Etymology: Leptostomias: Greek, leptos = thin + Greek, stoma = mouth (Ref. 45335). More on author: Regan, Trewavas.
Environment: milieu / climate zone / depth range / distribution range
Marine; pelagic-oceanic. Subtropical; 30°N - 34°S
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).

Maturity: Lm ?  range ? - ? cm
Max length : 38.0 cm SL male/unsexed; (Ref. 4468)
Needs further study.

Estimates of some properties based on models
Preferred temperature (Ref. 115969
): 24.1 - 28.2, mean 27 (based on 250 cells).
Phylogenetic diversity index (Ref. 82805
= 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.5 ±0.80 se; Based on food items.
Resilience (Ref. 69278
