Biologi     Ordlista (t.ex. epibenthic)

Rare species (Ref. 34024). This species ventures out for about 800 km from the continental break and occurs primarily between 1800 and 3300 m but two specimens were caught in very shallow water at 245 m or near the surface. The reason for the unusual shallow catches are not known (Ref. 125143). Reproductive strategy possibly similar to other members of this family featuring oviparity, with oval pelagic eggs floating in a gelatinous mass (Ref. 205).
