Short description
Morfologia | Morfometria
Spine dorsali (totale): 0; Raggi dorsali molli (totale): 47-53; Spine anali 2; Raggi anali molli: 12 - 15. This species is distinguished by the following characters: slender elongate and fairly compressed with a high, sail-like first dorsal fin; upper jaw prolonged into a very long beak, slender and round in cross-section; jaws and palatines with villiform teeth; no gill rakers; two dorsal fins, the first very large (42-49 rays) the second small (6-7 rays); pectoral fins 18-20 rays; pelvic fins I, 2 soft rays fused together, very long and narrow, depressible into a groove; caudal peduncle with double keels on each side; body covered with small, embedded scales with 1 or 2 blunt points. Colour of back dark with about 20 bluish vertical bars; belly pale silver; membrane of first dorsal fin blue- black with numerous dark spots; bases of first and second anal fins often tinged with silvery white; remaining fins blackish brown or dark blue (Ref. 43, 26938).
