Ecologia
marino batidemersale; distribuzione batimetrica 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.

Breve descrizione
Chiavi di identificazione | Morfologia | Morfometria
