Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

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.

Biology     Glossary (e.g. epibenthic)

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).

Estimates based on models

Preferred temperature (Ref. 123201): 2 - 4.7, mean 3.1 °C (based on 151 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00617 (0.00318 - 0.01197), b=2.95 (2.78 - 3.12), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.0 se; based on diet studies.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (14 of 100).
