Description
A large silvery-grey to bronzy drummer, darker above, paler below, with a broad dark margin on the caudal fin, a rusty-coloured bar from the upper jaw across the gill cover, a pale bar under the eye and a small black spot at the lower edge of the caudal-fin base.
Body depth 36 to 51%, its width 13 to 21% of standard length; caudal peduncle slightly deep. Head length 24 to 30% of standard length, dorsal contour of snout before eye steep. Snout short, its length longer than eye diameter. Mouth terminal, number of lanceolate incisor-like teeth about 40 to 50 in adults (over 20 cm standard length). Gill rakers on first gill arch 5 or 6 on upper limb, 14 or 15 on lower limb (total 20 or 21). Dorsal fin with XI (rarely X) spines, the sixth or seventh spine longest, and 12 soft rays; base of spinous portion of dorsal fin longer than base of soft portion; soft portion of dorsal fin low, the margin straight, anterior soft rays as long as or a little shorter than longest dorsal-fin spine; anal fin with III spines, third spine longest, with 11 soft rays, anterior soft portion not elevated; longest anal-fin ray less than 2 times length of third anal-fin spine. Pectoral fins with 17 or 18 soft rays. Pelvic fins as long as pectoral fins. Caudal fin shallowly forked with bluntly pointed lobes. Pored scales in lateral line 49 to 53 (usually 50 or 51); longitudinal scale rows 52 to 58; scales above lateral line 10 to 12; scales below lateral line 17 to 19. Maximum total length 75/80 cm; commonly to 50 cm. Depth range : 0-30 m.
Colour
Body dark silvery grey or dusky grey dorsally, silver ventrally, with several olive brown or brown longitudinal lines on flank; head with 2 oblique olive brown or brown bands; one before or behind eye, and the other one below eye; dorsal and anal fins dark grey, the margin of soft portion with a darker band; pectoral fins silver near base, distal half slightly darker.
Etymology
Kyphosus: Greek, kyphos = bent, a hump.
sydneyanus : from Port Jackson, the type locality.
Distribution
Southwest Pacific: Australia (including Lord Howe Island), Norfolk Island, and New Zealand. Reported from New Caledonia.
Biology
Occurs in large schools in comparatively shallow water in the vicinity of rocky reefs. Feeds on weeds.
Inhabits coastal areas, primarily in shallow rocky reefs, often occurring in bays and harbours. May school with other kyphosid fishes in the northern part of its range. Juveniles often occur far out at sea beneath floating debris and seaweeds. Caught by gill nets, handlines, and spears.
