Description
Size: Maximum 150 cm; common to 105 cm

Color: Grey/brown on back shading to silvery grey on flanks and belly; fins reddish; a black spot at pectoral fin base.

A large, fairly elongate species (body depth rarely less than 3 times in standard length), with a big terminal mouth, the jaws meeting evenly in front, or the lower jaw slightly longer, teeth in both jaws differentiated into large and small; the large ones not canine-like, forming the outer series in upper jaw, and the inner series in lower; only the large teeth are visible in big specimens; rostral pores 5, the outer pair minute or obsolete in larger specimens; marginal pores 5; mental pores in 3 pairs, the first small and round, at front of chin, the others as small slits; sagitta (large earstone) with a tadpole-shaped impression, the "tail" of which is J-shaped; gillrakers rather slender, 8 to 10 on lower limb of first arch. Dorsal fin with 10 spines, followed by a notch, second part of fin with 1 spine and 26 to 29 soft rays; pectoral fins short, 19 to 21% of standard length or 1 ½ times in head length; anal fin with 2 spines and 7 soft rays, the second spine weak and about 1/2 the length of the longest soft fin ray; caudal fin almost truncate, or with upper corner pointed and the lower one rounded. Scales cycloid (smooth) on snout and below eyes, elsewhere ctenoid (rough to touch); pectoral fin axil scaleless; lateral line scales reaching to tip of caudal fin. Swimbladder carrot-shaped, with 25 to 35 pairs of arborescent appendages of approximately equal size, branching in a rather ragged-looking fan shape; none entering the head.

it is likely to be caught both deliberately and accidentally as bycatch. The inshore area and estuaries are also increasingly being impacted by various pollutants as a result of the expanding human population in the region. This species has a low capacity to tolerate impacts without irreversible change.)
