Myxini (slijmprikken) (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); stoutii: In honor of Arthur B. Stout (1814-1898), surgeon and corresponding secretary of the California Academy of Sciences [see box, below]. (See ETYFish).

Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 0; Dorsale zachte stralen (totaal) : 0; Anale stekels: 0; Anale zachte stralen: 0. No true fins - one dorsal finfold, far back, median, very low, continuous with caudal; caudal broad, rounded; ventral finfold very low, origin somewhat posterior to last gill pore, extending to anus (Ref. 6885). Dark brown, tan, gray, or brownish red, often tinted with blue or purple, never black, lighter ventrally, rarely with large patches of white; preserved specimens light brown (Ref. 6885).

Inhabits fine silt and clay bottoms (Ref. 6885). Enters large fishes by way of the mouth and anus and feed on its viscera and muscles (Ref. 6885). May greatly diminish catches taken with fixed gears (Ref. 6885). Produces mucilaginous slime when harassed (Ref. 6885). Probably exhibits hermaphroditism (Ref. 56947). Due to its primitive metabolism it is collected for research purposes (Ref. 6885). TBK: demerspelag.

Levenscyclus en paargedrag Maturities | Voortplanting | Spawnings | Egg(s) | Fecundities | Larven

Copulatory organ absent (Ref. 51361). Presence of bisexual juvenile gonad, requires further investigation regarding hermaphroditism (Ref. 56947). In one study (Ref. 40710), hermaphroditism is exhibited by only 0.2% of the individuals studied.

Estimates based on models

Preferred temperature (Ref. 115969): 5.8 - 9.4, mean 7.1 (based on 54 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00288 (0.00170 - 0.00489), b=2.88 (2.73 - 3.03), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 4.2 ±0.70 se; based on food items.

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec = 28).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (45 of 100).
