Circumglobal: In tropical to subtropical waters; except the eastern Pacific (Ref. 33390). Eastern Atlantic: Portugal to South Africa, including the Mediterranean and Black Sea, Madeira, and the Canary Islands. Western Atlantic: Canada and Bermuda to Argentina (Ref. 7251). Indian Ocean: along the coast of East Africa, Madagascar, southern Oman, southwest India, the Malay Peninsula, and Western Australia (Ref. 11441). Southwest Pacific: Australia except the Northern Territory, and New Zealand (Ref. 11441). Absent from eastern Pacific and northwest Pacific. Barely entering the Western Central Pacific region. Records from the Northern Territory, Australia and from Indonesia appear to be erroneous (Ref. 9860). Occurrence in Taiwan (Ref. 5193) and Hawaii (Ref. 4517) need verification.

Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 8 - 9; Radios blandos dorsales (total) : 23 - 28; Espinas anales: 2 - 3; Radios blandos anales: 23 - 27. Jaw teeth prominent, sharp, compressed, in a single series. Two dorsal fins, the first short and low, with 7 or 8 feeble spines connected by a membrane. Back greenish, sides and belly silvery (Ref. 9860).

Occur in oceanic and coastal waters (Ref. 26340). They are most common along surf beaches and rock headlands in clean, high energy waters, although adults can also be found in estuaries and into brackish water (Ref. 6492). Small fish may be found in shallow coastal waters at least 2 m depth (Ref. 9563), in schools pursuing and attacking small fishes (Ref. 9626). Adults are in loose groups, often attacking shoals of mullets or other fishes and destroying numbers apparently far in excess of feeding requirements (Ref. 9860). Feed on other fish (Ref. 5377), crustaceans and cephalopods (Ref. 47377). Associated with sharks and billfishes (Ref. 26340). Voracious and aggressive (Ref. 9626), reported to bite when handled. Migrate to warmer water during winter and to cooler water in summer (Ref. 9987). Popular game fish (Ref. 6638). Good food fish; marketed mostly fresh (Ref. 9860), but also dried or salted (Ref. 5284), and frozen (Ref. 9987).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Fecundity varies from 400,000 to 2,000,000 eggs depending on the size of the individual (ranging from 370,000 in a 31 cm fish to 1,240,000 in a 54 cm fish) (Ref. 27695). Tailor are serial spawners (Ref. 6390).
