大小 / 重量 / 年齡
Maturity: Lm ? range ? - ? cm
Max length : 60.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 9808); 最大年齡: 25 年 (Ref. 52229)
背棘 (總數) : 6; 背的軟條 (總數) : 27 - 29; 臀棘: 2; 臀鰭軟條: 27 - 30. This species is distinguished by the following characters: body moderately deep and compressed, its depth 2.6 to 3 times in standard length (SL) (reported greatest depth of body in subadults at 2.3 in SL, Ref. 90102); dorsal profile of body uniformly convex; adults with a median, broad-based, tapering, horn-like projection extending directly anteriorly from snout at level of lower part of eye to more than 1/2 head length in front of mouth (first developing as a bump on forehead of young of about 10 cm SL; dorsal profile of snout from upper lip to base of horn very short, curved, and nearly vertical; mouth small; teeth small, spatulate, with denticulate edges, about 50 in each jaw; a continuous unnotched D VI,27-29; A II,27-30; pectoral-fin rays 15-17; pelvic fins I,3; caudal fin slightly rounded, without a filament from each corner; 2 bony plates on each side of caudal peduncle, developing moderate keels with age; colour of body olivaceous grey-brown to light grey, usually with vertical dark brown lines on body which break into small spots dorsally and ventrally; some individuals only with small dark spots; head with small dark brown spots or short irregular lines which become long and oblique on horn (dark markings on one pale phase may be faint or absent; in another phase the anterior third of the body may be distinctly paler than the rest); caudal fin whitish with a large diffuse dark blotch centrobasally in fin (Ref. 9808).
成魚藍灰色的到橄欖褐色的顏色, 通常灰白的前面地與在頰與咽喉上; 在身體側邊上的短的不規則的線; 在觸角上的對角線; 唇邊緣藍色.(參考文獻 3145) 亞成魚在頭部與身體上有深色的斑點。 (參考文獻 3145) 稚魚缺乏成魚的突出觸角。 (參考文獻 1602)
Inhabit mid-waters along steep outer lagoon and seaward reef drop-offs. Also found along rocky shores (Ref. 30573, 48637). Benthopelagic (Ref. 58302). Usually in small groups but form large schools in oceanic locations or on reefs subject to strong currents (Ref. 48637). Juveniles and subadults feed on benthic algae; adults feed on zooplankton. Pair spawning has been observed. Caught with nets (Ref. 30573). Minimum depth reported taken from Ref. 128797.
棲息於中層水域沿著陡峭的潟湖外部與臨海礁石海峭壁。 也發現沿著岩岸。 (參考文獻 30573) 稚魚與亞成魚吃底部藻類; 成魚吃浮游動物。 成對產卵已經被觀察。 用網捕獲了。 (參考文獻 30573) 最小深度範圍取自了參考文獻 30874.
