Caudal peduncle is slender. Tip of upper
jaw reaches to hind margin of eye, but
not beyond. Jaws in adult males become
greatly hooked just before and during
breeding. A staggered line of teeth is
seen on the shaft of the vomer, but none
on the head of the vomer. Caudal fin is
fairly deeply forked. Scales are small.
Color of body is brown or green-blue
at back. Flanks are silvery and belly is
white back. Flanks above the lateral line
(rarely below it) have X-shaped black
spots. In freshwater, flanks are greenish
or brown, mottled with red or orange,
and with large dark spots with lighter
edges. This species grows to a maximum size of 150 cm and 39 kg (Jones,
2014).
