Mixini (Missine) (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); multidens: multus (L.), many; dens (L.), tooth, referring to high tooth count (three fused teeth in each row). (See ETYFish).

Minimum depth given from Ref. 52140.

Life cycle and mating behavior Maturities | Riproduzione | Spawnings | Egg(s) | Fecundities | Larve

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. 115969): 8.6 - 15.5, mean 11.5 (based on 79 cells).

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): 4.3 ±0.7 se; based on size and trophs of closest relatives

Resilienza (Ref. 120179): Basso, tempo minimo di raddoppiamento della popolazione 4.5 - 14 anni (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (53 of 100).
