Color

• Juvenile at 9-12 mm, yellow green body.
• Juvenile at 12-24 mm, 3 broad lime green stripes broken by paler dots and irregular pale interspaces.
• Juvenile at 24-40 mm, body olive green with pale interspaces visible on head, posterior part of body, caudal peduncle and caudal fin pale blue, dorsal and anal fins with red and white flecks.
• Juvenile Greater than 40 mm, body olive green to pale-red brown (especially in larger individuals), pale interspaces on head give impression of dark longitudinal stripe passing through orbit, caudal fin and caudal peduncle pale blue to off white, dorsal and anal fins with prominent red and white flecks.
• Intermediate phase: body brownish yellow to light red, dorsum and caudal peduncle whitish yellow; 5 dark brown stripes on side of body following centres of scale rows; Fainter 6th ventral row; Body scales yellowish, edged with black; Head pale reddish, lighter on occiput, darker on snout, cheek and chin, dental plates white, iris orange-yellow; Dorsal, anal and pelvic fins reddish; Pectoral light hyaline reddish; Caudal light red.
• Terminal phase: body bright green, scales of body anterior to 5th dorsal ray with orange-red vermiculations; Dorsum of body and caudal peduncle abruptly lighter green; Occiput and upper snout green with dense mass of orange-red vermiculations; Cheek lighter green with fainter orange-red markings; tip of snout light green; Upper lip orange to pink; Two broad orange bands on chin, iris orange; dental plates blue-green; Dorsal and anal fins with green bases, blue-green distal margins and broad medial orange-red areas marked with blue-green spots and lines; Caudal fin green, basal area darker green, upper and lower lobes of caudal green with submarginal orange-red lines, central portion of fin with short orange-red lines; pectoral fins with light green upper rays, an orange-red central region, and blue-green ventral portion; Pelvic fins orange-red with blue-green anterior margin.

Etymology
Scarus: from Latin, scarus = scare, or sea fish (scare is the generic vernacular name for parrot-fishes). The Latin word is derived from Greek, skaros, same meaning as Latin word. The Greek knew this family throug Sparisoma cretense (Linnaeus, 1758), reported from their coasts, Aristote described the viscus. The genus has been described for the first time by Pehr Forsskål in 1775.
frenatus: from Latin, fraenatus = bridled. Referring to bands, one above and one below snout of males, joined near eye and extending to posterior edge of operculum.
Original description: Scarus frenatus Lacepède, 1802 - Type locality: Grand Océan équinoxial (Indo-West Pacific).

Distribution
Red Sea, Indo-West Pacific: East Africa, Socotra, Madagascar and Mascarenes east to Line Islands and Ducie (Pitcairn Group), north to southern Japan and Ogasawara Islands, south to Rottnest Island (Western Australia), New Caledonia, Lord Howe Island and Rapa.

Biology
Usually found on exposed outer reefs, sometimes in very shallow water. Juveniles occur among coral and rubble of lagoon reefs. Grazes on benthic algae. Generally solitary. Often in schools of mixed species when feeding. Parrotfishes change sex from male to female during their life cycle and vary in color depending on their sex and growth stage.
