Eastern Atlantic: occasionally between Azores and Madeira (Ref. 4739), also from Senegal to Gulf of Guinea. Western Atlantic: 30°N-30°S, including the Gulf of Mexico (Ref. 27768). Northwest Atlantic: Canada (Ref. 5951). Indian Ocean: 20°N-20°S. Eastern Pacific: 35°N-35°S. Western Pacific: 30°N-10°S. South China Sea (Ref.74511).

Biology     Glossary (e.g. epibenthic)

An oceanic and mesopelagic species (Ref. 4739, 58302), mainly at 300-650 m (Ref. 4054), 170-500 m at night and 350-600 m during day (Ref. 58302). May make short diel migrations (Ref. 4739). Smaller individuals feed on copepods and ostracods; larger ones feed on euphausiids, salps and chaetognaths (Ref. 4739). Adult complement of photophores acquired at about 14 mm SL (Ref. 4739). Oviparous, with planktonic eggs and larvae (Ref. 35838).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.00732 - 0.05192), b=3.01 (2.78 - 3.24), based on LWR estimates for this Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.1   ±0.19 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (K=0.67).
Vulnerability (Ref. 59153):  Low vulnerability (21 of 100) .
Price category (Ref. 80766):   Unknown.
