Distribution

NW of Port Hedland, Western Australia, to W of Cartier Reef, Timor Sea, and off Cape York to NE of Coolangatta, Queensland, also recorded from Arafura Sea north of Australia so distribution is probably continuous. Elsewhere the species occurs in the west Pacific: Philippines, South China Sea, Japan, Indonesia and northwestern and eastern and northeastern Australia.

Features

D II, 8-10; P 15-19; V 7; GR 7-8; BR 6; PC
Snout moderately long, more so in juveniles, sharply pointed in lateral view, tipped with a sharp, slender, diamond-shaped scute, anterolateral margin sharp, completely supported by bone. Mouth relatively broad, slightly restricted at corners, upper jaw teeth in broad uniform band, no teeth enlarged; lower jaw teeth uniformly small, in long, narrow band; chin barbel short. Underside of head uniformly covered with small, non-overlapping scales, except along narrow ventral margin of preopercle, anteriorly on lowe jaw and over gill and gular membranes; nasal fossa almost naked or with fine scales anteriorly and ventrally. Body scales large, with 3-7 divergent ridge-like rows of stout, triangular spinules, middle row strongest, with 4-6 spinules. First dorsal fin low, dorsal and pectoral fins without produced rays, outer pelvic-fin ray slightly elongate, almost reaching or scarcely extending beyond anal-fin origin. Anus slightly before anal-fin origin by 2-3 scale rows. Light organ short, externally visible as a short black fossa before anus; a narrow black midventral streak extends from before periproct to midway between pelvic-fin bases.

Size

Reaches a total length of 35 cm.
