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); polytrema: poly- (Gr.), many; trema (Gr.), hole, referring to 16 gill apertures per side (See ETYFish).

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven
Copulatory organ absent. The gonads of hagfishes are situated in the peritoneal cavity. The ovary is found in the anterior portion of the gonad, and the testis is found in the posterior part. The animal becomes female if the cranial part of the gonad develops or male if the caudal part undergoes differentiation. If none develops, then the animal becomes sterile. If both anterior and posterior parts develop, then the animal becomes a functional hermaphrodite. However, hermaphroditism being characterised as functional needs to be validated by more reproduction studies (Ref. 51361 ).

Estimates based on models
Preferred temperature (Ref. 123201): 10.5 - 11.8, mean 11.1 °C (based on 8 cells).
Fylogenetische diversiteitsindex (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00211 - 0.00719), b=2.92 (2.74 - 3.10), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trofisch niveau (Ref. 69278): 4.4 ±0.7 se; based on size and trophs of closest relatives
Generation time: 8.9 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.
Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153): High vulnerability (62 of 100).
Nutrients (Ref. 124155): Calcium = 10.4 [2.7, 33.2] mg/100g; Iron = 0.333 [0.119, 0.906] mg/100g; Protein = 2.72 [0.00, 6.54] %; Omega3 = 0.259 [0.101, 0.676] g/100g; Selenium = 13.2 [3.9, 44.3] μg/100g; VitaminA = 9.6 [2.0, 44.9] μg/100g; Zinc = 0.307 [0.153, 0.589] mg/100g (wet weight);
