Color

• Initial Phase: body dark brown, edges of scales narrowly orangish, shading to dull orange-red on abdomen and thorax; Body with faint greenish yellow bars, these numbering 3-4 with anterior one predorsal, bars extending only to body mid-line; Posterior caudal peduncle and base of caudal fin greenish yellow, in small Initial Phase individuals caudal peduncle pale yellow to white, fading to orangish brown on death (also fading, a yellowish wash on upper half of head); Upper lip with narrow margin of salmon pink and submarginal band of dull blue-green; Lower lip and chin salmon pink with three transverse dull blue-green bands that join to median dull blue-green band ventrally; Fins orangish to reddish brown, dorsal and anal with faint median longitudinal dark band and narrow dark margin; Pectoral membranes pale; Pelvics with dark lateral margin; Dental plates white; Eye orange-yellow. Viewed underwater, Initial Phase individuals characteristically show irregular lighter bars against dark body coloration, the bars fading rapidly on death.
• Terminal Phase: scales of body green with vertically elongate rosy salmon bar, except abdomen and thorax green, and anterodorsally body and nape yellowish; Large whitish area on cheek bordered by blue-green; Lips faintly salmon, band of this color continuing from rictus to lower edge of eye and along upper edge of large pale area on cheek; Transverse turquoise band on upper lip and two on chin; Green band extending anteroventrally and two posterodorsally from eye; Dorsal fin salmon with blue margin, green at base, with median longitudinal green band; Anal fin blue-green basally, turquoise distally, the two regions separated by band of salmon; Caudal fin turquoise with salmon band in each lobe and short streaks of this color centrobasally; Pectoral fins largely turquoise with streak of salmon in upper part and whitish at base; Pelvic fins pale salmon with blue lateral margin; Dental plates greenish.

Etymology
Chlorurus: from Greek, chloros = green-yellow + from Greek, oura = tail. Referring to green-violet tail of type species, Chlorurus gibbus (Rüppell, 1829).
Bleekeri: in honor of Dutch medical doctor and ichthyologist Pieter Bleeker (1819-1878), who identified this species as Scarus quoyi in 1853.
Original description: Callyodon bleekeri de Beaufort, 1940 - Type localities: Padang, Sumatra; Ternate; Philippines; New Ireland, Ponape, Solomon Islands, Shortland Islands.

Distribution
Eastern Indian Ocean and western Pacific: Myanmar and Indonesia, east to Micronesia and Fiji, north to Philippines, south to northern Australia and New Caledonia.

Biology
Found in clear coastal and inner reefs; in lagoons and channel reefs. Feed mainly on algae. Females usually in small groups and maybe mixed with other species when feeding. Males solitary nearby. Oviparous, distinct pairing during breeding.
