Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 3 - 4; Mjukstrålar i ryggfenan (totalt) : 40 - 45; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 30 - 33. This species is distinguished by its very deep body, almost triangular, extremely compressed; sharp-edged breast; greatest body depth below lateral line at least 4 times greater than greatest body depth above lateral line; anal fin very long-based, commencing at point of insertion of pelvic fins, uniformly very low; dorsal spines (X in juveniles) reducing in number with increasing age. Colour of body with upper sides deep metallic blue, the rest silvery, a row of round to ovoid, dark slaty-blue spots above and below lateral line, sometimes a few additional spots above and below these rows; pelvic fins with a trace of blue, other fins hyaline or slightly dusky (Ref. 47690).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Inhabits deeper coastal waters near the bottom on both the continental shelves and around major island groups; sometimes in river estuaries (Ref. 47690, 48635). Found in schools (Ref. 47690, 48635). Feeds on benthic invertebrates (Ref. 5213). Readily dries in air without salting (Ref. 4375, 48635). Caught in trawls and by beach seine, but mainly by trawling, often incidentally. Marketed fresh and dried (Ref. 47690). Minimum depth from Ref. 30573.
