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).

Descrição breve Morfologia | Morfometria

Espinhos dorsais (total): 0; Raios dorsais moles (total): 0; Espinhos anais 0; Raios anais moles: 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).

Biologia     Glossário (ex. epibenthic)

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.

Life cycle and mating behavior Maturidade | Reprodução | Desova | Ovos | Fecundidade | Larvas

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.
