More Info

Distribution	Endemic to northern Australia from the Dampier Archipelago, Western Australia, to the southern Great Barrier Reef, Queensland. Inhabits flat sandy, seagrass or macroalgae areas at depths of about 5-85 m.
Features	Dorsal fin XII, 8; Anal fin 111, 10; Pectoral fin ii, 13-14; Lateral-line scales 27 + 2; Predorsal scales 5-7; Scales above lateral line 3-3 1/2. Body and head shallow, becoming moderately deep in large adults, body depth 26.6-37.1%SL. Eye large. Predorsal scales reaching forward to above midpoint between hind margin of eye and hind edge of preopercle. Cheek scales reaching forward to below anterior extent of orbit; moderately narrow naked margin along free edge of preopercle; subopercle with 5-9 uniserial scales reaching forward to below centre of eye. Lateral-line scales usually without accessory branches associated with sensory pore. Upper jaw with two pairs of prominent ventrally directed canines anteriorly, anteriormost about twice the size of second; upper jaw without posterior canines. Lower jaw with two pairs of prominent anterior canines, anteriormost much smaller than second; second pair strongly curved laterally. Caudal fin broadly wedge-shaped, upper and lower corners each produced into slight lobe. Pectoral fin rather pointed dorsoposteriorly, with lower ray produced, giving hind margin of fin lunate appearance.
Colour	Juveniles pale with narrow dusky midlateral stripe on sides extending from opercular margin onto caudal fin; small triangular dark mark extending from lateral stripe above pectoral-fin base toward lateral line. Initial and terminal phase individuals pale with hazy angled dark slash on side about midway between pectoral-fin base and dorsal profile of side; small dark spot at upper end of pectoral-fin base and short narrow dark mark near centre of hind margin of caudal-fin.
Fisheries	Wedgetail Tuskfish is regularly taken as bycatch in the prawn trawl fishery.
Etymology	The specific name is from the Latin sugillatum (= black and blue spot), in reference to the characteristic marking on the side of this species.
