Myxini (hagfishes) (hagfishes) > Myxiniformes (Hagfishes) > Myxinidae (Hagfishes) > Eptatretinae
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); goliath: The giant slain by David in the biblical book of Samuel, now a synonym for “giant”; at 1275 mm TL and 6.2 kg, the largest known hagfish. (See ETYFish).

Diagnosis: Distinguished from its congeners by the unique combination of the following characters: 7 pairs of gill pouches; 3-cusp multicusps in anterior and posterior rows; 11-13 unicusps in anterior rows; 9 unicusps in posterior rows; 54 total cusps; 14-15 prebranchial pores; 57-58 trunk pores; 13-14 tail pores; 92 total pores; ventral finfold prominent (Ref. 57440).

Adult female holotype had dozens of small eggs, 45 X 14 mm, in the mesentery, which was attached to the body wall. The eggs did not have terminal anchor filaments and hooks (Ref. 57440).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00204 (0.00092 - 0.00452), b=2.93 (2.73 - 3.13), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.8 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): Rendah, Waktu penggandaan populasi minimum 4.5 - 14 tahun (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (77 of 100).
