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

North Atlantic: Nova Scotia and Grand Banks (Canada) to Massachusetts, USA (Ref. 7251). Also known from the Northeast Atlantic and the Mediterranean Sea. Southeast Atlantic and Indian Ocean: South Africa and Australia (including New South Wales). Southwest Pacific: New Zealand. Southern Ocean. Antitropical.

Biology     Glossary (e.g. epibenthic)

An oceanic, epipelagic or mesopelagic species (Ref. 6942). Juveniles occurring in surface waters (Ref. 4542) and associated with pelagic medusas and salps (Ref. 4410), adults found deeper (Ref. 4542). May form small schools. Appears to feed on whatever is available, small fish, squid, large pelagic crustaceans, and other plankton (Ref. 4542).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00661 (0.00345 - 0.01265), b=3.07 (2.89 - 3.25), based on LWR estimates for species & (Sub)Family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.9   ±0.38 se; Based on food items.
Resilience (Ref. 69278):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100) .
Price category (Ref. 80766):   Very high.
