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); cheni: In honor of vertebrate zoologist Jianshen (“Johnson”) T. F. Chen (1898-1988), Director, National Taiwan Museum (Taipei), for “important” contributions to the taxonomy of Taiwanese fishes. (See ETYFish).

Descrição suscinta Chaves de identificação | Morfologia | Morfometria

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. 115969): 2.8 - 6.4, mean 4.2 (based on 63 cells).

Índice de diversidade filogenética (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).

Nível Trófico (Ref. 69278): 4.1 ±0.7 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): Low to moderate vulnerability (28 of 100).
