narrow; horizontally based pectoral fins, placed low on the body;
snout sharply narrowed rostrally; 40-42 vertebrae; 7-29
gill-rakers; 11-12 anal-fin rays; caudal saddle and bar pattern
very faintly expressed; 7-8 branched caudal-fin rays; body finely
spotted; lateral line complete. Description:
head depressed; snout and tooth patches narrow; bodymore or
less fusiform; 17-18 abdominal vertebrae; 23-25 caudal vertebrae;
19 caudal-fin rays (arrangement: ii-7-8-ii) (Ref. 44050). Colouration:
bicolored, occasionally sharply so; dorsum tan or light brown,
venter pale and largely unpigmented, except for slight stippling
on the underside of the head and around anal and pelvic fin bases,
and scattered small spots; flank and dorsum well marked with generally
small spots, 1-1.5 times an eye diameter large or smaller,
with sometimes larger blotches posteriad; pectoral fin unspotted,
rays may be dusky in adults; pelvic fin generally opaque, unspotted;
adipose with pale distal margin, otherwise marked as dorsum; anal
fin matches body ground color, lightly spotted in adults, with
a pale distal margin in juveniles and adults; distal 2/3 of caudal
fin dusky in juveniles and young, bounded by a clear distal margin
and pale basal crescent; caudal fin in adults matches dorsum and
flank ground color, except for a clear distal margin, and is well
marked with fine spots in large adults (larger than 40cm
SL); caudal saddle and bar pattern weakly developed, even in young;
saddle slightly darker than ground color and extends to about
mid- depth; pale interspace slightly lighter than ground
