Eastern Atlantic: Senegal to Angola, including the western Mediterranean, St. Paul's Rocks (Ref. 13121), and Ascension Island. Reported from Mauritania (Ref. 55783). Western Atlantic: Nova Scotia, Canada to Brazil (Ref. 7251), including the Gulf of Mexico (Ref. 9626) and the Caribbean. Also found in Argentina (Ref. 59355). In the tropical Eastern Pacific, it is replaced by Caranx caballus Günther 1869, which may be conspecific.

Biology     Glossary (e.g. epibenthic)

A schooling species generally not far from the coast (Ref. 5217). Juveniles often found in association with floating Sargassum (Ref. 5217). Adults feed on fishes, shrimps, and other invertebrates. They spawn offshore from January through August (Ref. 26938). Eggs are pelagic (Ref. 4233). Excellent food fish (Ref. 9626); marketed fresh, frozen (Ref. 5521), and salted. Often used for bait (Ref. 26938).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02000 (0.01652 - 0.02422), b=2.96 (2.93 - 2.99), based on LWR estimates for this species (Ref. 93245).
Trophic Level (Ref. 69278):  4.4   ±0.8 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.32-0.38; tmax=11; Fec=41,000).
Vulnerability (Ref. 59153):  Low to moderate vulnerability (34 of 100) .
Price category (Ref. 80766):   Low.
