatretus carlhubbsi, Eptatretus cirrhatus, Eptatretus goliath, Eptatretus laurahubbsae, Eptatretus strahani) and two Atlantic Ocean species (Eptatretus caribbeaus, Eptatretus menezesi) by having 7 pairs of gill pouches and three-cusp multicusps on the anterior and posterior rows of cusps. It further differs from these congeners by having the following characters: 10 posterior unicusps (vs. 11-13 in E. carlhubbsi, 7-9 in E. cirrhatus, 11-16 in E. laurahubbsae); 52 total cusps (vs. 54-58 in E. caribbeaus, 61-71 in E. carlhubbsi, 61-68 in E. laurahubbsae); 18-19 prebranchial pores (vs. 13-15 in E. caribbeaus, 12-17 in E. carlhubbsi, 14-15 in E. goliath, 14-17 in E. laurahubbsae, 13-17 in E. menezesi, 13-16 in E. strahani); 5 branchial pores (vs. 6-7 or 6-8 for remaining seven-gilled species); 48-49 trunk pores (vs. 60-70 in E. carlhubbsi, 57-58 in E. goliath, 60-67 in E. laurahubbsae); 83-84 total pores (vs. 93-110 in E. carlhubbsi, 92 in E. goliath, 97-105 in E. laurahubbsae, 86-94 in E. menezesi). In addition, these congeners, except E. caribbeaus, have two bilaterally symmetrical nasal-sinus papillae in the dorsal surface of the nasal sinus, while it is absent in E. astrolabium (Ref. 85154).
