Eastern Atlantic: Irish slope to Cape Verde, including the Mediterranean. Occurrence in southern Africa is based only on specimens from off Namibia and not 'west coast of South Africa' as reported by Iwamoto 1986 (Ref. 2800 in FishBase) (Ref. 11953).

Short description पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स
Snout long, narrow, sharply pointed. Dorsal scute row striating from just behind the head and extending to about behind a vertical through the anus, with more than 20 scute. Ventral scute row not reaching anus. Scute keels generally smooth blade-like, without multicuspid tips in small individuals (<30 cm), becoming more multicuspid with size. Scales adherent; belly completely scaled.
Primarily a pelagic feeder, feeds primarily on pelagic copepods, but also takes mysids, shrimps, cephalopods, fish, polychaetes and gastropods (Ref. 1371). Mainly reduced to fishmeal and oil (Ref. 1371).

Estimates based on models
Preferred temperature (Ref. 115969): 4.7 - 13.7, mean 10.4 (based on 141 cells).
Phylogenetic diversity index (Ref. 82804): PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00309 (0.00119 - 0.00804), b=3.12 (2.90 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.6 ±0.3 se; based on diet studies.
लौटाव (Ref. 120179): माध्यम, न्यूनतम जनसंख्या दुगनी होने का समय 1.4 - 4.4 वर्ष। (K=0.22-0.35).
Fishing Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100).
Climate Vulnerability (Ref. 125649): Low vulnerability (13 of 100).
