Classification / Names Common names | Synonyms | Catalog of Fishes (gen., sp.) | ITIS | CoL | WoRMS | Cloffa

Myxini (hagfishes) > Myxiniformes (Hagfishes) > Myxinidae (Hagfishes) > Eptatretinae
Etymology: Eptatretus: Greek, epta = seven + Greek, tretos, -e, -on = with holes (Ref. 45335);  strickrotti: Named in honor of DSV Alvin pilot Mr. Bruce Strickrott, in recognition of his expertise with Alvin and slurp-gun capture of the holotype specimen and other mobile hydrothermal vent animals.

Environment / Climate / Range Ecology

Marine; bathydemersal; depth range 2100 - 2300 m (Ref. 74406).   Deep-water, preferred ?; 37°S - 38°S, 111°W - 110°W (Ref. 74406)

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

South eastern Pacific: East Pacific Rise vent site. Possible wider distribution 30° northward and depth range down to 2900m if the individuals filmed at Grommit, Oasis, and Yaquina vent sites are the same species.

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 31.4 cm male/unsexed; (Ref. 74406)

Short description Morphology | Morphometrics

Slender body than other species, depth 2.9% TL (at pharyngocutaneous duct); paired and median ventral nasal sinus papillae both present, and 10 afferent branchial arteries on the medial ventral aorta; slime pores: 18 prebranchial, 12 branchial, 70 trunk, 19 caudal, total 119; 12 gill pouches and apertures; pharyngocutaneous duct widely separated from the opening of posterior left gill apertures; 3 multicusps in anterior row and 2 in posterior row, total cusps 46; paired dorsal nasal sinus papillae; eyespot absent; body coloration pink.

Biology     Glossary (e.g. epibenthic)

First record of a myxine record in a hydrothermal vent. Fourth record of a myxine species below 2000m (Ref. 74406). Known from one specimen only, the holotype (in 2007). Possibly, individuals filmed at Grommit, Oasis, and Yaquina vent sites pertain to the same species (Ref. 74406).
