Actinopterygii (ray-finned fishes) > Osmeriformes
(Smelts) > Bathylagidae
Etymology: schmidti: Named after P.J. Schmidt, USSR ichthyologist (Ref. 6885).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathypelagic; depth range 394 - 1800 m (Ref. 6793). Deep-water; 61°N -
North Pacific: southeastern Hokkaido, Japan to Navarin Canyon in the Bering Sea and southern British Columbia, Canada. Possibly in Kamchatka (Ref. 6885). Regarded as a subspecies of Leuroglossus stilbius, Gilbert 1890 but Peden (1981) presented evidence for separating the two and Dunn (1983) placed them in the genus Leuroglossus.
