Atlantic,Mediterranean, Indian and Pacific (Western Central). Eastern Pacific population recognized as subspecies Auxis thazard brachydorax (Ref. 32349). Many authors have used the name Auxis thazard as including Auxis rochei in the belief that there was only a single worldwide species of Auxis. Highly migratory species.

Short description Morfologi | Morfometri

Taggstrålar i ryggfenan (totalt): 10 - 12; Mjukstrålar i ryggfenan (totalt): 10-13; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 10 - 14. This species is distinguished by the following characters: a robust body, elongated and rounded; teeth small and conical, in a single series; total gill rakers on first gill arch 36-42; dorsal fins 2, D1 X-XII, separated from the second by a large interspace (at least equal to length of first dorsal-fin base), second dorsal fin followed by 8 finlets; anal fin followed by 7 finlets; pectoral fins short, but reaching past vertical line from anterior margin of scaleless area above corselet; a large single-pointed flap (interpelvic process) between pelvic fins; body naked except for the corselet, which is well developed and narrow in its posterior part (no more than 5 scales wide under second dorsal-fin origin); a strong central keel on each side of caudal-fin base between 2 smaller keels. Colour of back bluish, turning to deep purple or almost black on the head; a pattern of 15 or more narrow, oblique to nearly horizontal, dark wavy lines in scaleless area above lateral line; belly white; pectoral and pelvic fins purple, inner sides black (Ref 9684).

Biologi     Ordlista (t.ex. epibenthic)

Adults are epipelagic in neritic and oceanic waters (Ref. 9340). They feed on small fish, squids, planktonic crustaceans (megalops), and stomatopod larvae (Ref. 5213). Because of their abundance, they are considered an important element of the food web, particularly as forage for other species of commercial interest. They are preyed upon by larger fishes, including other tunas (Ref. 9987). Marketed fresh and frozen (Ref. 9340) and also utilized dried or salted, smoked and canned (Ref. 9987).

In correlation with temperature and other environmental changes, the spawning season varies with areas, but in some places it may even extend throughout the year.
