Adults are generally found at depths greater than 150 m during the day. Oviparous, with planktonic eggs and larvae (Ref. 35604), which are distributed in the sub-arctic gyre south to about 47°N (Ref. 6848).

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.

Non-Migrant: No. All populations of this species make significant seasonal migrations.

Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Adults are generally found at depths greater than 150 m during the day.

Oviparous (Ref. 35604).
