Biology: |
This species was observed and collected in association with the Sakura shrimp, Lucensosergia lucens (Hansen, 1922) in Taiwan during fishing season (December-May) in mid-water trawls, together with Parascombrops yamanouei and other pelagic fishes like bregmacerotids and surface-migrating myctophids. In the Arafura Sea, it was collected in association with demersal fishes like Acropoma japonicum Günther, 1859, Malakichthys levis Yamanoue & Matsuura, 2001, Owstonia aff. Pectinifer (Myers, 1939) and Bembrops spp. at depth close to sea bottom but not far from a major drop-off. (Ref. 116586). |
