Eastern Atlantic: Canary Islands to Angola but not recorded from the Gulf of Guinea; between 45°N and 50°N, and off South Africa. Also known from the Northwest Pacific. Leptostomias gracilis, Leptostomias macropogon, Leptostomias longibarba, Leptostomias bermudensis, Leptostomias analis and Leptostomias leptobolus are probably synonyms of a single species (the entire complex needs a thorough study, Ref. 4468).

Estimates based on models

Preferred temperature (Ref. 123201): 24.1 - 28.2, mean 27 °C (based on 250 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00117 - 0.00783), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).
