Umwelt: Milieu / Klimazone / Tiefenbereich / Verbreitungsgebiet
Ökologie
seewasser bathydemersal; tiefenbereich 1 - 455 m (Ref. 34024). Deep-water
Northwest Pacific: Japan. Pending a comprehensive study of the group, E. owasianum is restricted to Japan and tentatively refer all of the disjunct southern populations to E. cinereum, the only species name available for the complex.

Geschlechtsreife: Lm ? range ? - ? cm
Max length : 23.6 cm TL Männchen/unbestimmt; (Ref. 5275)
Eel-like, shallow body depth; dorsal fin origin about opposite anal fin origin; males with expanded parapophyses on vertebrae 5 to 18-20; lacking cardiform premaxillary teeth, pelvic fins, swim bladder rocker bone, and ventral tunic ridges on posterior swim bladder (Ref. 34024).
Body shape (shape guide): eel-like.
