Description
Size: Maximum about 3.2 m (total length); common to 2.7 m (total length).

Max. weight reported: 100.2 kg

Color: Back dark with about 20 bluish vertical bars; belly pale silver; membrane of first dorsal fin blue black with numerous dark spots.

Body elongate, strongly compressed, the upper jaw greatly produced. Head 2.9-3.2 in standard length, 3.5-3.8 in total length. Dorsal profile of head gradually ascending to dorsal. Rostrum about 4.5 in total length. Granulations on lower part of rostrum stronger than those on sides. Lower jaw with small teeth. Dorsal fin origin on nape; first dorsal remarkably high and sail-like, anterior rays markedly shorter than middle rays; posterior rays decreasing rapidly in length. Longest dorsal ray 2.0-2.5 times depth of body. First anal below posterior quarter of first dorsal; second anal opposite to second dorsal. Pectoral falciform, as long as half length of head. Ventral fin equal to or longer than pectoral and depressible in a groove of the abdomen. First anal lobe equal to postorbital length of head.
Number of spines in the first dorsal fin: XLII-XLVIII; number of spines and rays in the second dorsal fin: 7; number of spines and rays in the first anal fin: 10-12; number of spines and rays in the second anal fin: 7; number of rays in the pectoral fin: 17-18; number of spines and rays in the ventral fin: I, 2. Feeds mainly on fishes, crustaceans and cephalopods.

Dioecious, external fertilization, nonguarders, open water/substratum egg scatterers. Spawning occurs with males and females swimming in pairs or with two or three males chasing a single female (probably a mating behavior). The ripe ovarian eggs are about 0.85 mm in diameter and have a single oil globule; there are no structures on the vitalize membrane and the egg is transparent. Eggs shed from captured female in the Indian Ocean averaged 1.304 mm in diameter. Most likely schools by size.

Max. age reported: 13 years
