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

Atlantic Ocean: widely distributed, including the Mediterranean (Ref. 231). Indo-Pacific. Eastern Pacific: Topanga Beach in southern California, USA to Chile (Ref. 2850).

Biology     Glossary (e.g. epibenthic)

Oceanic and can live at great depths (Ref. 2850), but occasionally cast up on beaches (Ref. 9563). Feed on euphausiid crustaceans, small fishes and squid (Ref. 6738). Spawning occurs between July and December and larvae are encountered near the surface (Ref. 9337). Also caught with encircling nets and marketed fresh (Ref. 9337). In Guinness Book of Records as longest bony fish (Ref. 6472).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.6875   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (-0.30300 - 0.32300), b=3.04 (2.92 - 3.16), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.2   ±0.40 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Assuming tm>10).
Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100) .
Price category (Ref. 80766):   High.
