背面の脊椎 (合計): 6; 背鰭 (合計): 27-30; 肛門の骨 2; 臀鰭: 27 - 30. This species is characterized by the following: body depth vary from about 2.0 in SL (in subadults) to 2.4-2.6 (adults) in SL; with a tapering, bony, horn on forehead of adults projecting anteriorly at level of eye but not extending in front of mouth (horn first as a bump on forehead at a length of about 12 cm); dorsal profile from snout to horn straight, angle of about 45°; 2 peduncular plates with well-developed forward-curving knife-like spines; emarginate caudal fin when young, truncate with filamentous lobes in adult; males apparently with longer horn, larger peduncular keels and longer caudal filaments than females of the same size; body yellowish to olivaceous gray dorsally, paler ventrally, with blue peduncular plates and keel spines; lips whitish or blue; blue area is sometimes present around pectoral fin; dorsal and anal fins yellowish with narrow blue margins; caudal fin orangish basally, shading to gray, with a broad, pale greenish posterior border and caudal filaments are edged in blue; one transient color phase is a blotchy pale greenish zone below the spinous portion of dorsal fin that narrows and ends beneath the pectoral fin (Ref. 27362).
Adults inhabit channels, moats, lagoon and seaward reefs with strong surge (Ref. 48637). Benthopelagic (Ref. 58302). Typically occurring in small groups. Sometimes solitary (Ref. 90102). Juveniles in shallow protected bays and harbours (Ref. 48637). Mainly diurnal, feed on coarse leafy brown algae like Sargassum. Pair-spawning has been observed. Minimum depth reported taken from Ref. 128797.
