Etymology: Myxine: Ancient Greek word for a slimy fish: myxa, slime; -inus, one who, referring to copious amounts of slime produced by M. glutinosa. (See ETYFish);  mcmillanae: In honor of marine biologist Charmion B. McMillan (b. 1925), Scripps Institution of Oceanography, for her “fine” contributions to hagfish science. (See ETYFish).

Biologia     Glossário (p.ex. epibenthic)

Found burrowing in mud in very deep water (Ref. 26938).

Ciclo de vida ou comportamento de acasalamento Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

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): 3.9 - 7, mean 5.5 °C (based on 93 cells).
Índice de diversidade filogenética (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00115 (0.00045 - 0.00296), b=3.03 (2.80 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  3.4   ±0.6 se; based on size and trophs of closest relatives
Resiliência (Ref. 120179):  Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Moderate vulnerability (37 of 100).
