Etymology: Scarus: Greek, skaros = a fish described by anciente writers as a parrot fish; 1601 (Ref. 45335); fuscocaudalis: Named in reference to the dark color of the large central portion of the caudal fin of the initial phase (Ref. 40928). More on authors: Randall & Myers.
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range 20 - 45 m (Ref. 90102). Tropical
Indo-West Pacific: Ryukyu Islands, Philippines, and Guam. Records from Indonesia and Papua New Guinea are questionable and confirmation is needed.

Morphology | Morphometrics
soft rays: 9;
Vertebrae: 25. Presence of 4 median predorsal scales; 3 rows of scales on cheek, the upper row with 6-7 scales, the middle row with 6 scales, and the lower row with 1 or 2 scales; 1 or 2 laterally projecting canines posteriorly on side of dental plates of adults; lips covering more than 3/4 of dental plates; dorsal fin moderately high, the longest dorsal spine 2.1-2.6 in head length; caudal fin truncate in young, double marginate in initial-phase fish, and somewhat lunate in terminal males. Initial phase fish brownish pink to rose pink, the throat and thorax green with green stripes extending posteriorly across abdomen; naked part of caudal fin blackish with orange lobes and a broad whitish posterior margin; body of terminal males pink and green, with blue and pink stripes ventrally; head blue with pink stripes ( a broad one on snout passing through lower eye to pectoral-fin base, and another from behind eye across upper part of operculum); naked part of caudal fin purple centrally, green posteriorly, the lobes blue with a pink submarginal band.
Found in coastal to outer reef crests and along drop-offs, usually in small groups (Ref. 48636); occurs at depths greater than 20 m (Ref. 40928).
