Oligoplites saurus in El Salvador
Leatherjack

Oligoplites saurus (Bloch & Schneider, 1801)
Family:	Carangidae (Jacks and pompanos)	picture (Olsau_j0.jpg) by Sazima, I.
Order:	Perciformes (perch-likes)
Class:	Actinopterygii (ray-finned fishes)
FishBase name:	Leatherjack
Max. size:	35.0 cm TL (male/unsexed; Ref. 5217); max. published weight: 287 g (Ref. 3277)
Environment:	reef-associated
Climate:	subtropical; 45°N - 35°S
Global Importance:	fisheries: minor commercial; bait: occasionally
Resilience:	High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.)
Distribution:	Western Atlantic: Maine, USA and northern Gulf of Mexico to Uruguay; throughout most of the West Indies (Ref. 3277). Absent from the Bahamas (Ref. 26938). Eastern Pacific: Baja California, Mexico to Ecuador (Ref. 9283). Two subspecies exists (Ref. 3277): Oligoplites saurus saurus (western Atlantic population) and Oligoplites saurus inornatus (eastern Pacific population).
Diagnosis:	Dorsal spines (total): 5-6; Dorsal soft rays (total): 19-21; Anal spines: 2-3; Anal soft rays: 18-21. Body elongate and strongly compressed (depth from 3.5 to 4.4 times in standard length); posterior end of upper jaw reaching posterior rim of eye; upper jaw teeth small and villiform; lower branch of first gill arch with 14 to 18 gill rakers; scales small but visible, needle-shaped, embedded in the skin; back blue green; flanks and belly silvery to white, sometimes with yellow or golden highlights; pectoral and caudal fins yellowish (Ref. 55763); Dorsal fin has 5 nearly separate spines.
Biology:	Found inshore, usually along sandy beaches, in bays and inlets (Ref. 9283). Enters estuaries and fresh water (Ref. 9283). Prefers turbid water (Ref. 9283). Occurs in schools, usually large and fast moving, often leaping out of the water (Ref. 9283). Juveniles may float at the surface with tail bent and head down. Feeds on fishes and crustaceans (Ref. 9283). Its dorsal and anal spines are connected to venomous glands that can inflict painful wounds (Ref. 9283). Venom glands were not visible, not able to be confirmed in specimen (Ref. 57406). Current information in the table (dangerous fish) do not match; needs verification. Juveniles have incisor-like outer teeth and serve as cleaners for other fish; as fish grow, their teeth become conical and their diet changes (Ref. 26938). Marketed fresh and salted or dried but the flesh is not highly esteemed (Ref. 9283)
Threatened:	Not Evaluated, see IUCN Red List , (Ref. 36508)
Dangerous:	venomous , Smith-Vaniz, W.F.. 1995
